Thorn Nomad Mk2

The Thorn Nomad MK2 is my bike of choice for bicycle touring. I purchased the bike several years ago it was based, in part, on reviews from people on cycle touring blogs. Its now my turn to add my review of the bike which is on its third tour and completed around 20000km.

First Tour on the Thorn Nomad MkII

I purchased the bike online and picked the bike up at their shop in England. The first tour commenced at the front door of the shop and lasted for about 1500km around England, France, Luxembourg, Belgium and Holland.
First Tour in Europe

Second Tour on the Thorn Nomad MkII

The second tour was around the greater Blue Mountains of Sydney, Australia. About 1500km of back roads, part of which was on the National Bicentennial Trail which consisted of rough tracks and dirt roads. On this second tour I learned that I needed to lighten up my gear.

I also used the bike for commuting in my home town of Darwin, Australia. The bike is heavy with a very rigid frame and not the best commuting bike. Load the Thorn Nomad Mk2 up with some weight in the panniers and the bike rides very well. I guess that’s its purpose in life and why I bought it.

Third Tour

The third tour on my Thorn Nomad Mk2 started in Tasmania, Australia before flying to Alaska and cycling to the Mexican border, including cycling to Prudhoe Bay in Alaska and standing on the frozen sea and cycling to Inuvik in the Canadian Arctic. I also canoed 715km of the Yukon river with the Thorn Nomad Mk2 strapped to the canoe with me. I hiked 698km of hiking trails and carried all my hiking gear with me, most of which is the same gear as my bike touring gear anyway. Eventually I will cycle from Alaska to Argentina.

There is little to dislike about the bike. The fit and finish is good. Its reliable and works as promised. I am using the Thorn Comfort handlebars but think I will swap them out, they just don’t work for me. I’m not sure what I’ll replace them with, I’d like to try several different styles of handlebars such as the ‘Jones Bar’ or ‘Butterfly Bar’. Time and money will tell what happens in the future.


I have been running Schwalbe Dureme 26 inch x 2 inch folding tyres. They have had a hard life with about 4000km or dirt road use and about 16000km or road use. As the tyres started to wear I had consistent problems with flat tyres. The front tyre is still in use at around 20000km. The first rear tyre exploded in Alaska after about 8000km. I think it was my fault, I may have (did) put too much air in the tyre and it blew out the side wall. The second rear tyre has about 12000km of travel. Both tyres should have about 2000-5000km more wear but they are both a bit tired with lots of minor cuts on the tread and side wall. I plan to replace them with SCHWALBE Marathon Mondial very soon.

Rims and Brakes

The Rims are Rigida Andra 26 inch rims with Ceramic Tungsten Carbide coating and Swisstop blue brakepads. The rims have no sign of wear. I have not had to adjust the tension of the spokes, they still spin true and none of the spokes have broken. The brake pads at the rear were replaced at about 13000km but the front brakes pads were fine and have not been replaced, they have done 20000km! I replaced the brake cables at about 13000km.

Rohloff Hub

The Rohloff hub is a high end specialist internal gear hub known for its reliability and long term problem free use. The Rohloff developed an oil leak which was first noticed after a airplane flight. There was oil covering the interior of the bike box. I didn’t think too much of it until there was a pool of oil on the bottom of the canoe when I set off canoeing the Yukon River with my bike strapped to the canoe.

I took a photo of the oil leak and sent it to Thorn to assess. They advised it wasn’t a problem so I put up with the leak. Each time I change the oil as per the manufacturers recommendations I notice that there is no oil left in the hub. The new oil injected into the hub leaks out over time. Most of it leaks onto the chain but also leaks onto the rims and sometimes onto the ground, the leak increases if the bike is laid on its side rather than on the kickstand. I’m assured this is not a problem but I’m not so sure!

The gear change cables have done 20000km I will replace them soon, rather than wait for them to break. The gear change selector on the handgrips will also be replaced due to wear, it could last longer but it makes sense to overhaul the whole gear system at 20000km. Overall, despite the oil leak the hub, the hub has performed well, no problems with gear changes and no excessive noise. Changing the oil every 5000km is easy (even if there’s no oil left in my hub when I change it!).

