Narrow-wide single chainring, for 8-9-10-11sp chains
Description
This low-gear narrow-wide chainring allows you to use a single front chainring with up to 11 cogs on the rear. It'll fit 110mm BCD cranksets (common for compact road, cyclocross, and touring cranks), we've made a few over the years and they're pretty common kicking around the bike world.
The alternating-width tooth pattern serves as chain retention but is still best used with a "one-by" specific clutched rear derailer.
For 3/32" chains (8-thru-11 speed)
BCD 110mm
38-tooth
