CX 70 (shimano ultegra cantis), Tiagra 4400 levers (no shifting) and the cables they came with are good. The lever is very similar to old tricolor 600 levers.

Installing took a while to get my head around but it wasn't very hard.

They squeeled for a while. Now they squeal occasionally, but they've bedded in and are mostly silent.

Power/ feel is very good.

They are night and day different, especially to adjust, to the 80s dia compe cantis with kool stops on my old touring frame.

The reasonably narrow profile is nice, and cantis that extend past your racks would be annoying.

Clearance is good, but adjusted to sit close to the A719 rims on my gunnar, i can't quite release the brake cable, so i have to deflate the tires to remove the wheel. This sucks big time.

These are wide (23.5 mm) rims, and with narrower rims i think it would be fine, but it's annoying.

Overall its a very good system.
