For the cyclist looking to get a bit more torque from their 10 speed drivetrain the Absolute Black 40 tooth cassette cog is just the ticket. Allowing riders to increase the range of a traditional Shimano mountain cassette this cog makes nailing that extra steep climb a cinch. Meticulously machined from 7075 Txxx aluminum, then anodised for maximum durability, this conversion ring offers riders a simple and elegant option for easier gearing. Never miss that crucial shift again thanks to every tooth being profiled for smooth crisp changes. This ring will make climbing a breeze whatever your terrain. Recommended rider weight limit of 220lbs. Compatible with SLX, XT and XTR cassettes.
Installation: There are two options for mounting this 40 tooth cog.
The first requires removing the 17 tooth cog and spacer from the cassette and then reinstalling normally.
The second option is to remove the 11 tooth cog and install the cassette with Absolute Black's 13 tooth cassette lockring.
Absolute Black recommends the second mounting option as the 11 tooth cog is seldom used on trails, but choose the option that is best for you.
When running a 1X system a medium or long cage derailleur is recommended. If running a 2X system only a long cage derailleur should be used.
