Icon Air Rail OD forks (11/8) on Trek OCLV(10 posts)

Icon Air Rail OD forks (11/8) on Trek OCLVdanielc

Does anyone know the weight of this fork? I have a 2001 OCLV and want to upgrade to a fork with more rake but don't want to get a heavier fork. I've heard 150g to 600g from bike stores. I don't quite believe the 150g quote!! Thanks

150! Ha! The lightest forks on the market right now are at 350 grams. Stella Azzurra's Belagio fork I think is the lightest that is readily available.

The Icon Air Rails check in at about 550 to 600 grams with alloy steerers. The new Bontrager XXX forks are down to around 350 with an alloy steerer, but the Icon's were a bit heavier.

My frame is slightly too small for me. My toes can touch the front wheel at slow speeds. I also want to smoothen out the cornering a bit.

Unless you have clown shoes, a little toe rub is normal at slow speeds. Its more common with the geometries of small frames, since the front center dimension is smaller. Changing the rake may not make much of a difference in terms of toe rub (45 vs 43mm rake, for example). We're talking a few millimeters here.

However, changing the rake WILL affect handling. The longer the rake, the QUICKER the steering. Think about if you really want to change the rake.

What you really need is a new frameset that isn't too small.

I realize that may not be cheap, but a new all carbon fork ain't that cheap either.

mmm...i didn't realize that. i thought that by increasing the wheel base you would create a softer ride and smoother steering. but i think getting a lighter fork would be a better deal that getting a frameset plus i think i could drop the total weight by almost half a pound. any recommendations for a good fork that works well with OCLV?

thanks

There have been several posts recently about fork rake and trail and how they effect steering. Suggest you check thos out. More rake means less trail and it's the trail that helps the bike continue in a straight line and makes it feel more stable.
I replaced the Trek Icon threaded CF fork on my '98 5500 with a Reynolds Ouzo Pro all CF fork and lost 1/2 lbs. But that Trek fork had a steel steerer, and aluminum crown and lugs. Later I had a chance to change the rake from 43 to 40mm.

I should have said that a big part of the weight loss was due to changing from a quill stem to a magnesium threadless stem.

Yeah, the weight loss is deceiving...Fez

I had an Ultegra headset, Look CF fork w/ alum steerer, and quill stem. Since the fork was already on my bike, I had no idea how much it weighed.

I upgraded to Ouzo Pro full carbon fork. Expected huge weight savings, but the only thing that was lighter was my wallet, to the tune of $$$.

Here's why:

1) Ultegra headset to King headset - minimal or no weight savings
2) Threaded fork w/ AL steerer actually weighed only 420 grams. Could not believe how light it was. Reynolds Ouzo Pro fork weighed a hair under 400 grams. 20 gram savings.
3) Stem change from 3T quill to 3T Zepp threadless. Weight savings - 100 grams.

Add back the increased weight of the expansion plug and the only weight savings you have are due to the stem change. And it isn't fair to compare weights of a crappy old quill to a super lightweight threadless.

So figuratively speaking, the only thing that was lighter was my wallet.

But I am happy I did the upgrade. The Reynolds fork is great at high speeds and gives a great ride. And upgrading the stem has eliminated the annoying clicking when I would get out of the saddle.
