Collection: BMX Chainring Bolts

BMX chainring bolts secure a bolt-on chainring or spider to a compatible crank setup, and the important bit is getting the hardware length right for the parts being clamped together. Blue Groove’s range covers replacement bolt sets in different lengths and materials for BMX race and other compatible single-ring drivetrains.

Check the chainring and spider thickness, bolt length, rear-nut length and thread compatibility before ordering. Similar-looking sets can use different dimensions, so match the hardware to the existing crank and chainring setup rather than assuming any chainring bolt will fit.
