Top quality UK-made crankset
I regret this item / version is out of stock
Middleburn cranks have been around since 1991 and have undergone a lot of refinement. The RO2 is the current incarnation designed for use with an external bottom bracket in a standard 68/73mm bottom bracket shell (you can also use them with various push-fit BBs but you need a different length axle). The Q factor is 153mm, pleasingly narrow by modern standards.

The cranks themselves are made from 7075 T6 alloy which is hot forged then CNC'd then hand polished. The resulting sculpted arms are super stiff, light and perhaps the most elegant on the market.

The interchangeable spider, manufactured by the same process, is a 94 BCD double with a 44mm chainline

The 9/10 speed chainrings have Middleburn's SlickShift coat and are ramped and pinned with a variable tooth profile to help shifting.
