Well, I know "normal" cross levers are short pull, for caliper/cantilever brakes, and then you get some that are long pull for V-brakes like the Paul Love Lever. I was just wondering if the changes to the Shimano caliper brakes would cause problems with a normal short-pull cross lever.
On my everyday fixed bike I have a Shimano R650 with a Tektro RL726 alone (no drop levers) and it works a treat - loads of stopping power. I'm planning a nicer project bike and I'd been thinking of using an Ultegra 6700 or DA 7900 front brake, which is when I saw this in the description:
"Dual-pivot caliper brake with super SLR design for quick linear response, increased rigidity and improved braking power and must be used in conjunction with 7900 or 6700 STIs for correct leverage ratio."
And that's what got me wondering. I know they've changed the amount of cable the new shifters pull (to make little ring to big ring shifts easier), and at the same time they've changed the lever pivot to make the brakes easier to use on the hoods, so I guess the latter change might have something to do with it. There's probably not going to be much in it, is there?
I might go for a 6600 SL anyway, depending on what colour the bike ends up...
