At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Thorn Club Tour is a very versatile bike, and built like this it's a jolly tractor of a thing that's comfortable on the tarmac and off it. Add some luggage and it's the kind of bike that you could roll out of your garage, hop on and ride to pretty much anywhere in the world, whether the roads go there or not.

The Club Tour is now on its fifth incarnation, and it's a design classic that's stood the test of time: a Reynolds 725-tubed, externally routed steel touring frameset with as many braze-ons as you're likely to need. Thorn's sizing is worthy of note: The Club Tour Mk5 is available in five sizes from 50-61cm, with a long and a short option in each, making ten sizes in total. That allows you to fine-tune your fit both for your size and what kind of riding you're likely to be doing, offering a more upright and a longer, more stretched-out position.

The main change for the Mk5 is that Thorn has done a bit of work with the shaping of the stays so that the bike can now accept 650B wheels as well as 700C. The frame is compatible with either disc or rim brakes and there's a set of bosses on each chainstay to allow you to fit cantilever posts in either the 650B or 700C position, and a classic ISO disc mount externally located on the dropout that will take up to a 180mm disc.

The frame is mated with Thorn's new disc-only Mk3 fork which uses a Boost-standard 15x110mm thru-axle to beef up the front a bit. The frame is a standard 135mm quick release, so you'll need a very specific set of wheels built up in 650B or 700C depending on your preference. Our bike was specced with 650B wheels (Shimano Deore hubs and Ryde rims) and Schwalbe's excellent G-One Allround tyres in a 57mm width. That's a lot of tyre, but there's plenty of room in the Club Tour to fit them, even with full mudguards. Thorn reckons you can fit a 70mm tyre in there.

One of the selling points of the Club Tour is its versatility: the way it's designed means that you can start with the frame and end up with very different bikes, depending on what you use to put it together. Our test bike had a 3x10-speed derailleur transmission and STI levers on a drop bar (Shimano 105 levers and Deore mechs and chainset), but you could equally go for flat bars, or bar-end shifters, or even down tube shifters if you wanted.

Similarly, we tested a disc build but the frame also accepts cantis or V-brakes, and you can spec a rim-brake fork to match if you want.

The ride

Our test bike, with its big tyres and wide-range gears and comfy Brooks B17 saddle, is ideally set up for some serious touring, which isn't really a type of riding that's advisable right now, but I've taken the Club Tour out on local rides on a variety of surfaces, both loaded and unloaded, and I have to say I'm impressed by its ride quality and versatility.

Thorn Club Tour Mk5 - riding 6.jpg

You don't need more than about 40psi in the Schwalbe tyres to get a bike that feels reasonably efficient on the road, but there's enough air under your rims to make the bike really comfortable over broken surfaces, and on fire roads and trails the G-Ones have plenty of bite, especially in the dry.

Thorn Club Tour Mk5 - tyre tread.jpg

I started with some graded trails and ended up doing everything up to some of the more technical local bits on the Thorn, and although it wasn't the ideal bike for steep, rocky descents it can handle them well enough. The ideal riding for this build would be a mix of asphalt and gravel, but if you found yourself in more challenging terrain then you'd have plenty of capability in reserve without feeling that you're giving away too much on the blacktop.

Thorn Club Tour Mk5 - riding 5.jpg

The long wheelbase and generous trail on this bike mean that the steering can sometimes feel a bit vague at low speed, especially if you're running the tyres a bit soft for off-road use. But at cruising speeds the bike behaves very predictably, and if you load the fork with panniers then the slower steering will likely be welcome.

Thorn Club Tour Mk5 - riding 3.jpg

Given that the Club Tour is a bike that's almost always going to be running a rear rack it seems odd that the Thorn doesn't have two mounting points on the rear dropout for mudguard and rack. It's not a huge issue, but neither is it a tricky thing to do: there's plenty of space there.

If you were really worried about overloading the mounting bolt you could always migrate the mudguard to the upper disc mounting bolt on the one side, so that at least one of the mounts isn't doubled up.

Other than that, you're not short of places to put stuff. There are low rider bosses on the fork, two standard bottle mounts in the main triangle and a third on the bottom of the down tube.

Thorn Club Tour Mk5 - bottle cages.jpg

You don't quite get the wealth of mounting points you might on a bikepacking bike, but here the expectation is that you'll be fitting racks and using traditional luggage, and the bike is very well set up for that.

Choose your own spec

In terms of the build it's not really worth picking holes in anything particular: this is the build we asked for, after all, and like I've already mentioned you can build it up pretty much any way you fancy. I'd be happy to roll this bike out of its big box, pump the tyres up (not too hard), bolt on some carrying capacity and head off on any length of trip you care to imagine.

