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 390mm long!
The forks have an Axle to crown length (L1) of 420 mm.
Fork offset is 48mm

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

The dynamo light boss is on the right hand blade facing forwards. You will need a Thorn Stainless Steel Sliding Dynamo Boss for Thorn Forks to mount the dynamo.

- Steerer: 1 1/8"

Overall Product Rating 4 / 5
Excellent quality forks

I recommend this product
Had a medium priced MTB with rubbish suspension forks, decided to upgrade with good quality steel forks, very pleased with the ride. Comparable to my British Eagle 531st toureristique, with more braze on's to aid rack and mudguard fitting.
They weigh less then half the previous junk, so well pleased with the predictable handling.

You will need to fit new brake cable to your now facing backward v brakes! No issues running like this at all.
Nice forks

ConsM6 braze-ons as other have mentioned.
ProsThe right geometry.
Used these to replace the 100mm fork on my Altitude. I knew it would drop the head tube somewhat but figured the steep angles would be more appropriate for its use as an around-town cruiser anyway.

Forks came, they fitted up right away. Zero issues. I was the one who asked the question about HS33 and I ran into just one small problem with them ... the brake bracing arch that is normally used outboard of the brakes wouldn't fit ... it would hit my downtube. But I don't really notice a difference.

I don't notice the steeple angles, BTW. Bike's still great to ride.

I'm using the fork with Schwalbe Big Apples w/o issue.

Oh, wish there was a hole all the way through the crown for mounting lights, front racks, etc. As it is, there is a threaded hole in the back of the crown for mudguards but it only goes halfway through.
Rack Braze Ons Require An M6 Bolt

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
By Robert Winstanley

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.
Questions & Answers (10)
can i use this fork on a small surly troll which is about 5 year old
22 Jan 2021
Sadly without having the full-frame specifications it's very hard to say. We would recommend getting this information first, then you can review new forks compared to the OEM ones to see if they are compatible.

Which handing of bottle dynamo fits the fork, left or right?
28 Aug 2020
Right-handed for the bottle dynamo- for this you will need the Thorn Stainless Steel Sliding Dynamo Boss (SJSC PART CODE: 7051).
Can I use a SA XL-FDD hub with this fork?
01 Mar 2020
Yes, this should be fine.

Thanks - 03/03/20
Is this same fork available with the canti studs on the front?
07 Jun 2019
The fork is spot-on for all its dimensions, but I wanted to run cantis and so need the studs on the front, not the back.
Is this something you do?
Hi there,

unfortunately, we do not stock this option,

Is the recommended dynamo boss out of stock?
05 Aug 2018
The "Thorn Stainless Steel Sliding Dynamo Boss for Thorn Forks with Boss Type 3 / L-Shape X-Long (part number 19581)" does not appear to be available on your website. Am I missing something?
Hi there,

The type 3 is no longer produced, the type 2 - SJS Cycles part number : 7051, should work fine.

Do these forks have a threaded or threadless steerer?
20 Jun 2018

These forks are 1 1/8" ahead compatible so the steerer is threadless. I hope this helps.

Kind Regards
Magura HS33 brakes and tire clearance
24 May 2018
Hi there,

Are these forks compatible with Magura HS33 hydraulic rim brakes. I can see the "backwards" brake mounting leading to some unforeseen incompatibility.

Second, what's the largest 26" tire that will clear?

We have no experience with fitting those brakes, but we cannot foresee fitting issues. The tyre max is 2.0" with guards, 2.125" without.

Mt Tura Vs Nomad Fork?
10 Mar 2017
What is the differnce between Mt Tura and Nomad Forks?

Do they BOTH have a 400mm steerer. I have 3 x Thorn Forks all with 400mm steerers . . .just checking.

The Mt Tura forks use a larger offset (or rake) that the Nomad forks. The Nomad forks have a 390mm steerer rather than the full 400mm.

Tubus Tara Lowrider Rack On This Fork ?
19 Feb 2017

After reading the rewiew about M5 and M6 bolts, I would like to know if I can mount a Tubus Tara Lowrider Rack for 26 on this fork.


Technically yes, but not easily and without some form of modification. These racks are designed to use M5 bolts where as the Mt Tura fork takes M6 bolts. We still recommend the Thorn low rider for use with the Mt Tura fork as this has been specifically designed around M6 bolts.
