Campy Athena chainring moving side to side under load
Okay, so let me start by mentioning a few things:
- The frame is an All-City Mr. Pink frameset with PF30 bottom bracket (it's steel).
- I equipped the bike with a Campy Athena groupset (Power Torque crank), and installed Power Torque PF30 cups with a headset press.
- The crankset Power Torque bolt (14mm, what a MONSTER) is plenty tight.
- I checked the chainring bolts, and they're all tight too.
Now, the problem I'm having is, when I'm climbing, pedaling at a high cadence, or really just pedaling in general, I can see the chainring moving 2-3mm left to right with each pedal stroke. I can see this if I look straight down through the front derailleur while I'm riding. After reading this thread: http://www.bikeforums.net/showthread...bottom+bracket
, I am thinking of using Loc-tite on the cups. Will that get rid of the lateral movement though? Or should I maybe try getting adapters and a thread-in bottom bracket? Is the problem that it's a steel frame?
Any ideas would be great.
