MTB CHAINRINGS |
|
|
| |
 |
Middleburn chainrings are available in 4-Arm,CD, ATB and Shimano XTR960 fittings. All Middleburn Chainrings are machined from 7075T6 alloy and comply with industry standard fitments. This means they are compatible with almost any MTB chainset on the market today.
We offer two types of machining on our chainrings: Slickshift Chainrings which means they have ramps and pins to aid the change from one ring to another, and the Standard Chainrings which don't have ramps or pins.
We offer two different finishes for our chainrings. The first is anodising which comes in black, silver, red or blue and the second finish is Hardcoat, a Teflon impregnated ceramic coating which only comes in grey, see the chart below for availability.

Breakaway bolts are specially weakened derailleur pivot bolts that are designed to "break away" when a severe impact occurs. Much better to break a small bolt than to strip the threads out of your expensive frame, we think you'll agree! Lightweight too.
