I love it that the op is exploring his shifter options 24hrs after cutting off his thumb!! Slowtwitch Hall of Fame right there!
Seriously, I can't believe you are the first person to mention this. How HTFU is that? Awesome.
No shit. And such a nonchalant thread title... "Yeah, so anyway, I was just trimming up my aerobar extensions with this here bandsaw, and the darn thing slips and there goes my thumb. Now I gotta see if the ER can rig a watertight dressing so I can make masters practice tomorrow morning."
If Apple could just figure out how to rig an iBeer auto-pay system, I'd buy you a cold one right now!
And the OP will have to shorten the aero bar too, to get the thumb stub to be able to reach!
(don't ya love the caring, concerned people here on ST? It IS all about the bike! LOL)
FWIW, after I had my bone graft and arterial transplant in my wrist, I asked for a waterproof cast so I could still cycle commute to work, THEN get to swim squad. Apparently the look on the surgeons face meant no swimming or riding for a while. Pussy! :-)