Oil leak on the Rohloff Hub. Seems excessive to me but the staff at Thorn think its nothing to worry about! Took only a couple of  hours for this amount of oil to leak out!

Chain and Chainrings

The chain and both chainrings were replaced after 13000km. They could have lasted longer but several teeth on the front chainring had broken off. I started with a 40 tooth front chain ring but replaced it with a 38 teeth chain ring which assisted with the steepest of steep climbs. Rarely do I need the lowest gear unless the climbs are above 10% with the new gearing.

I replaced all the running gear at the same time, the front and rear chain rings and chain. The current chain and chain rings have now done 7000km with little sign of wear. I will reverse the chain rings soon to increase their life and the chain has stretched so needs a chainlink to be removed as I am unable to adjust the chain any further. The chain is adjusted via an eccentric bracket which is adjusted with the tool provided by Thorn.

I had an issue in Canada when the eccentric bracket seized and I was unable to adjust the chain. To try and loosen the bracket I used WD40. I also hit the cranks to try and loosen the bracket but unknowingly at the time I broke the bolt holding the crank. Eventually I loosened the bracket but soon after, while peddling uphill the crank fell off. A passing motorist luckily had a spare bolt that fitted and I made it to a bike shop to effect proper repairs and re-grease the eccentric bracket.

I will pay more attention to this type of maintenance in the future. While having a seized bracket I managed to bend the Eccentric Bracket adjustment tool, it will need to be replaced. Poor preventative maintenance from myself is to blame, I think. Oh, and maybe I shouldn’t have ridden on all those beaches while in Tasmania!

Rear View Mirror

I fail to understand how cyclists can tour without a rear view mirror. I like to have an idea what is going on all around me. If I am cycling on a narrow road with no shoulder and a truck is coming towards me and a sight a truck behind me in my mirror then I’ll just pull off the road. In 20000km I’ve only had to do it 3-4 times. I’d rather get off the road and ride another day, rather than stay in my lane and risk being hit and injured or worse. Just my opinion, not everybody agrees with me on this point. After 20000km the CatEye Bicycle Mirror is quite scratched and I’ll replace it with the same model, unless I replace the handlebars and it doesn’t fit!

GPS and Navigation

I used a combination of paper maps, Garmin Edge 810 GPS, Google Maps and the Pocket Earth PRO Offline Maps App on Iphone for my navigation.


Garmin Edge is not only my GPS but also my trip computer to determine my speed, grade of climb, daily distances and a plethera of other stats. The info about the days ride is extensive and fun to look at either while riding or at the end of the day. It is loaded with Garmin Maps that allow me to make route etc. The routing function is customisable and very frustrating. All up I am wanting to get rid of the GPS and use only my smartphone for all navigation and Bike trip computer stats.

Mapping Apps

Pocket Earth PRO Offline Map is an app that allowed me to download maps for offline use. The topo maps give a good indication of the sort of terrain that you will be cycling through and offline Wiki info on towns and attractions. It is able to create routes and give turn by turn directions. I am also able to search out campsites and places like McDonalds and other places in town for free WiFi (not the food). Employees tend not to be paid enough money to care if a cyclist comes in, sits down and uses the free WiFi! I liked it. It has routeable maps which can be used while offline and appears very accurate. I’m still learning the power of this app and the more I use it the more impressed I am.

I use a Pletscher Esge  rear mount bike stand. A lot of cycle tourers are against kickstands. I’m not sure why. Maybe they should re-assess their reasons. I have toured without a kickstand and it annoyed the crap out of me having to find something to lean the bike against or lying it on the ground often in mud. For my second tour I used a clickstand, a small lightweight pole made with the same material as most tent poles. I found it also annoying and it broke part way though the tour. Not that I overly cared as I was not happy with it by this stage.

