first brevet last year was on a triple crank, second brevet last month was on a compact 50/34 with 11-28t. my asthma kicked in on the second brevet near the end, and of course before a big climb. i struggled to stay upright and could pretty much only breathe deeply enough for my HR to be around 130-140 (normally i would probably be around 180bpm and be trucking much steadier).

just spruced up my triple crank bike for this year. i'm subscribing to the 'better to have it and not need it' camp for sure.
