Sold and shipped by Sport & Go EU
Made at USA from machined 7075 aluminum, the RENNEN crown is unique thanks to the decimal gearing created by a slight modification of the crown's circumference. This allows you to modify your gear ratio by a fraction of a tooth, according to your needs for the BMX track you'll be riding on. It is designed to be mounted on a 4-screw crankset. What's more, this version integrates the clamping screw nuts directly machined into the sprocket, eliminating the need for a wrench to screw your sprocket to your crankset. FEATURES:
