I rode 61.8 miles this week. I think I’m leaving the stem on the Trek in it’s new, lower position. I am still debating a longer crankset, a seatpost with more setback, or both.I’ve been reading some of the strange formulae that are supposed to tell you what length crankarms you need, and mine comes out to something between 186mm and 200mm. (I have a 20″ femur and wear a US size 15 shoe!) Of course, nobody makes crankarms in this length unless they’re ‘custom’, so I don’t know if it’d be worth the money or not. For my purposes, probably not.
