One by drivetrains are great for dropping weight and simplifying your drivetrain. They also seem to be great for manufacturers as the move to ditch the front derailleur has resulted in a number of companies springing up to provide parts to fill in the gaps. Companies like Wolf Tooth Components offer up parts to piece together your own one by drivetrain, but also to address another issue – wear and tear.

While the SRAM XX1 cassette is a marvel of product design and engineering, it seems that may riders are finding the aluminum 42t cog to be wearing prematurely compared to the other 10 cogs in steel. OneUp components just introduced their 42t replacement with an even larger 44t cog, but for those looking to keep the standard 42 tooth count, it looks like WTC will soon have your answer…

Shown in unplated prototype form on the brand’s Facebook page, the 42t replacement cogs will be shipping in about 2 weeks. Once available, consumers will have an option to extend the life of their pricey SRAM cassettes. Just like the OneUp cog, the new WTC 42t will snap into place as a direct replacement of the stock cog from SRAM. In typical WTC style the cogs will be available in “black, silver, red, and maybe blue” so you can add a bit of ano flair to your ride. Pricing TBD.
