GXP Installation, Single Speed Problem

I picked up a Ridley Ignite Singlespeed Frame, with track ends and disc mount, and am having trouble installing a Truvatuv Stylo, singlespeed crankset on it.

I installed the GXP MTB bottom bracket, with an included spacer on each side (since BB shell width is 68mm), but when I put the crank spindle through, the drive side crank (race?) is still about 3mm from pressing against the bearing seal. Even when I tighten down the non-drive side crank arm, the drive side is far from laying flush against the bb.

I have installed Truvativ Omnium track cranks on bikes before without a problem. The drive side crank always rested on the drive side bearing cup...

I can't imagine that Truvativ would have the drive side crank floating, not pressing against the drive side bearing.

What am I doing wrong?

Thanks!

The drive side cup should not bottom out on the frame, I think. Is it 113 or 118? you may need a 113 if you got the 118

Sorry, I am no help at all. Don't even know why I replied

You're supposed to have 2 spacers on the drive side and one on the non drive side. (unless you want to move it to the left to shore up the chain line a bit. There are supposed to be 3 spacers total. Each are 2.5mm thick.

GXP is external, not internal, there's no set spindle length. Only set spindle length with an external with a set spindle length is the howitzer bb.

Did you have the spacers correct; 2 on drive side, one on the non drive side?

Something tells me he left one out.

Awesome! I didn't realize that I was supposed to use three spacers total. The BB only came with two, and the manual said to use one on each side for 68mm shells.

Your LBS should be able to slide you one.

If not, PM me and I'll check my toolbox.
