Absolute Black GXP/BB30 DM CX Oval Ring The Absolute Black Direct-Mount Oval Ring is ready to rip it up with its beautifully machined, lightweight and stiff construction. Simply put, this is the best looking spiderless ring we've ever seen. Its special direct mount interface is compatible with SRAM GXP cranks that feature removable spiders. Simply remove your existing spider and bolt this ring on in its place. The spiderless setup is super clean and saves a great deal of weight over a normal spidered setup. Oval rings spin smoother and promote optimal power transfer, eliminating dead spots in the pedal stroke. The Spiderless GXP Oval Ring has Absolute Black's specialized narrow-wide tooth profile which retains the chain snugly, preventing dreaded chain droppage. Perfect for single ring or singlespeed use.
