Creak from 105 5700 Crankset - Lube Crank Spindle?

Hello everyone.

After about 5 years of heavy use my Specialized Roubaix developed a creak.

I've changed the BB (which was worn out), slathering the cup threads with anti-seize. I've tried riding with regular shoes to rule out my road shoes / cleats. I've taken off both pedals, removed their spindles, cleaned inside the bodies, filled the bodies with fresh grease and pushed the old grease out, then reinstalled the pedals with lubricated threads.

The creak is still there and hasn't even changed. I'm going to remove the left crank and reinstall the pinch bolts using a torque wrench - I didn't have one last time. Maybe this will help. While I'm at it, should I lube the spindle this crank fits over? I thought square taper cranks were not supposed to be lubed, so I didn't lube here last time. If one of these things doesn't do it I'm out of ideas.

Unless I had the pre-load cap too tight, though I can't see that being the problem. Any ideas?

Bikes: Too many. Cannondale SuperSix, Trek Remedy 8, Trek Crossrip+ get the most ride time.

You should grease the spindle of a hollowtech ii crank, though my gut is that isn't the cause of your creak.

Maybe remove, lube and torque the chainring bolts. Check your saddle.

I didn't think about the chainring bolts. Thanks! I'll try that too.

+1... beat me to it... that's the one thing not mentioned by the OP...

It was the left crank/spindle interface after all. I pulled out the cap, pinch bolts, and crank, wiped everything down, and reinstalled, putting waterproof grease on the spindle and pinch bolts and evenly torquing the bolts.

It's dead silent now. I can't remember the bike ever being so quiet and smooth before. I should keep up with maintenance more often!

I also noticed my Park tool for the cap has a 8mm hex fitting, so it could be used with the torque wrench next time. Nice feature!
