My wife has a 2015 Sirrus Carbon Comp. She has had some ergonomic issues that we have tried to address through a variety of means (swapping out parts, fitting, etc), but she still has some issues.

I am hoping that someone might have some suggestions.

Primarily, she gets back pain when going uphill, and gets hand numbness. (Her hands are comparatively small and a bit weakened from arthritis, and she has hip/back arthritis issues. Age 55).

To address these (and other) issues, I have made the following modifications:

(1) Replaced stock ass-hatchet with B17 woman's saddle

(2) Replaced handlebars with a carbon version (Easton EC70 Handlebar, High-Riser 31.8 720mm, trimmed to 650 mm).

(3) Azonic 420 flat pedals (she won't ride clip-ins)

(4) Replaced Stem with a Ritchey ±30° adjustable stem -- net effect to raise the bars and shorten the reach somewhat

(5) Replaced the 12-30T stock cassette with an 11-36T cassette (and cranked in the B-screw), primarily to make it easier on her back when climbing eg. 10% grades (our flattest local ride is 100ft of climbing per mile).

(6) Optimized positioning of Tektro brake levers -- thinking about replacing with XT for the reach adjustment knob and better braking (I already replaced the rotors with XT).

(7) Swapped out stock tires for ones that are more compliant and comfortable (120 TPI Clement Stradas).


I'm kind of at a loss for what else to try. I feel like I replaced 1/3 of the bike already.
