Outer Bolts?
30 Jan 2015
Hi, I was looking around, but could not find the outer/ female part for those bolts. I'm also wondering if they are actually made of stainless steel because the description states that they are made from 7075 T6 bar, which usually is aluminium.
SJS Customer Service:

Our description was previously incorrect, these are definitely steel. These do not have an outer/female part as they are designed to be used with an inner ring on a triple chainset, these bolts are designed to thread directly into the crank arms themselves.
