AFAIK, it'll fall under the $3.5k discretionary funds rule. No, we'll use it for control cabling. It would work great.
There are ways to design around why you can shift a bike paddling up hill (actually, that's not true too - I routinely shift, both ways, going up hill. you just have to have good technique
)
A bicycle upshifts by using lifter ramps punched / machined into the chain ring. During a hard climb, chain tension will override the lifting force that these lifter ramps can generate to pop the chain from small gear to large gear (the derailer only moves the chain laterally, it cannot generate the force to lift the chain up one cog). So, the trick is you pedal faster than you would need, then drop your pedal speed while the bike is still coasting and simultaneously hit the shifter. Try it.
