For SRAM GXP/ISIS2 Cranks
SAFETY INFORMATION - READ BEFORE RIDE
Since specific tools and experience are necessary for proper installation, it is recommended that the
product be installed by a qualified bicycle technician.
Read the service instructions of your crank carefully prior to installing the parts. Loose, worn or damaged parts may
cause riding problems and serious injury may occur as a result. If installation and adjustments are not carried out
correctly, the chain may come off and this may cause you to fall off the bicycle which could result in serious injury.
Read these instructions carefully, and keep them for later use.
Ensure that the frame BB shell is clean, and on BB30 frames the cir-clips/bearings removed.
•
• Make sure the black O-ring is on the Non-Drive Cup prior to pressing into Non-Drive side.
• Apply Anti-Seize to the drive cup threads before installing.
• Before riding the bicycle, check that there is no play or looseness in the bottom bracket connection. Also, be sure
to retighten the crank arms and pedals at periodic intervals.
• If you feel any looseness or 'play' in the bearings, the bottom bracket should be inspected/replaced.
• Be sure to read the instructions for your front chainrings/crank in conjunction with these service instructions.
• Do not wash the bottom bracket with high-pressure jets of water.

professional bicycle dealer or call Praxis Works.
