THE RS8 X-Type Uno is a versatile single ring chain set which can be used for single speed use or as a single ring on a geared bike.

The RS8 X-Type arms are forged 7075T6 alloy for increased strength. The Uno spider is the spider & ring is one piece; this saves a lot of weight & is maintenance free. The Uno is machined from a solid billet that starts out at 400g & ends up weighing just 83g. The Uno's are then finished in with Middleburn's HardCoat finish, this finish in tests lasts 4 times longer than standard anodising & the surface is 10 times more slippery.

The RS8 X-Type is designed to work with bottom brackets with a 24mm ID this is the size of Shimano & many other after market companies like Hope & Chris King.

Is this chainring 3/32? Would it work with a 9 speed chain?
29 Oct 2017
Hi, I have a surly long haul trucker and want to make it a 1x9, would this chainring work with a 9 speed chain?

This chainring will be a 3/32" ring but it will still be suitable for use with a 9spd chain and a 1x9 set up.

Unfortunately Middleburn don't produce a 42 or 44 tooth direct mount chainring. These are the only size options available from Middleburn.