Thorn Club Tour Mk5 - riding 2.jpg

The triple chainset (48/36/26) and wide ratio cassette (11-36T) give you a huge range of gears, though it's worth noting you could go bigger at the back (say an 11-42T) if you were going to be attempting steep or unmade climbs with a full load; you're much more likely to run out of ratios going up than down.

Thorn Club Tour Mk5 - drivetrain.jpg

Although the TRP Spyre mechanical disc brakes lack the bite of hydraulics they're still very efficient, and also extremely easy to set up and fiddle with. I'm a big fan of hydraulic disc brakes but I'd forgo the performance benefit for the bodge-ability of cable discs if I was going anywhere remote.

Thorn Club Tour Mk5 - disc brake detail.jpg

Similarly with the cable routing: everything's in plain view, which makes for a slightly shorter maintenance cycle than internal cables but also means that getting things fixed out in the field is a whole lot more straightforward.

Value and conclusion

This build comes in at a grand total of £1,870.86. That's a fair whack for a touring bike, and similar to the Genesis Tour de Fer 30, which has a slightly lower spec overall but does come with racks and dynamo lighting. A Surly Disc Trucker comes in a bit under this price in a 3x10 build with bar-end shifters. The Trek 520 is good value at £1,300, albeit with a lower spec, and the Dawes Ultra Galaxy is £100 less than that, with a similar build. Those two bikes don't have the kind of clearances the Thorn gets, though the more bikepacking-orientated Trek 920 (£1,700) does. Salsa's Marrakesh is another option, with a Shimano Sora build coming in a bit more expensive than the Thorn.

Anyway, it's not cheap, but if you're looking for something you can build to your exact specifications and depend on to do the job, it should be one for the list. That job could be anything from the commute, and lugging the shopping once a week, to tackling the Carretera Austral or the Karakoram Highway. So long as you're not in a big hurry, I'd back the Club Tour to get you there.

There isn't really a 'range' of Thorn touring bikes, they're more specific frames for specific purposes. This is Thorn's "take on a traditional touring bike".

Frame and fork

Overall rating for frame and fork

Tell us about the build quality and finish of the frame and fork?

Neatly welded, nicely finished. Red is bold, also available in gunmetal, British Racing Green and blue.

Tell us about the materials used in the frame and fork?

Full Reynolds 725 tubeset.

Tell us about the geometry of the frame and fork?

Our 61S bike has an effective top tube of 575mm and a 214mm head tube, but there's also a 61L that's 40mm longer and a bit lower. All the sizes are available in two lengths so you should be able to get a good fit.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

It fitted me very well.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

Very comfortable, easy to get on with.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

Absolute stiffness isn't the main aim of a tourer but it's plenty stiff enough to cope with loads and the weighting they put upon the frame.

How did the bike transfer power? Did it feel efficient?

Yes, especially when seated.

Was there any toe-clip overlap with the front wheel? If so was it a problem?

A bit of overlap due to the mudguard but nothing to worry about.

How would you describe the steering? Was it lively neutral or unresponsive? Relaxed.

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

It's a pretty relaxed ride, great for cruising with minimal input.

Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?

The 57mm tyres soak up a lot of surface chatter. I'd probably go a bit thicker on the bar tape. Brooks saddle was comfy out of the box.

Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?

I wouldn't really change anything.

Which components had the most effect (good or bad) on the bike's efficiency? would you recommend any changes?

You could make the bike more efficient on the road with a slightly narrower and less aggressive tyre, say a 40mm Schwalbe G-One Speed. That's at the expense of its off-road capability though.

Anything else you want to say about the componentry? Comment on any other components (good or bad)

You can spec the bike how you want, so picking on things here wouldn't be that helpful, but I didn't have any complaints really. Maybe a thicker bar tape, but that's it.

Your summary

Did you enjoy riding the bike? Yes

Would you consider buying the bike? Yes

Would you recommend the bike to a friend? Yes

How does the price compare to that of similar bikes in the market, including ones recently tested on

It's nearer the top end than the bottom given the spec, but you wouldn't say it was bad value. Bikes like the Salsa Marrakesh and Genesis Tour de Fer are broadly comparable to this build, but with the Thorn you get the benefit of being able to custom-spec bits and bobs which isn't an option on mass-produced bikes.

Rate the bike overall for value:

Use this box to explain your overall score

It's a really good and versatile touring bike, and built like this is a lot more capable than just sticking to the tarmac. It's not cheap but it does represent decent value.
