DESCRIPTION
ROLLCii 1X Chainring 38T, BCD104 4-Bolt, 7075-T6 Aluminum, Polish Silver
Part of Veloci Cycle's ROLLCii precision-parts line, this is a dedicated 1x narrow-wide chainring built for 104mm BCD, 4-bolt crank spiders — a straightforward way to convert an older mountain bike drivetrain to a simpler, more reliable 1x setup. CNC machined from a 4mm-thick 7075-T6 aluminum plate, it's non-directional and mounts to either side of the spider.
The narrow-wide tooth profile keeps the chain seated over rough terrain, and it's compatible with most 9 to 12-speed chains across brands, so it drops onto most existing 1x or converted drivetrains without a special chain.
