The RS8 X-TYPE arms are forged 7075T6 alloy for increased strength. The spider is machined from a solid billet that starts out at 400grams and ends up weighing just 65 grams. The rings are machined from 7075T6 aerospace plate and then finished in our Hardcoat finish. The Hardcoat finish in tests last 4 times longer than standard anodising and the surface is 10 times more slippery.
The total weight of the 170mm crankset is 716 grams.
Your chainset must fit onto your bottom bracket! There are currently four chainset/bottom bracket interfaces that you're likely to come across. If your bottom bracket is made by Shimano and it has splines, then you need an Octalink chainset. If your b/b is NOT made by Shimano and it has splines, it's almost certainly ISIS. There are a very few non-Shimano chainsets with Shimano Octalink interfaces so, to be sure, count the splines - ISIS has 9, Octalink has (surprise, surprise) 8. No matter which brand of b/b you have, if it has a square interface, it will require a traditional square taper chainset. If you have one of the new Hollowtech II systems, you will need to choose the exact chainset that matches your bottom bracket. Most MTB chainsets are now 9-speed compatible but these will work with an 8-speed system.
The name MIDDLEBURN is familiar to many hard-core riders in the mountain bike racing, trials and downhill disciplines, however some road riders, tourists and expedition riders may never have heard of them! Started some 20 years ago by Middleburn Engineering in Surrey, they have become known for British made high quality components that outlast the competition many times over. Middleburn are always expanding and updating their large range of chainwheels, spiders and cranks, all made in our their factories in the UK. In 2010 they launched, rather belatedly, their X-type thru-axle crankset. The ”Sweetorque spline” system means that they can offer many different options of spiders and rings to suit your bike, in single, double and triple set-ups. Between them they have wide experience of most cycle racing disciplines, component Design, CNC manufacturing, and indeed the cycle trade itself.
