If you need a specific chainring for your crankset, there’s a good chance Wolf Tooth Components has it. If not, just wait a few months – they’re probably already working on it! Adding to their collection of direct mount chainrings are new options in both round and their PowerTrac Elliptical for SRAM 8-Bolt cranksets.

For the most part, SRAM has used a 3-Bolt design for their direct mount chainrings. But for power meter cranks and new DUB road cranks, they use another 8-Bolt standard. Wolf Tooth Components already offered two round rings for the 8-Bolt pattern, but now they’ve drastically expanded the options in both round and oval.

All of the 8-Bolt rings are sold in Drop-Stop B Tooth Profiles which is meant for most chains including the SRAM Flattop AXS chains. The only chains they are not compatible with are Shimano 12 speed Hyperglide+ chains. The rings are available with a standard offset for a 45mm chainline.

Prices for both round and PowerTrac Elliptica start at $84.95 and they’re available now.

The SRAM 8 bolt interface is the biggest pita…. 8 little T-20 bolts that better not be tightened more than the 4N-m spec.

SRAM designers must have fastener fetish.
