    Default Fork Rack on CX Bike

    Hello All,

    I finally have something to post about that is relevant to the skilled folk on this forum. I know this topic has been discussed elsewhere, but I wanted some expert input since my scenario is little different.

    I'm looking to purchase a carbon CX fork for my custom steel cx bike. I had the frame built with the intent of being my do all bike, some trails, fire roads and occasional cx race. The builder (True North) delivered exactly what I asked for in an amazing bike. I've since found I do more cx racing and training on it than trails and so I would like to lighten it up a bit with the addition of a carbon fork.

    My concern is the impact a rake change might have, judging by the CAD I think the rake is 445.7mm.

    What sort of rake should I look for if I want this bike to handle more nimbly (less like a MTB) given it was built on the monster cross tip. I run it SS with standard cx tires.

    Thanks for your thoughts...

    Actually from the drawing, it looks like fork rake on your bike is 50.0mm. See below.

    Thanks, 50mm would sound more reasonable. So correct me if I'm wrong, if I were to install a fork with 44mm offset, this would shorten the wheelbase and result in improved handling and more toe overlap.

    Is there a quick check, based on geom, to know if I'll be creating something unmanageable by decreasing rake this greatly?

    It would shorten the handling and create the possibility of toe overlap, but whether it would improve handling or not is more than I can answer. Hopefully someone else will chime in here.

    Do you like metal and whiskey?

    On topic: Less rake=more trail so it would theoretically make it the stering feel heavier at slow speeds steadier at cruising speed. In reality though, 6mm isn't much of a change and if the new fork is the same length and you use the same tires, you'll soon adapt to the different sensations and you won't notice any difference from the trail change.

    Less toe clearance, or the "carbon feel", however...that you will always notice. Can't say if that's a positive or negative thing for you.

    Indeed and sometimes at the same time...

    Thanks all for the input...makes sense. I do dig the current fork, especially on the nasty stuff, but I'm thinking the addition of the carbon fork with less rake mike make navigating tight switchbacks a little easier. Here's the finished product from True North 390143_10150392519586573_523301572_8780313_237382369_n.jpg

    If you want more "nimble" steering, you want MORE fork rake, not less.

    From the spec sheet you provided, you've got 50mm of rake. I think you'll be hard pressed to find a carbon 'cross fork with more rake than that.

    My experience is, a 3mm difference in rake is so subtle it's almost not worth the money. 5mm, and you feel the difference.

    Good luck finding a 55mm raked 'cross fork.
