O-Rings...Where are the Damn O-Rings
I just got my FSA Gossamer Compact Mega Exo Crankset/Bottom Bracket in from UPS. The instructions say that I need to install the o-rings between the crank arms and the BB bearings. however, there are no O-Rings in the box....what do I do?
Any decent auto parts store or industrial fastener supplier should have a full selection of o-rings. You will just need to determine the size. Try the manufacturers web site, or maybe you could call.
Here is the number from their website 877-743-3372
I had the same problem with my FSA SL-K Compact. One 0-ring was missing. I contacted the seller (bought from ebay) and received a couple from him. They are very tiny things and are probably used to prevent water to sip into the frame, they are not necessary for using the cranks.
