A strong 7
I noticed a layer of rust forming on the bolts that hold the chainring, headset, etc. I keep my bike in the garage, and didn't realize that there was that much of a moisture issue there to cause such a problem. That being said, I'd like to replace these bolts with Al or Ti. Is there a "standard" size for these bolts, or do i need to contact the manufaturers of the original parts to get the bolt size.
