Hey i just got a new RockShox Revelation and im trying to install it on my bike. I know a decent amount about bike building but i havent dealt with new forks much.

The fork i have is a 1 1/8 headtube but it has a pretty big bulge at the bottom like 1/4 to 1/2 inch long and i cant get the crown race to go over it and im afraid if i force it its going to break my thin little cane creek s3 crown race.

Heres a picture of the fork and you can see the spot im talking about

do you know if you bought a tapered tube one ... from 1.125" to 1.5" ?

I checked the Sram site for that fork but didnt see it offered in a tapered steerer tube ... so my guess is you just need to tap it on with a piece of 1.25" pvc and put a little grease on the tube first

work the race down by hand as far as possible and make sure it is not cockeyed, find a pvc pipe thats a close fit, place an old crown race on top of the new one a tap it in to place, it should go.....best way is to have the proper tool? if you can afford.my method worked well on an old rockshox psylo and my new recon 351

I use the 1-1/4" schedule 40 (thick wall) PVC pipe to drive on crown races. No need to use anything between the pipe and race. The plastic does no harm to the race. I would be afraid adding the old race would jam it onto the steerer.

its never been an issue:) as I can tap it back up...carefully with a plastic shim, I find the race to be a more even surface...either way would work I guess.

Just adds a couple extra steps. If the end of your pipe is uneven the second race does not change that. I use the factory cut end and rotate it as I drive the race home.

or ask your lbs to do it. if you walked into my shop with a fork that just needed the lower race pressed on, i'd just do it for you and send you on your way. might take me 30 seconds.