I found the Pletscher Esge kickstand to work well on all but the softest sand and mud and even then I still managed to make it work for me. Thorn states that they void the frame warranty if a kickstand is used. I say that if their bike is a strong as they state, and they are very boastful of its strength then I surmised that its not a problem, and so far its fine. I don’t load my bike with 100kg of gear which might bend the frame in the wrong circumstances so I don’t think its a problem. Very happy with the stand.

Electrical charging

The most common question I have received is in regards to the front dynohub and how I charge my electrical gear. I use a Son Schmidt Dynohub which powers my front headlight and was also conected to the Sinewave Revolution USB charger and the PowerGen 12000Mha Battery. With this combination and when cycling at speeds of about 15km/h it charges my phone at the same speed as mains power.

When traveling slower it still charges ok but not as quick. When I’m not charging my phone directly I charge a PowerGen 12000Mha battery, I use this to charge up my GPS every night as well as all my other USB devices such as my Kindle, headlamp, steripen, etc.

I charge my computer off mains power as I travel. Places such as fast food restaurants, coffee shops, RVers who let me charge on their power etc. I started this tour with the Pedalpower plus system. It was poor quality and continually failed me, I was not overly impressed. So far, after about 9000km the Sinewave Revolution has exceeded my expectations. I am very happy. The PowerGen battery is just a cheap battery I bought on EBay. It works fine and holds more than enough charge for extended cycle touring when used in combination with the Sinewave Revolution.

Cycling at speed charges all the USB devices, but it also works at slower speeds as long as its above 5km/h



I had a Brooks seat which failed in Alaska when the adjustment at the front of the seat broke, I was unable to affect a repair without waiting for spares to arrive. I wasn’t prepared to wait an unspecified amount of time so I replaced the seat with another found in a bike store. The new seat, called a Phorm seat, seems to work OK for me so I’ll keep hold of it until it wears out. Its traveled about 12000km so far and I’m happy enough with it.

Panniers and Frame Bag

Custom Made Frame Bag

When I decided to get rid of front panniers I toyed with the idea of getting a frame bag. A girl I hosted through warmshowers, Marie, was a genius at sewing and made one for me from offcuts of shade sail material. I was able to store all my spares, tools, pump, rope, gloves, hat, raingear etc.

The framebag worked well on my Thorn Nomad Mk2 but was not completely waterproof in heavy rain. I seam sealed the stitching but this didn’t solve the problem, I suspect it is the zippers which are not waterproof. It could be solved  by fitting waterproof zippers or replacing with a length of velcro as a flap. Wrapping things in Zip lock bags also works. I love the small bag between the frame and rear wheel. It stores my Rohloff Oils, spares and tools that I very rarely use. I will look into waterproof zips or velcro in the future, until then I’ll use waterproof bags.

Rear Panniers

My choice was to use the rear Ortlieb Back-Roller Classic Panniers. I managed to break the bottom mounting bracket that is shaped like a smiley face. Instead of replacing it I used a combination of superglue and reversing the mount as a temporary fix. This has lasted over 12000km and I’ll replace it soon. Both top mounting plastic mounts are bent and no longer straight. It is both waterproof and dust proof. The Ortleib Ultimate handlebar bag worked well and is also waterproof and surprisingly dustproof. I also used the map case from Ortleib which worked well. All work very well, highly recommended.

Rear Rack bag

On the rear rack I use an Ortlieb Rack-Pack 49L, bright yellow. It stores my hiking backpack, tent poles and jacket. When covering long distances between re-supplies it is loaded with extra food etc. Several of the buckles broke but are still usable, I will replace them and take a spare or two with me. Initially I wasn’t impressed with the rackbag but its grown on me and cant find a better way to store extra gear and keep it both accessible and waterproof.

I also use 2 Revelate Design feed bags on the handlebars which I use as waterbottle holders. While in Alaska and Canada I used one of them as a Bear Spray holder, great for quick access if needed, which I didn’t! Some of the stitching has broken and needs to be repaired.

