MIDDLEBURN BIKE CHAINRING RS8 & RS7 X-TYPE UNO TT THICK/THIN SPIDER

Middleburn RS8 and RS7 X-Type Uno direct mount Uno spider and chainring with the thick/thin type teeth for use in a 1x system. The RS8 & RS7 X-Type cranks run on a 24mm axle that is compatible with the Shimano hollow tech 2 system.

The TT Uno’s are machined from 7075 T6 aerospace aluminium and then a hard coat anodising treatment is applied for maximum strength and wear protection.

The chain line is a standard mountain bike of 50mm. We will be introducing some boost sizes soon so please keep checking the website and social media for updates.

These UNO’s are suitable for both types of X Type crank we produce and give the same chainline. So you can use these on the RS8 X Type and RS7 X Type but NOT the Square Taper RS7 SQ’s. If in doubt please contact us.
