I've got a couple big rides coming up, including the Kettle Crest in NE WA (43mi, ~11k elevation gain) and would like a bailout gear. I'm on a 30x42 small gear right now and it's not enough for these big rides when I'm gassed.
Any of you pedal mashers have a spare weenie cassette out there? Prefer HG but could make XD work too.
