My first post so apologies if its been asked before!! I have a Cervelo RS 2008 and have just swapped the chainset from a FSA Team Issue and fitted a SRAM Red Chainset with Sram GXP bottom bracket. The problem is there is slight play in the crank arms when moved laterally. Do i need a spacer/ washer or does the BB need facing off?

Cheers Johnny Boy

    Grease the spindle put the left hand crank on then tighten until the slack is gone it sounds wrong but that is the way

    +1 on the above advice.


    Sram actually recommend taking the crank arm off if there is play, greasing the bearings and re-installing until the play is gone.

    I use Red on my bike, but it's a Trek with press-in bearings so a little different - but I have to tighten the crap out of the cranks to get them tight - WAY past Sram's recommended torque levels.

    Just (obviously) be careful in your case not to damage the BBN cups.

    I personally would tighten the arm slowly until it feels tight. Go for a ride and see if it loosens up a bit and then tighten slightly again - and it it stays tight - you're golden.

    Hi, Thanks for the advice:)
    I have tightened up the left hand crank arm with a longer allen key, it does take some elbow grease before the slack has gone.
    Cheers
    John :D
