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.

42x11>44x12.
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.

I have a 46/36 and an 11-28 on mine. It seems to work well for me. I've never felt the need more or less. I've contemplated going down to a 1x setup, but haven't really investigated it much.

A teammate who is consistently in the top 20 nationally runs 1x10 with 42 front and 11-25.  Caveat: he is a very strong, low-cadence masher (I guess that's probably obvious).

The thing about cross is that you never know what you're going to get with the next course, and conditions are constantly changing. One lap it might be best to power up a hill, the next lap it might be better to run. Unless you're a masher like GC's friend, I would be much more interested in flexibility than weight. A double chainring setup gives you that.

I run a 36/46 and an 11-25, although I'm switching to an 11-28. I do not race it, and I regularly haul 20+ pounds of stuff on it, so I need the gears.

Something to keep in mind with CX gear selection is that generally speaking traction is poor/nonexistent.  Big gears help keep the wheel biting on a muddy slope.
