Why did Shimano use Torx chainring bolts on the Ultegra 6601 SL? And why did they feel the need to tighten them up so bastard tight without grease?
Had to get a Torx adapter for my socket wrench to undo them
Also, what's the best thing to do about a chainring guard which rubs when you switch to 1/8" chain? Stop using it and use shorter chainring bolts, directly against the spider (it's a double, with a single ring on the inside), or some kind of spacer, washer or shim?
