She's got Skier's Thumb from a wreck last year. Wants to ride her DA STI bike, but can't shift the DA STI front lever for very long before it won't work. Spends lots of time on her aero bars resting her thumb/wrist and I think she can go a long way except for needing the front shifts. Any idea for an optimal setup for front shifting?
Rapidfire seems not to wear her out too fast, but still takes thumb pressure.
Has a grip shifter bike, good for 10 miles then her grip goes.
Any success stories? I can fit bar end, levers here or there, etc.
