2025 was a big year for Wolf Tooth Components, as far as bottom brackets are concerned. First, they add a splash of color to their BSA and T47 internal BBs: Black, Raw Silver, Orange, and Ultraviolet Purple. They also added a completely new BB line, the T47 external BB, in the same color schemes.
Now, in true Wolf Tooth fashion, the brand is adding five new colors to its BSA and T47 internal lineup. This means nine (let’s check my math: 4+5=9, yes, good) BB colorways for you, bike component color-coordinating folks.
Wolf Tooth BSA and T47 BBs
Wolf Tooth’s T47 external, internal, and BSA BBs all fit the common spindle sizes: 24mm, 29mm, and 30mm. And, across the board, all BB from Wolf Tooth come in the Black, Raw Silver, Orange, and Ultraviolet Purple colorways.
However, only the T47 internal and BSA BBs have added more color options. Now, these BBs are also offered in Red, Blue, Gold, Olive, Green, and Espresso. These aren’t new colorways to Wolf Tooth and match its current offerings for components like dropper post levers.
The additional colors put the T47 internal and BSA BBs in Wolf Tooth’s Colorshop, where you can easily color coordinate between multiple components. We imagine they will also be coming to the T47 external BB and will update you when that happens.
BSA models have adjustable widths (different sleeves) to fit 68mm and 73mm shells (standard), as well as 83mm and 100mm shells. Wolf Tooth’s T47 internal BBs will fit 85.5mm to 92mm shells.
All BBs from Wolf Tooth are promised to be best-in-class regarding seals. They claim their five seals and o-rings balance low drag with high-performance in all weather conditions. BBs come with spindle o-rings, bearing/bushing gutter seals, inner/outer bearing race seals, shell o-rings, and labyrinth-style end caps. This keeps them spinning smoothly and unencumbered.
It also helps them not creak. Along with all the o-rings and seals, Wolf Tooth uses custom bushings to separate the inner race bearing and spindle. Doing so eliminates any contact between metal, which, along with water and debris leakage, results in the creaks and moans.
And then there are the different color options that look damn cool. I mean, come on, look at that Olive green! Am I someone who focuses on matching colors on my bike’s components? Not necessarily. But, when it is done well, does it look really good? Absolutely.
And Wolf Tooth seems to be leading the charge regarding color options! See all the different bottom brackets and other component color options at wolftoothcomponents.com.
