The Mt.-Tura forks are made using world famous, top quality Reynolds blades, with stainless steel fittings and a military grade, malleable steel "twin plate" fork crown. There are fittings for a lo-loader carrier, direct fitting mudguards, a bottle dynamo and crown-mounted dynamo headlight.
The 28.6 mm dia Mt.-Tura steerer tubes are a whooping 400 mm long!
The forks have an Axle to crown length (L1) of 430 mm.

(This compensates perfectly for either 80 mm or 100 mm travel forks, either of which actually rides at around 430 mm in neutral conditions).

The increased offset (52 mm) of the Mt.-Tura forks improve the steering characteristics of most mountain bikes apart from extreme off road use!

We do not (and will not) fit disc brakes to resilient steel forks. The leverage of the caliper on the rotor can pry the wheel from its dropout. A through axle dropout (and hub) would prevent this but, to fit one, we would have to use very large diameter blades; these would then be horribly uncomfortable to ride, there is enough rubbish on the market without us adding to it! A right hand dynamo is required as the boss is on the right hand blade facing forwards. You will need a Thorn Stainless Steel Sliding Dynamo Boss for Thorn Forks with Boss Type 3 / L-Shape X-Long (part number 19581) to mount the dynamo.

Rack Braze Ons Require An M6 Bolt
21 Feb 2016
2 / 5
ConsPoor product information
ProsLong steerer could be useful
The forks seem fine but I can't fit my Tubus front racks because they use M5 bolts whereas the fork takes M6, which won't fit through the slots in the rack. I will have to take a file to the racks which will no doubt void the warranty and increase the risk of corrosion.

Pity Thorn/SJS Cycles don't give the rack mount thread size in the product description as Tubus do as this is important information.
Quality Hardware, Poor Documentation

ConsPoor Documentation
ProsQuality Hardware
The forks are top quality (as they should be for the price).
But the documentation that goes with the forks is poor (unlike the other "rubbish on the market"). When I convert forks, I expect there to be compatibilty problems, but it would nice know these before I started work.

Here are some questions one should ask before buying this product:

What is the maximum tyre width that these forks can take? (I have to let air out of my tyre to remove the wheel!)
What thread size is used to mount to accessories? (All my existing bolts had to be replaced)
Is the product "non standard" in any way? (The mudguard mounting hole does not exist at the rear of the fork crown preventing the fitting of a steering damper).

If more time was spent thinking about what the customer needs from the product and less time attacking the competition, this would have been a 5 star review.
Great Forks

I recommend this product
ProsHigh quality, strength
Bought these to replace the suspension forks on my Thorn Catalyst. Easy to fit and plenty of bosses available for mudguards front luggage etc.
These forks are high quality, light but strong and the black colour looks good with the red frame.

Tyre Clearance
25 Apr 2014
Hi there, i have a question about tyre clearance. Big Ben Schwalbe balloon tyres 2.35 will fit the fork?
I actually use cantilever brakes that, i imagine, will not work with this fork ?
I'm building a touring bike from a steel MTB Trek from the 90's (suspension corrected): my actual rigid fork is 413 mmm L1 with a 45 mm rake. Will this Thorn fork increase the stability ?
Many thanks in advance and have a nice day!
