Carbon Fork 1 1/8 steerer that will take 28mm tyres

[JennyFarthing]

Hi after much messing about trying to get a 28mm tire on my Lynskey Cooper, I've decided that I'll have to swop out the fork. But I can't find a Carbon Fork with an alu 1 1/8 steerer that will take 28mm tyres? I found these but they are designed for 57mm drop brakes not sure my Shimano 6700 Ultegra caliper will work on them? Anybody had similar please?

How much are you willing to spend?

I think your most realistic option is to buy some forks for canti or disc brakes and do a "full swap" - forks, brakes and potentially front wheel depending on if the forks you buy are QR or thru-axle. You can get a cable-pull disc brake so no need to change the shifter (although, depending on the exact shifter you have, you may have to employ some kind of cable pull adjuster to ensure that it all works).

Ritchey make a number of such forks:

Those are for canti brakes with a QR wheel.
The main issue with tyre clearance is less about the forks and more about the brakes. Wider tyres simply won't fit through regular dual pivot brakes, that's the narrow point, not the fork (although, yes, the fork is also narrow to mount the brake on, it's a bit chicken/egg). This is one of the major plus points of disc brakes that very few people bleating on about not needing that much braking power realised - braking was actually secondary to the massive extra tyre clearance opportunities that disc brakes opened up.

You're unlikely to find too many carbon forks with aluminium steerers by the way. There were a few cases of alu / carbon interfaces debonding, it's always much stronger to build a fork from one material and use a carbon steerer.

Thanks for the response I only seem to have this option but I don't want to use a different calliper really:

I've a new unused steel fork in my shed. Came from my on one pompino as a spare when I specced an upgraded carbon fork .
It has bags of clearance. 1,1/8" ahead, 700c wheels. Will take 35mm tyres with mudguards.
Like the one shown in this thread, but not mine.

a pompino fork won't accept any caliper though i don't think (although they were made for a few years over a few different designs.)

FWIW Ambrosio may well do the kind of fork that you are looking for. ISTR that they at least used to manufacture a fork which used a standard caliper, rather than one with a 57mm drop.

So I've gone for this not cheap but what is now?

What about the SPA cycles offering? https://www.spacycles.co.uk/m21b0s29p26 ... -Road-Fork

They do a carbon / alloy fork, 28mm clearance, caliper brake, that would have been one of my first ports of call:

I thought of Spa too. Would a 54mm drop work?

i appreciate that we like to upgrade and tinker with our bikes but i'm not sure that i could tell that much difference between a 28 and 25c front tyre. think the main difference (given correct inflation etc) is the look.

hope that you find a fork that works for you though

You can run a 28 on lower psi without risking damage to the rim if you hit a pot hole, so reduced road vibration is achievable with a 28.

I know it's not quite the same but couldn't you achieve that smoother rider experience by fitting a Redshift Shockstop stem? That would be simpler than changing the forks on what is a very nice bike.

you can. a bit. how noticeable this is is more dependent on which tyre you're using than size alone though.

Oh yes, of course. If road vibration is an issue, it can be worth paying for a really supple tyre construction. But even then, a 28 of the same construction will give the opportunity for a few psi less than with a 25, and I think I can feel the difference. A 23 with a big bloke riding has to be pumped up pretty hard to avoid rim damage.

About 20 years back, when I retired my Litespeed from racing duties, I want to fit larger tyres to it, but was limited by both clearance under the fork crown and between the chainstays. 25mm was about the largest that would fit. What I did was to build a set of 650B wheels, which allowed me to fit 32mm tyres - the limiting factor for how big a tyre I could fit was the way that the chainstays on Litespeed/Lynskey bikes bow inwards.

I also had to fit longer reach brakes (Tektro R556) to accommodate the 19mm smaller radius of the rims.
