Post mount to flat mount caliper conversion
« on: 07 April, 2024, 05:06:35 pm »
Afternoon all

I have a mark 1 Spa Elan with cable discs, 160mm rotors and 105 11 speed shifters. The frame and fork have post mounts.

I have seen a tempting offer for 105 hydraulic shifters with flat mount calipers, so presume i will need adaptors of some sort to fit the calipers to the frame and fork, which by implication and visual assessment will move the caliper away from the frame and thus suggests I will need a larger diameter disc - how do i work out the rotor diameter i need?.

Thanks in advance

Considerably cheaper direct on AliExpress or the bay of thieves

You can use absolutely any Shimano hydraulic post mount calliper with 105 levers (e.g. BR-MT200), and they cost about the same as those adapters and new rotors.
