Middleburn chainrings are made in the UK from 7075 aerospace specification aluminium plate. Middleburn say "This is the strongest available material, and also the most expensive. They are produced by milling and turning using the best available CNC techniques, software, and in-house tooling strategies evolved by ourselves over 20 years. As engineers we feel we are creating works of art. Middleburn chainrings are available in 4-Arm, CD, ATB, Road, Shimano XTR960 and XTR970 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".
