I've inhearited an older OS 120 Surpass and in the process of cleaning and installing new bearings. I installed a new main bearing, as the front one form Team Fast Eddy was too small. And it seems like the crank will go too far forward with the main bearing installed. Is the front bearing supposed to keep the crank from moving forward? Or is there some thing I'm missing? Thanks.

Found the issue. The Fast Eddy Bearing Kit! The rear, or main bearing is the wrong size as well. The kit came with an 8mm thick rear, or main bearing, and it needs to be a 9mm thick bearing.
