Our take on the BR-R9170 Caliper Fixing Bolt C for 20 mm Rear Mount Thickness

This is a single Shimano fixing bolt for flat-mount disc brake calipers, sized for a 20 mm rear frame mount thickness. It is a genuine replacement part for Dura-Ace R9170 and other flat-mount Shimano calipers, not an upgrade. Riders buy it after losing a bolt, swapping frames, or fitting a caliper to a frame with a 20 mm rear mounting face. It does one narrow job, and third-party bolt kits are cheaper but vary in thread quality and head fit.

Questions and answers

What does the 20 mm refer to?
It is the thickness of the frame's rear flat-mount face the caliper bolts to. Measure your frame's mount before ordering; a different thickness needs a different bolt length.
Which calipers does it fit?
It is made for Shimano flat-mount road calipers, including the BR-R9170. Check your caliper model and mount type before buying.
How many bolts come with it?
One bolt. A caliper needs two, so order the quantity your setup requires.
Can I use a generic hardware-store bolt instead?
It can work if the thread, length and head match, but bicycle brake bolts are specified for the caliper's torque and clearance. A mismatched bolt risks a loose caliper.
Do I need threadlocker?
Shimano caliper bolts are typically fitted with a threadlocking compound and torqued to spec. Follow the caliper's installation instructions.
