    Bob Jackson Vigorelli - What crank length do you use?

    I have a Bob Jackson Vigorelli on order which I'll be using as a fixed gear commuter and Im not sure what crank length to order. Id like to use 175mm but Im concerned about pedal strike. (My roadbike has 175mm cranks so Im used to them.)

    Tyres will be 700 x 25 Gatorskins.

    Pedals will be Crank Bros Eggbeaters.

    Frame size will be 24.5 C-T.

    Questions.
    If theres anybody out there with a BobJ Vigorelli, what crank length do you use? Do you have any issues with pedal strike?

    Thanks for your help.
    P
    Don't have one yet. Still waiting for inspiration.

    If you use the search function here, you will find out that BJ Vigorelli has really high bottom bracket, so you probably won't have any problems using 175mm cranks, especially with clipless pedals.

    I don't have one myself but IMHO Vigorellis are very nice, BTW.

    I have a 20.5" (~52cm) vigorelli and I'm running 165mm Sugino 75 cranks. There's plenty of room, so I don't think 175 will be a problem.

    What is the rake and trail on your fork? Everyone I've talked to with an off the peg Vig has been pretty unhappy with how the front end reacts.

    i forget exactly but when i emailed them a few years ago the geometry was like a regular road bike but with a steeper seat tube angle. head angle was something like 73.5 and rake was like 40mm.
    so i ordered a custom one, specified steep head angle and short rake and still ended up with a fork with alot of rake....
    i sold that frameset.
    help.

    Your story is pretty common from what I've read. I really wanted a Jackson until I kept running across similar things.

    yeah. i'd only consider a used bob jackson at this point. not having them build me anything again.
    i'd maybe ride one of their touring bikes.
    wouldn't ride a new BJ track bike because they don't ride the way i like. if i wanted relaxed head angle and big rake then yeah, but i don't really like that feel.
    help.

    the vigorelli are not of a tight geometry - it's a grass track bike with plenty of clearance. more like a relaxed or a near road geometry which makes for a comfortable ride, but not "track" in a common way (not twitchy, nimble, or tight), so if thats what you're looking for it's probably not for you.

    Why do people have a conception that "track" geometry is twitchy? It just plain isn't. Have you ever ridden a crit bike?
