Jones Spec. BBS02 Steel Chainring, Spider and Ring Guard Assembly 34T 104BCD (w/4 Nuts and Bolts)

The Jones BBS02 Direct Mount Chainring and Ring Guard Assembly comes preassembled and will mount directly to a Bafang BBS02 motor without need for adapters. The 104BCD spider is specially designed and has a machined step so the chainring attaches on the backside of the spider, closer to the motor, for the best chainline. The chainring is made of steel which will last much longer than an aluminum ring and the narrow wide tooth profile keeps the chain in place.  The ring guard protects your chainring and chain. The ring guard and the spider are made from aluminum which keeps the weight down. This assembly is great as a replacement for our HD/e BBS02 complete bikes or if you are building up a frameset with a BBS02 motor.
