I just got Exustar shoes and Shimano SPD-SL pedals with SM-SH11 cleats. Problem is, the cleat fixing bolts that were included with the cleats aren't long enough to bolt to the shoes. I'm wondering what length of bolt will work best for this? I'm seeing a lot of "extra long 13.5mm bolts" online- would they be long enough to bolt to Exustar shoes?
Any help greatly appreciated, thanks!!
