i've converted an older 7 speed Trek 7000 MTB to a commuter and have replaced the BB, chain, pedals, and cassette already. the chain ring is a triple Shimano SG C-46 and is next on the list to replace. since my commute is relatively flat, i ride exclusively in the largest chain ring and shift only between the 3 smallest gears on the cassette.

can i go with a single or double chain ring? what would be an easy drop-in replacement?

i'm a noob.

Thanks!
