If you're experiencing bearing play in your Trek Bicycle's GXP crank or bottom bracket assembly, start by ensuring the crank has been tightened to the specified torque. Many play issues are resolved this way. If the problem persists, try adding a 0.5 mm washer/spacer (PN 294162) between the wave washer and seal to increase the bearing preload.
What to do if the spline of my Trek Speed Concept 2014 Bicycle GXP crankarm is undersized?
If the spline of your Trek Bicycle's GXP crankarm is undersized, remove the crankarm, apply plenty of grease, and reinstall it. Make sure to tighten the crank to the specified torque. After installation, re-check the bearings. The GXP axle spline is tapered, so the crank must be fully tightened to seat correctly on the axle.
