Make much difference? Particularly interested if using one on a steel frame. Weight can be significantly saved by using carbon but any other considerations?

Flex. A lot of modern cross forks seem to be very badly affected by brake judder. Tediously my Argon 18 suddenly seems to have developed it today after 18 months of not doing it.

Probably a sign that your brake blocks have worn flat; mine did the same a week after the 3 Peaks, need to toe them in again.

Yup - was actually thinking that on my ride into work.
This year's 3PCX was grim - I haven't really ridden since seeing as I have a ulnar collateral ligament injury from a fall at the foot of the first climb (doh).

So judder not an inherent issue?..

Not generally with my argon 18, but with my previous frame using Easton EC70 forks it was very intrusive - to the point that the front wheel would come off the ground on heavy braking.

carbon likely to be stiffer. Shame there's no light steel forks around anymore ๐Ÿ™

Brant?

All the people racing this weekend who had steel frames had carbon forks.

and seatposts? People go on about

a) how compliant steel is,
and
b) how Ti and Carbon seatposts are great because they have more give in them that alloy.

Following that, steel posts should be a staple. Or is it all a load of bow lakes?

I can see stiffness being more of an issue with forks, though. No-one likes brakes rub and flutter. beef up to avoid that, and I guess you've got a heavy fork.

No excuse for the seatposts, though!

The judder is probably caused by the brake hanger being fixed the the headset rather than the forks. A common CX problem fixed by a fork mounted hanger.

You can bend steel forks back after a "moment' ๐Ÿ˜ณ

SD why not try them?

Steel seatposts...making the clamp in steel is heavy and expensive...in alu is dodgy.

Swedish chef did you think about the availability of light steel forks?

Cynic-al; Could be possible to get somebody to make a light steel fork?

I guess Nigel Wilson or Chas Roberts could make some or Dave Yates.

Maybe...at a cost tho.

Yes, probably certainly at a cost.

If you mentally spread the cost over the next couple of years, and looked at it in monthly segments though, and remember you'd only spend the money on forks once, it starts to look justifiable. ๐Ÿ™‚

I like your thinking. Do you have lovely bikes and a load of debt? ๐Ÿ˜‰

I had a carbon fork on my Genesis Day One CX ss tester bike - same as the Cotic x, Voodoo, Ridgeback and other's fork - and found the steel one that was specced for production more comfortable. But it was heavier.

Problem is, comfort in a fork means flex and that flex isn't so good for control or under hard braking, although 'hard' braking on a cx bike is relative..

I know it's not rational but I rode the bike harder on the steel fork. Something very reassuring about a steel F+F.

I use a carbon frame and forks, however out of the the 5 people I know who race on steel frames, 4 of them use Easton carbon forks. The other uses the steel ones which came with his very nice Gunnar.

What do light steel forks come in at, 700grams?

Saladoger - if you go down the carbon route I'd be interested in the P2's (if they're 700c). Having splurged on a Kona Sutra frame in the CRC sale I need the forks now.

Don't know if Independent Fabrications sell their steel cross for separately.

Hmm I use steel forks on my Gunnar steel cross bike, much nicer ride and no brake judder either and all in build with Veloce is under 19lbs.

They are nice those Guunars, the same guy has one of their MTB's as well in the same light blue colour, lovely.

Yeah my Gunnar is Sweet, bettered by my custom Waterford, but that's a road bike! I will at some point upgrade the cross to Chorus or maybe Ultegra/dura ace, want to get it under 18lbs ๐Ÿ˜€
