Custom engineered by Wolf Tooth to be durable, reliable, lightweight, and smooth. Weather sealing was a main focus with o-ring seals on the spindle and inner shell, a wiper connection seal between the bearing and the end cap, bearing race seals, and labyrinth end cap design. To prevent creaking, spindle bushings separate the bearing inner race and crank spindle to eliminate metal-on-metal contact. Custom chrome bearings are hardened for durability and reduced friction with ZNA corrosion-resistant coating, while ball diameter, width, and counts were custom selected for performance with each spindle diameter.
This 29mm bottom bracket will most commonly be used with SRAM cranks, as they use a DUB spindle.
Installs with standard 46mm 12 notch spline bottom bracket tool. (Same as DUB and RaceFace BBs)
Included Spindle Spacers: 2x 0.5mm, 2x 1mm, 3mm, 5mm, 7.5mm

El calor que emite no es suficiente
Style: Usb
El calor que emite no es suficiente para enfrentar temperaturas de menos 38 F°.
Salí en mi motocicleta y los probé y no sirvieron de nada. No lograron calentar mis manos. Obviamente usaba guantes y el nunca penetraron el material del guante. La temperatura era de 38 grados y llevaba protectores de puños para evitar el golpe del viento directamente.
