    New question here. Stylo SS crank installation question.....

    I have searched the posts, and can't quite find the answer to this question/ issue:

    For those of you that have the Stylo GXP SS crank, when you install it, should the drive side crank touch the BB cup on that side? I installed myne to the torque specs, but the driveside crank did not slide all the way in against the BB shell like I would expect to see.. You can see a small section of the axle still sticking out.. Is this ok/right, or do i need to dissasemble, re grease, and do it over again? I have heard you need to be very careful installing these, I can see why!

    Thanks!!!!

    Did you use the black spacers? Manufacturers BB shell widths may vary a little. The emphasis on proper torque is to ensure you don't pre-load the bearings too much and destroy them early. Stylo's are a good crankset and the GXP bottom bracket will last if properly set up.

    Here's what my setup looks like on my Karate Monkey.

    Thanks for the response...I have a 73mm shell, so I do not need to/are not supposed to use the spacers.... It seems to me like the axle is getting stuck on the driveside somehow.... It will not slide all the way through.. It looks like it is touching the inside of the crank to me in your photo? I don't have a camera handy, but you can see the silver from the axle of the crank sticking out about 3 or 4 mm?.... Does that make sense? I guess I should back everything out and re grease?

    here are a couple of photos....

    Hope this helps... The cranks don't wobble, but there is defintely a space there that looks like it should not be there...?


    yeah, i know, nice P.J.s..

    It's fine. The driveside bearing just floats with the Truvativ design. The preload is done with the non-driveside. The drive shaft steps down in diameter to slide through the bearing. Torquing the arm on to spec is doing the preload. As long as that's done to spec everything is fine. The biggest issues that occurs with these cranks are the bearings tend to go out faster than other outboard designs and the arm tends to loosen. I haven't had any problems with the latter once I put an actual torque wrench on it.

    Great, that's all I needed to hear. I did put a torque wrench on it, but it does seem tight to me, the black seal on the non drive side spins along with the crank, guess that's normal too...?
    Thanks all!

    I haven't had any of the bearing issues - the BB on my pics above have been on 3 different bikes dating back to 2007. They even have a dent from a sizeable rock that schwacked the lip while flying down the rocky double track at Oak Mountain.
