Started off riding triples in my late 40's. As I've gotten stronger, I've migrated to standard doubles.
The road bike has a 53/39 up front. Came stock with 12-25, but I sometimes put on a 12-27 if there's going to be a lot of climbing (e.g., the
Death Ride).
The TT bike has 53/39 up front, with 11-23 cassette.
I'm currently building up a Surly Long Haul Trucker frame for around town, errands, commuting, and possibly loaded touring. It will initially be set up with a 9 speed Ultegra triple (52-42-30, with 11-23 cassette).
