Improve your hill-climbing ability with a smaller chainring! Its narrow-wide tooth pattern prevents chain derailment and increases longevity. The rings are crafted with CNC-machined 7075 aluminum for unmatched precision and durability.
Available with 30T for the BBS02 and 30T and 42T for the BBSHD. Spacers are available to adjust the chain-line as needed.
CanadaThe 42t Biktrix narrow-wide sprocket has been working perfectly, no need for a chain guide. I have one on my BBSHD 1000w fat bike and a full suspension mountain bike. The 42t is the smallest offset sprocket to fit the BBSHD 1000w. Barry.
