Thanks (thank you, thank you) for bringing attention to the the Catalyst pedal - I think it will be a godsend for me. I deal with an injury related neuropathy in my left calf muscle which prevents me from doing things like a tippy toe on that side. Had to sell my pristine manual ‘07 Honda S2000 as I could no longer use the clutch safely - a tragedy! Being able to incorporate more of my foot on the pedal will be wonderful as I half-foot my left pedal now and it is a struggle. I measure to a 76cm saddle height based on PBH, but it runs closer to 70cm in actual use. Not ideal, but better than siting on the couch.
With a new Sam ordered, I now think I will now request the smaller 170MM crank as part of the build to help balance things out. Sure glad I found this group!
