BBB ROADGEAR BCR-12S

Chainrings

We have BBB chainrings compatible with all 5-arm road cranksets (RoadGear), and 5-arm and 4-arm MTB cranksets RoundAbout). CompactGear chainrings are designed for compact cranksets. Unusually, even the BBB small chainrings are CNC-machined from 7075 T6 aluminum providing all of the advantages of steel combined with the corrosion resistance and incredible weight savings offered by aluminum.
