Wickwerks has added a larger 42/28 chainring combo in the 120/80 BCD for SRAM and Race Face 2×10 drivetrains. This larger setup complements their 40/26 originals, but upgrades the big rings bolt holes to threaded cutouts that don’t require a bolt and nut.
The new rings give riders a refreshingly larger option to the increasingly diminutive gearing on new bikes, and the direct-thread mounting design is pure bonus. Wickwerks’ chainrings are CNC machined from 7075-T6 aluminum then hard anodized with military grade ano treatment. Engineer Eldon Goates says this process doesn’t give them control over the color (hence no purple, blue or red ano), but its far more durable than cosmetic anodization. He says under a microscope it has a hollow wormy surface, which they apply a Teflon finish. Goates admits the Teflon won’t last more than a couple hundred miles, but it improves performance while it lasts, so why not?
Detail pics and actual weights after the break…
Retail is $132.50 and includes the bolts. Actual weights are 78g for the big ring and 31g for the little. Total = 109g.
No more nuts, just thread into the chainring and head out for a ride. This makes it quicker and easier to both install and check/fix on the trail in case things come loose, as happens from time to time. We have a set of Wickwerks rings on review now.
