Trainer Caps allow thru-axle bikes to be used with most wind, magnetic or fluid cycling trainers. Cold weather and short days are never far from a Minnesotan's mind so Wolf Tooth engineers created Trainer Caps to reduce barriers to winter workouts. Non-drive side axle caps are joined by drive-side plugs that can be installed or removed without tools to make the prospect of hopping on the trainer a little more bearable. - Compatibility: Wolf Tooth Rear Axles (not compatible with rear axles from other manufacturers) - Plug has O-ring retention – no tool required

Boostinators are hub specific conversions designed to take non-boost hubs and convert them to boost compatibility. Don't toss out that wheelset - Boostinate it.

The Wolf Tooth Rear Axle uses a captive steel washer under the head to reduce friction on the dropout face. This protects your expensive frame, transfers more of the tightening torque to clamping load for a stiffer interface and prevents the axle from sticking or galling when you want to remove it. - Made in Minnesota to aerospace standards

The Wolf Tooth axle uses a captive steel washer under the head to reduce friction on the fork leg. This protects your expensive fork, transfers more of the tightening torque to clamping load for a stiffer interface and prevents the axle from sticking or galling when you want to remove it. These are also a great replacement option for lost or damaged stock axles. Always apply a small amount of grease to the washer and threads when installing. - Designed and manufactured in Minneapolis, MN USA 7075 T6 Aluminum

Boostinator kits allow non-boost wheels to be mounted in Boost spacing frames and forks. While incremental, the benefits of the "Boost" 15x110mm front and 12x148mm rear axle standards are clear: better clearance for fatter tires & rims and reduced dish for stiffer, stronger wheels. The big bummer? Taking full advantage requires not only a new frame and fork, but new wheels as well. In response, we have developed the Boostinator. When paired with compatible 15x100mm or 12x142mm hubs, Boostinator kits allow existing wheels to be mounted in Boost-standard frames and forks. Disc and drivetrain positions are maintained and, thanks to a quick re-dish, spoke bracing angles are improved. Boostinator kits consist of a specially-designed axle end cap and, in the case of rear kits, a precision-machined rotor spacer with a set of six high-strength bolts. In keeping with Boost specifications, the disc and cassette are shifted outboard, allowing brakes and derailleurs to function as designed. Compatibility: - Front boostinators are only an endcap and do not require a rotor spacer. The wheel is re-dished. - Rear boostinators require both a re-dish and rotor spacer. - Rear Boostinator kits are not approved for rotors larger than 183mm. - Hubs spacing is 100mm front and 142 rear, and the Boostinators make them 110 and 148 respectively. - Compatible with 6-bolt FRONT wheels and SOME centerlock models. - Compatible with ONLY 6-bolt REAR wheels (there is no way to space centerlock rotors over 6mm). - NOT recommend (or safe) for non-symmetric lacing like the 2:1 lacing found on some of Industry Nine's wheels. *Note: You will need to re-dish your wheel after installing any Boosinator. Boostinator DR: - The Boostinator DR is compatible with DT-Swiss 12x142mm Star Ratchet (240- and 350-series) rear hubs with 6-bolt (IS) rotor mounts. - Centerlock hubs are not supported. - 180- and 190-series hubs are Centerlock only. - The Boostinator DR is also compatible with some complete wheels from DT Swiss, Roval (Specialized), Giant, Syncros (Scott), and others that use DT's Star Ratchet internals. - Remove the disc side end cap. Bearing size 6802 15x24. - Net weight: 18g Boostinator HR: - The Boostinator HR is compatible with 12x142mm Hope Pro 2 EVO and Pro 4 rear hubs. - Non-EVO Pro 2 hubs are not supported - Net weight: 18g Boostinator 9TR: - Compatible with 142x12 rear Industry Nine Torch hubs. - Not compatible with 2:1 lacing wheels from Industry Nine - Not compatible with Centerlock hubs Tech Specs: - Material: 6061 aluminum - Included: Rear kits come with appropriate-length Class 10.9 bolts, each roughly 40% stronger than more common Class 8.8 hardware.
