They went on m missus HT fine the 1200mm hose was OK on a 15″ frame.
The front hose @700mm though was slightly too short, so I,m swapping it for the old but very similar M525 off of my SS as the hose on that is a bit longer and she’ll not actually notice the difference. With the shorter A-C rigid fork on the SS I won’t have any issues.
Swapping the hoses takes minutes, I’ve not bothered to re-bleed them, doubt I will for a while TBH, and the rear came with an ISO adapter which was not needed, but nice to have.
Basically they’re about the same as the old M525 (same pads too I think) which was a pretty reliable simple brake.
