• Bike has developed a creak from the drivetrain (I'm guessing cranks) that generally only happens once at the start of my rides when accelerating for the first time. Bike then generally stays quiet for the rest of my commute. I do skid to brake and stand on pedals to accelerate from lights, but I haven't taken it up big hills to put massive torque on the drivetrain yet to see if it would reoccur mid-ride. I then discover that I can re-tighten the cranks (just a little) so I'm guessing cranks are coming ever so slightly loose; not sure if the answer is that I need to just put more torque when tightening the crank? Slightly worried about overtightening; have a 20cmish-long 8mm wrench and feel like I'm putting quite a lot of pressure into it when tightening the cranks as it is (I put it parallel to the ground, brace myself against the saddle and pull upwards) but no torque wrench to know for sure (it's on the shopping list but those things are not cheap).

  • Borrow a torque wrench.

    Can you recreate the sound by standing on a single pedal with bike against wall? Or moving cranks side to side to check play. Can also try standing on crank arms to eliminate pedals and can check wheel by leaving feet off pedals and/or isolating it from chain, etc.

    Clean and lube everything properly too.

  • Chainring bolts all tight, pedal bolts tight as hell, no play from cranks and standing on pedal at 6oclock on both sides and bouncing for a bit creates no sound. What in the wheel might cause a click? Generally the click only happens once at a start of a ride and then I don't tend to hear it after.

    The chain is lubed and is generally silent; what else needs lubing?
