I just bought a used 07 Tarmac SL with the same crankset (yeay!). On the first long-ish ride (of course not on the testride before I bought it...) I noticed a little bit of creaking when I hammered hard on the non-drive side crank - not noticeable on the drive side crank. On closer inspection, I did the same check-the-torque-by-hand test that Cartmaniac did, and the bolt is on plenty tight, yet I too can notice a little bit of play on that left-side bearing when I grab the crank arm by hand and try to wiggle it towards/away-from the frame. The previous owner said that he only had about 1000 miles on the bike, and it *looks* it (of course how do you know for sure?), yet I would be surprised if those bearings would be worn out that quickly... Any others have any feedback on this? Could it be anything else besides the bearings being worn? Thanks!
