Middleburn 4-ARM triple rings
have been designed for the best combination of performance and durabillity
8 / 9 / 10 speed compatible
Featuring our Hardcoat technology.
The middleburn rings have been CNC machined for maximum weight savings.
CNC machined from 7075T6, one of the strongest alloys available today for unsurpassed durability.
.
Rings in a range of anodised finishes and our Hardcoat finish.
The 4mm is the thickness of the chainring. Traditionally 4-ARM cranksets have used the same offset on the outer ring and this is the most commonly used, later Shimano cranks use 5mm.
Standard means the chainring has no ramps and pins to aid shifting.
