So now the good stuff!
- I am really liking the new hoods!
- The shifting under load is awesome, even while powering up a climb!
- The increased brake cable pull is certainly nice.
Anyway... these are just my initial thoughts, I though I would share.
I have considered changing from 6603 to 6703 levers on our dual-disc PeriScope triple, thinking -- as you did -- that increased cable pull should make it easier to keep the discs silent, even after hard application and temporary disc warp. But I'm concerned that the TINSTAAFL principle will prevail, and that extra pad travel will cost more of the current setup's excellent power and modulation than I would like. Or that added pad travel won't make enough difference, given the narrow clearances of the calipers themselves. New 6703 levers aren't cheap, after all, and we're still saving for #2 stoker's higher education.
Now that a few weeks have passed, are your first impressions still valid? Did greater brake cable pull decrease brake rub as you expected? Have you noticed any reduction in apparent braking power or modulation?
Thanks for sharing,
Dave
