MIDDLEBURN R01 Square Taper Crank

MIDDLEBURN, a British crank brand, offers sophisticated forged aluminum cranks that have been improved many times since 1991, and in recent years have evolved using modern technology such as 3D modeling. They guarantee to be the stiffest cranks on the market, yet lightweight.

The RO1 Square Taper Crank is made of "A7075", an aluminum alloy that is used by the aerospace industry.It is manufactured by forging and CNC machining.

The most interesting part of the crank is its finish. After machining, the entire crankshaft is hand-polished, and the logo is dug and inked at the very end. The logo is not printed on the crank, but is exposed as it is, which makes us fall in love with it.

The Alloy Cup Crank Bolts Set in MEDIUM is the perfect color to add a touch of color to the rugged cranks.
