    SRAM GXP BB and Crank Installation Question

    Hey all.

    I'm building up a couple 29ers for my upcoming tour of the GDMBR. I just installed both x7 cranksets and feel like they weren't installed quite right. My question is this, how far should the drive side spindle be inserted into the BB? I took a photo of the instructions that came with the crankset, and circled the area in question. Click the first link for reference. I'm wondering if the circled area should be visible when the crank is installed. Right now it is, on both bikes, and the crank bolt is secured nice and tight. I took a couple more (somewhat abstract) photos to highlight the area.

    Any tips?

    Just built up my 29 with same crank gear. Looks just the same as yours. Also had the same question and wasn't sure if I had assembled it correctly. May take it in to my LBS just for them to check it out. Checked that the inside of the crank arms were the same distance from centre of down tube. Right crank was slightly (50 thou) further out than the left.

    But as we seem to have the same outcome maybe we got it correct
