I think I am going to switch from FSA rings to Dura Ace.

Also after doing Devil Mountain Double on the tandem for the 2nd time last weekend. I am ready to put the 28t Salsa granny ring back on. 50-60 cadence for literally a couple hours if you add up the time spent on the steeper grades. Will probably go with a 39t middle again so that we can leave in in the middle ring for most climbs, and even the spread to the 28t.... TDB.
