My bike is in the shop for a few weeks so I'm borrowing a ride from my son. This is, obviously, a good thing. The bad news is that prior to his crash last year he was Cat 2 so his "climbing" gearing is 53-39 and 12-28. My gearing is 53-39-30 and 12-27. OTOH, I'm going to feel like a real macho senior citizen for these few weeks
My only other option is to ride our tandem solo with it's ultra low gearing, but riding a tandem solo, while perfectly safe, is a bit twitchy. Normally, I would use this situation as an excuse to buy a backup bike, maybe a mountain bike, but we've got some home improvement things going on and thereby consuming $'s. I'll just have to HTFU.
