What is the correct disk size using included IS bracket?

By Tom

28 Jun 2023

With IS mounts will these calipers require 140mm disk rotors?

My bike currently has Clarks M2 disk hyraulics with 160mm rotors.

Thanks

SJS Customer Service:

Without adaptors direct to the frame the calliper will take a 140mm rotor, 160mm with an adaptor. SK 29/06/23

Shifter compatability

Sorry to bother you - is there any way you could confirm that this caliper would work with an ST-4720-L shifter?

I'm building a bike with IS mount on the rear. I've purchased a tiagra 4700 disc groupset which includes BR4770-R brake calipers. I plan to use this product instead on the rear with IS to PM adapter.

Thank you!

SJS Customer Service:

Hi, sorry we can not confirm this caliper will work with Tiagra 4700 levers. Shimano normally list cross compatible parts, this combination is not listed. Thanks

Post mount adaptor?

By Neil Aberdeen

26 Oct 2017

Says - "Front or rear wheel use for International Standard or Post mount with adapters (not included)"

Does this mean I need an adaptor for (front) post mount?

SJS Customer Service:

Hi,

This brake has a post mount fitting as standard so it will depend on the size of disc rotor you are using and what size rotor your forks are initially designed for to whether or not you need to fit an adaptor.

Thanks.
