I've been experiencing a creaking noise (similar to if your crank bolts aren't tight enough) from the cranks/BB area, but I'm at a loss as to what it could be. I just tore the entire thing apart, re-greased (bolts and all), and torqued as hard as I could, but I'm still creaking along. The cranks are shimano ultegra road doubles attached to a shimano octa-link BB and I worried that something may be wrong with the set-up as I had no un-explainable creaking with my shimano 105's & UN BB. I've had friends run octa-link stuff on fixed gears before with no problem and I'd like to have my super-stealth IROSE back up to speed. Any ideas?
