Recently replaced a set of leaking Shimano m445’s with some Clark’s Skeletals from CRC, they were about £62 for a complete set of levers, callipers and discs and they came with IS mounts and two sets of sintered pads.
Seem to be working OK, had a bit of messy around as I went for the biggest available discs and then needed a post mount (wasn’t clear that they would be IS mounts) and they provide a 185mm disc for the rear not 180mm meaning I needed a couple of washes to get everything fitted.
Nice and powerful, don’t squeal like the Shimano had for the past 12 months due to the leak. Happy with them so far.
