Yeah, reviews report that levers like newer Shimano (more cable pull???) work a little better, but most reviews are from last year and TRP was rumored to be working on a "redesign" for the issue.
If you don't mind, are you running 140-160mm rotors (similar to what is supplied by TRP), or larger 203s?
Even with the limited miles you mentioned, any opinions on heat build-up with tandem kinetic energy?
Thanks,
