Hi all,

I have just bought a charge cooker 29er frameset, and looking to buy a set of rigid forks.

What size fork (axle to crown) would I need to replicate a 100mm travel suspension fork to maintain the correct geometry?!

Any help greatly appreciated!

Thanks,

Mike

    Somewhere about 450mm A2C should suite.

    I'd imagine it would be close to 470m for a 29er. Best thing to do is simply measuer from the center of the axle to the bottom of the frames steerer tube and deduct 20mm to compensate for sag.

    On-One's monococque rigid fork is quoted as 470mm axle to crown, and is also stated to be equivalent to a 100mm suspension fork on a 29er. It's also reasonably priced and very strong - I've had no issues with mine
