Middleburn RO2 X Type cranks come complete with a 24mm axle, plus axle nuts and fittings. RO2 road X-type cranks are for use in any external bottom bracket using 24mm bearings as per HollowTech2

The Middleburn RO2-X-175 cranks (including SP-RO2-X-94-X2 spider) weigh approximately 568g including all fittings. The Q factor is approximately 153mm

All our X Type cranks are fitted with a 24mm axle which works on any Hollow Tech 2 style Bottom Bracket.

Middleburn cranks were first developed in 1991 and since then the cranks have undergone many refinements. This is the latest road 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 light too.

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.

Image also shows some RO2's built up with the SP-RO2-X-94-X2 spider with dedicated 11 speed 46/30 chainrings and stainless steel bolt set.

PLEASE NOTE - DO NOT USE THE SHIMANO DURA-ACE BR9100 WITH THESE CRANKS. DUE TO THE DESIGN OF THE BB/SHIMANO CRANKS AND BEARINGS/SEALS FITTED THERE IS AN ISSUE WITH THE LOCK RING RUBBING AGAINST THE BB CUP. ALL OTHER BB'S ARE FINE.

If you purchase a spider or UNO with your cranks and would like it mounted onto them prior to shipping, please add a note in your order and we will make sure this is completed before you receive them.
