THE RS8 X-Type Duo is a versatile two ring chain set. The crank set has a 26t inner ring & a 39t outer ring, this ratio is perfect for a 26” wheeled mountain bike.

The RS8 X-Type arms are forged 7075T6 alloy for increased strength. The spider is machined from a solid billet that starts out at 400g & ends up weighing just 65g. The rings are machined from 7075T6 aerospace plate & then finished in Middleburns Hardcoat finish. The Hardcoat finish in tests last 4 times longer than standard anodising & the surface is 10 times more slippery.

The total weight of the 170mm crankset is 716 grams.

Looking for new rings
middleburn X type spiders seem to come in different sizes, current ones (at least) seem to be labelled, you need to match the number of bolts and the PCD (pitch circle diameter) if your chainset looks like this thenit accepts 4-ARM XC 104/64BCD rings RT
