I'm planning on doing Catkills (and some other hilly RRs) and was thinking buying a long cage derailleur and 11-32 cassette might be easier/cheaper than buying a completely new crank. Plus, i'd like to have the power numbers from my Quarq to look at. It's a 130bcd so my chainring options are limited.
I have a Sram Apex Wifli RD, an 11-32 cassette and a longer chain for going out to the mountains. The 39-32 combo is equal to a 34-27. It works ok. The shifting isn't great - due in part to the cheaper quality components I am using and in part to the big gaps between the cogs on the 11-32. But it allows me to keep power when riding in the mountains.
But year, putting a compact crank on is an easier task. I just don't also have a compact SRM, nor do I really need a compact full time around here.
