absoluteBLACK Oval 76 BCD Chainrings greatly improve traction and climbing abilities. They are designed for Rotor REX cranksets with their original 1x spider. Lighter and stiffer than original chainrings, these provide a super-smooth pedaling sensation. The specially designed narrow-wide tooth profile keeps the chain snug, allowing you to leave your chain keeper in the garage. They are crafted from CNC machined 7075 aluminum and feature an anodized finish for exceptional durability. Ovality has been optimized for each chainring size, ranging from 10.2-14.4%, with timing of 110.5-116.3° after TDC (top dead center). - Only compatible with Rotor Rex cranks - Oval shape reduces stress on knees, helps to keep your legs fresh, and does not feel any different while riding - The unique, patent-pending narrow-wide tooth profile keeps the chain in place - Teeth have been 3D-machined for ultimate mud shedding and quieter operation - Provides excellent weight-to-strength ratio

absoluteBLACK Round Direct Mount 1x Chainrings for CINCH allow for flawless boost drivetrain setup. They are designed for Race Face cranks that utilize the CINCH system. Direct mount chainrings provide significant weight savings over a standard spider and chainring combination. They are crafted from CNC machined 7075 aluminum and feature an anodized finish for exceptional durability. - The unique, patent-pending narrow-wide tooth profile keeps the chain in place - Teeth have been 3D-machined for ultimate mud shedding and quieter operation - Provides excellent weight-to-strength ratio - 3mm offset is designed for bikes with Boost spacing and fat bikes (when reversed)

The absoluteBLACK Oval Bash Guide is designed specifically for oval chainrings, keeping your chain secure at every single crank position.

More power, better traction, less shifting. Wolf Tooth oval chainrings use our proprietary PowerTrac design that has all the benefits of oval but without the funky, uneven pedal stroke. Ride one once and you’ll wonder why you waited so long to try oval. Think of an oval chainring as two chainrings in one. A major benefit of the oval is how the shape of the chainring alters your gearing in two important phases of your pedal stroke by harnessing your body’s natural biomechanics. Here’s how it works. The area of the chainring with the larger diameter engages with the chain at the optimal point on the downstroke, which is what’s known as the Power Zone. If you were to look at a clock, the Power Zone would be between 1-5 and 7-11. Conversely, the Recovery Zone – back to the clock face, between 11-1 and 5-7 – is the weakest part of the pedal stroke, when the oval maximizes your efficiency. A 34T oval chainring behaves like a 36T chainring when you want power while behaving like a 32T chainring when you’re climbing. We’ve also engineered our oval chainrings to provide smoother, more efficient pedal rotation. This equates to better traction because of steadier torque on the rear wheel. With a Wolf Tooth oval chainring, you can harness more of your strength in the Power Zone, while having easier pedaling in the Recovery Zone. The direct mount chainrings for SRAM cranksets replace your existing spider and chainring with one clean-looking, lightweight, and stiff piece of machined billet. They are available in 3 different offsets: 6mm offset for 49mm chainline, 3mm offset for 52mm chainline, and 0mm offset for 55mm chainline and SRAM Transmission optimization. They are available in various tooth profiles to suit your drivetrain, including Drop-Stop B, which is optimized for SRAM T-Type Transmission and compatible with many other chains.

The Wolf Tooth Quick Release Seatpost Clamp allows for easy saddle height adjustments. An ergonomic lever on the side of the clamp opens and closes the clamp, which is held together by a bolt with a bronze bushing that lets the rider set the torque. It is friendly with carbon, steel, alloy, and titanium frames. - Bronze bushing for smooth lever action - Low-profile ergonomic lever - Stainless steel bolt with spherical washer - CNC machined 6061-T6 aluminum

Wolf Tooth ReMote Light Action has a longer lever arm than the standard ReMote and is optimal for dropper posts with a harder pull or for riders that just prefer a really light actuation feel. It reduces the force to actuate a dropper by nearly a third of the standard ReMote. Based on rider feedback and tailored to work with some posts' stiffer internal springs, the ReMote Light Action is also the choice of those with thumb injuries or reduced hand strength. - Upfront cable fixing - Large diameter ball bearing - Cable-kind clamp - Low-profile, light action - Integrated cable adjust - Breakaway axle pivot - High-traction lever - Broad compatibility

The Wolf Tooth ReMote Pro is the most adjustable and refined dropper lever. It can be moved laterally along the handlebar and rotated around the handlebar as can be done with all dropper levers, while also allowing for 48 deg of rotation to set the lever starting point, independent of cable tension – no other dropper lever allows for this to be adjusted. ReMote Pro also has a cable pulley with a cam (oval) shape that provides more leverage at the beginning of the lever throw; this is when dropper posts need more force to open the fluid reservoir valve that allows the post to move. And just like other Wolf Tooth dropper levers, ReMote Pro features a large sealed custom bearing and is machined at Wolf Tooth in Minnesota, USA. - Machined surface of paddle provides extra grip - 6061 T6 aluminum construction with Delrin axle - Large sealed cartridge bearing is shielded from the elements - Stainless steel bolts for unprecedented adjustability - Cable clamp won’t pinch or bend cable - Integrated barrel adjuster is the only plastic component - Compatible with all cable-actuated dropper posts - Various clamp options to integrate with brakes from popular manufacturers
