Hi Guys,

Hoping you guys could help answer a question for me. I have a 2011 Trek Fuel EX 9.9 and I installed an FSA K Force Light crank when I tightened the crank bolt to the recommended torque the crank arms spin seemed tight. I can still pedal them but it seems pretty inefficient.

When I don't tighten the the bolt to the recommended torque the bolt kept falling off. I tried loctite but the bolt continued to fall off even after the loctite dried.

Any advice?

Thanks in advance
Chris