Suspension  vs Normal Forks

I have toured with the supplied fixed fork that comes standard on the Thorn Nomad Mk2 and with Rockshox coil suspension. My choice of coil suspension over air suspension was made because I thought if there was an air leak then I may have a huge problem and may not be able to ride.

I was not completely happy with front suspension, let me explain. By having front suspension forks I thought I would have a more comfortable ride and be able to move over rough ground faster. Well, it sounds good in theory but in practice I found it wasn’t the case. While loaded I was not able to travel fast over rough roads, when I did I risked pinch flats on the rear tyre. After several pinch flats I learned that I could go no faster over rough roads with suspension forks.

On stoney roads or mildly rough roads the suspension was of benefit but those same roads could be ridden comfortably with solid forks at the same speed. When the bike is loaded it works well with the solid forks, they seem to flex just the right amount. In fact the more weight on the Thorn Nomad Mk2 the better it rides.

The next things was technical mountain biking. Riding the bike unloaded over technical trails was not as great as I expected. It is not a mountain bike. Yes, I knew that already. Its a heavy, rigid touring bike.


In conclusion the extra weight and money of front suspension was not worth it. I never bought the bike as a mountain bike. Loaded or unloaded the bike did not perform much better with front suspension. I tried mounting water bottles on the front forks, the bottle holder kept breaking. One time they broke and sent the water bottle into the front spokes while at speed. I was lucky my front spokes didn’t break. I will not be mounting water bottles on the front fork again. Maybe there is a better, stronger way of doing it. I’m open to suggestions from anybody.

So the end result is I will install my original solid forks in the future. I’ll save about 1kg in weight and have better reliability issues.

The bike performed well. It exceeded my expectation. There were many envious cyclist who wished they had the same bike as me. Highly recommended.

If anybody has any questions regarding my Thorn Nomad Mk2. Feel free to ask and I will answer them.

    Hey Brad Awesome piece. I’m thinking about buying a NOMAD too.Its reassuring to read a positive review. I have a big question- what do you load it to in kilograms? The instructions say up to 60kgs, later ‘at its best at 35kgs’. do you carry scales with you. Steve at Thorne said too many bumps and you could shear off the bosses at the max weight. Bruce Gordon says that i should run away from anyone offering me a bike that they say will carry 100lbs +. cheers, Andrew

    • BikeHikeSafari

      I carry an average of 20-25kg but on some long unsupported sections of touring I’ve carried up to 50-60kg of load, 15 litre of water and a week or more in food. The bike handles the weight fine, in my experience the more weight on the bike the better it rides. 35kg should be no problems, I highly recommend the bike of you want a solid bike for touring, if carrying less load than 20kg there are many cheaper options than a thorn. Hope that helps.

    I have a Thorn Nomad Mk 2, and have never experienced the oil leak problems you have on my Rohloff. I would get in touch with Thorn again, and insist that it’s DEFINITELY a problem.

  3. Peter Pro

    Hi, as Thorn AND Rohloff state, You can easily ride on with no visible (drainable) oil in the hub, as there is still enough oil inside on the moving materials to lubricate them between the intervals of the next oil change (and refill).

    Regarding the front suspension I use a Magura TS6 (successor of the Magura Menja) and I am very happy with it. I dont mind weight, as everything on this bike is heavy and solid. The ride with the Magura TS6 is much smoother on any kind of surface, of course most recognizable on rough surface. The ride with the rigid Thorn fork is not especially comfortable when cycling unloaded (at the fron wheel). BUT it is VERY comfortable the more loaded the bikes, especially the front wheel with the low loader, gets!! And that´s what the bikes is built for: heavy loaded touring. So by all means I am very happy with the bike and its performance! Thanks for providing Your detailed experiences, regards, Peter

    • BikeHikeSafari

      Thanks Peter. My suspension girls are 1/4 the price of your forks, so far they’ve done 20000km and working well. I’d love better forks such as yours but can’t quite justify paying for them. Glad you like them.

