How Is Chainring Bolt Length Measured?
23 Jan 2015
Does one measure the entire bolt length or just the threaded portion under the head to the end of the bolt. I'm looking for a bolt with a thread length of 9mm to fit a 30tooth raceface narrow/wide ring to the outer fitting of a shimano 2x10 xt crank.

many thanks

The length is measured from the inside of the head to the end of the thread. For the fitting of a 30T N/W ring from Race Face the information provided by Race Face suggests an 8.5mm bolt will be sufficient, this is the standard length for chainring bolts that pass through two chainrings, the Race Face set is SJSC part number 27177.
