curious what you guys typically run up front and in the back. obviously depends on terrain, conditions, and preference.
i was leaning toward 44/34 with something 12-25ish, but tonight i pretty much decided i'd like to do a 1x setup....maybe 42x11-28.
42x28 = 34x23. i could maybe even do 42x20 (=34x25).
guessing that even if we have hills they will be short, and if i can't burst over a short hill in the equivalent of 34x23, maybe i should be running anyway?
eliminating front shifting saves weight (probably not a big deal) and reduces complexity (possibly a big deal).
i'd run the single ring with catcher and guard. if i did the double i'd still use a catcher, but there's more risk of dropping a chain in that setup despite the watcher, and dropping a chain with a watcher sucks. also, there's risk of dropping the chain to the outside.
open to thoughts, but also just genuinely curious as to the choices people have made. 46/36 seems a popular setup for complete bikes that i saw when i was looking.
EDIT to add: this is mainly about CX racing or similar rides. wouldn't be doing any 30' 15% climbs or crazy descents, no using this bike in an occasional race or group ride, etc.
