All Middleburn chainrings have been machined from aerospace grade 7075 T6 aluminium and are hard coat anodised for greater strength and resistance against wear and tear. Middleburn components are all designed and manufactured in the UK.
Please note – these UNO’s were designed to work with 11 speed Shimano and SRAM chains. They do work with 12 speed Eagle chains but NOT Shimano chains.
