Middleburn cranks were first developed in 1991 and since then the cranks have undergone many refinements. This is the latest mountain bike crank which is designed to work with the external bottom brackets but also with push-fit type bottom brackets with the use of a different axle length. The design is the result of advanced 3D and stress modelling technique that ensures they are amongst the stiffest cranks on the market but also lightweight.
The cranks are hot forged from high quality 7075 T6 aluminium. They then go through a CNC machined process and are then hand polished followed by anodised before being re-machined with the Middleburn logo. All cranks go through the same procedure so whichever crank arm you choose will be to the best quality.
RS8 cranks are designed to work with the dedicated X Type spiders and X Type UNO’s to give the correct chain line. So whether you are running standard 50mm or Boost we can build your Middelburn cranks up to your exact requirements. If you purchase the cranks with a spider or direct mount UNO and wish to have it mounted on your cranks please put a note in your order to ensure that they are fitted. If you are unsure what you need please email us or call us for advice.
RS8’s are now available in sizes 165mm, 170mm and 175mm in either Silver or Black.
