ABSOLUTE BLACK CASSETTE PARTS & ACCESSORIES
Great solution for Shimano cassette users who require that one more, extra sprocket on steep climbs. Very simple to install, it fits behind 11-36 cassettes, displacing one sprocket from the main cluster.
There are two ways to fit 40T sprocket to your drivetrain. You can remove the stock 17T sprocket and one spacer from your cassette, then put 40T on the freehub and mount everything else back (except 17T). OR, by removing 11T sprocket. Second option is a lot better in our opinion, but requires our special lockring to hold 13T sprocket (lockring is available in options).
If you don't know which option would be better for you, then just go for a ride and observe which of these two sprockets (11 & 17) you will miss less. Study shows, around 90% of mtb riders do not use 11T sprocket in terrain.
For running a 1X system, please use medium cage rear derailleur. When in use with 2x10, most recommended is long cage. Please note: weight limit is 100kg (220lbs). This product is not suitable for shifting under huge loads as it may lead to deformation of teeth.

Probably the best Singlespeed cogs(sprockets) on the market. Thanks to the unique tooth shape, narrow-wide profile and perfect roundness these sprockets will outlast any other aluminium counterpart. Each tooth is much wider and "square" compared to a commonly used shape. Addition of narrow/wide profile, taken from our award winning Sram spiderless chainring, provides additional teeth strength and offers greater chain retention if a tensioner or chain gets loose while riding. This is the first cog on the market offering such a feature.
Cog fits Shimano freehub bodies and offer a 7mm thick base to prevent the damage of alloy freehub under heavy loads. The teeth are central to the base, so they can be flipped around to double the life of the cog.
