These chainrings have been designed to be used on a 1X system requiring a “Narrow/Wide” or as we call it TT Thick/Thin for the Middleburn RS7 Square Taper cranks. They are mounted directly onto your Middleburn RS7 cranks to give a standard 50mm chain line on your frame. Currently available in grey hard coat, but will soon also be available in black hard coat.
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.
