I bought a 2011 specialized tarmac sl3 s-works about 2 month ago. That bike came with the specialized fact carbon crank set. I have been having an issue that the chain fall to the out side of the crank when I get up and sprint or just accelerate quickly. I want to know if anyone out there is having this same issue with the specialized crank set.
If you could post your comments I will greatly appreciated.