    Nice review
    I ride a Thorn Raven
    A light weight Nomad
    Last summer in rode 2,500 Km through Tajikistan and Kyrgyzstan fully loaded across the Pamir Highway. 4,000m high roads.
    Much of it unpaved.
    Anyway, the Raven and Rohloff did their jobs perfectly.
    I wrote to Thorn and asked them what kind of terrain did they build the Nomad for?
    It must be like a tank?
    Not taking anything away from Nomads but please consider the Raven as well.
    It did the job for me.

    loved reading youre review and blog. I have question perhaps open to all. I’m torn between a Thorn Nomad, a Surly Disk Trucker as well as a custom built Soma Wolverine based bike… any comments on that?

    • BikeHikeSafari

      I’m not familiar with the other bikes. The nomad is a real heavy duty touring bike. About as solid as you can get. It’s now done over 25000km. So far so good

    • Paul

      Hi srahul, if you decide on the Thorn Nomad II, and you’d like to avoid the expense, I have mine for sale – a great condition, top spec, tonka Yellow Thorn Nomad Mk II – bought 3 years ago, but not used as much as I’d hoped so reluctantly selling. If you look at the Thorn Cycles website and study the Nomad Mk II brochure, the one I’m selling is absolute top of the range pictured as the ideal build, a no expense spared Rohloff equipped model – original outlay £2,400. Designed to go around the world, and keep going around! If you’d like pictures, you can let me know via:

      • ANDY

        how could you sell a thorn after only 3 years??? I’d certainly buy a thorn. i looked into surly’s, they carry max 25kgs of pannier, and 150kgs of rider. still, im looking at getting a surly trailer for shifting house and stuff.

  6. ANDY

    Dear bikehikesafari,
    have you had any trouble with your rohloff hub slipping? like pushing down hard on the pedals, and a crunch and grind as the hub clumsily shifts down?

    • BikeHikeSafari

      No. I always change gears mid stroke. Meaning when my legs are imparting the least amount of pressure. When they are at the very bottom or top or the stroke. Does that make sense. When I first changed to riding with a rohloff it would clunk into gear if I changed gear when I had max pressure on the pedals.

      • ANDY

        what i’ve had is my finger nowhere near the shifter (i’m not changing), but i just change the pedalling pressure (increasing it), and the hub slips, grinds, crunches down to a lower gear.

      • BikeHikeSafari

        Never happened. Maybe contact Rohloff

  7. Christopher Culver

    I suspect your Rohloff oil leak is due to not putting a new daub of Loctite (one of the oil-proof numbers) on the drain screw each time you replace the oil. The drain screw does not create an airtight seal without Loctite, and the air pressure inside the hub gets high enough to push the oil out.

    I’m surprised to hear that you use a 49L Ortlieb rack pack. I thought that size was only for motorcycles. Does it easily clip to the back panniers?

    • BikeHikeSafari

      The oil leak is not from the grub screw but from the seals on either side of the axle. So I suspect loctite would make no difference. The 49L works well, specially on long food/water carries. Generally it only carries my hiking backpack and empty water bottles etc. it clips in easily but I also use bungy cords to stop it moving.

  8. Wai Sing Lee

    Hi, sorry for being so late to the conversation. Here’s two cents from a guy that’s been using a Rohloff since 2009. The first pic or gush of oil looks a bit frightening but I too don’t think it’s something to worry about. I’ve had gushes of oil coming out of my hub at the oddest times where there would be a leak days, weeks or months after a filling up. Not as huge a quantity as in the pic, though, and not from the grub screw hole. Effectively, your rear wheel’s rims and spokes will be covered with a thin layer of oil all the time.

    And, when I start my annual oil change, I almost never get any old oil out. I’m pretty sure it’s not dry inside the hub but the gears are certainly not sloshing in oil the whole year.

    So, hope that allays any fears. Rohloff themselves are very responsive to issues. Ride safe!

    • BikeHikeSafari

      Several years later the oils still leaks and the hub still works fine.
