The Radavist

The number of silver 1x 110 BCD chainrings on the market is dismal. Particularly rings with smaller teeth count. IRD, or Interloc Racing Design, was formed in 1987 at the height of the MTB boom in America. Its latest product is a line of 104 or 110 BCD chainrings ($69.95). These rings are available in black or silver and in 34 through 38 tooth counts; 40 tooth count on the way in February for select rings.

These rings are 1x compatible without the use of a chain keep, but you might find that you’d need one if your rear derailleur doesn’t have a clutch. They’ll look great with your vintage MTB cranks, when paired with 1x chainring bolts.

You can order IRD products at your local bike shop through Merry Sales.

If you like riding at a spinny cadence, you probably rely on 28t chainrings for 1x drivetrains. Until today, one of the leading component manufacturers had yet to make that ring size in SRAM and Shimano direct mount. Wolf Tooth just announced its new 28t rings for SRAM T-Type and Shimano direct mount.

Note: these rings will not work with SRAM’s T-Type bash guard.

Check out the offerings at Wolf Tooth.

Earlier this year, Wolf Tooth announced aero chainrings for Shimano cranks and this week, the brand released its chainrings for use with SRAM gravel and road cranksets. Just like the Shimano rings, these SRAM rings were designed with performance in mind and feature a clean, integrated look that matches the profile of the crankarm or spider. New sizes include 46, 48, 50, and 52T depending on mount. They are compatible with most 12-speed chains and optimized for SRAM Eagle and Flattop chains, including Transmission. All Wolf Tooth chainrings are machined with 7075-T6 aluminum at Wolf Tooth in Minnesota, USA.

Aero chainrings date back to the 1980s and are still very much in vogue today, particularly in racing circles, but let’s be honest, they do look damn cool. Wolf Tooth just announced Aero Rings for Shimano GRX in a symmetric ($84.95) and asymmetric ($81.95) profile…

If you’re working on a vintage MTB conversion into a basket bike, commuter bike, or touring bike, and want to go with a 1x drivetrain, you’ll be shocked to find that there aren’t many options for vintage crank bolt center diameters. Stridsland took that as impetus to make some!

If you’re on the hunt for a 144 or 110 BCD chainring, look no further. Our buddy Aaron from AARN just released his stock for the year at the AARN webshop, including some very limited pieces like we’re showcasing here. These special edition rings are commemorating over a decade of making unique chainrings in the USA. Hop on over to his shop to check out the stock!

One ring to rule them all and by them, I mean all MTB groups from 11 through 12 speeds. This week, ROTOR announced new Universal Tooth Pattern chainrings for all mainstream MTB groups, from Shimano® 12s to SRAM® 11 or 12s. These rings come in round and oval and come in a variety of tooth counts.

-ROTOR Universal Tooth Design Chainrings are 100% compatible with
Shimano® 11s & 12s and SRAM® 11s & 12s MTB groupsets
-ROTOR Universal Tooth Design Chainrings are 100% compatible with

Wolf Tooth’s newest innovative product design is its CAMO system bashspider and chainrings. These bashspiders attach to the splined interface of MTB cranks and are paired with a CAMO chainring.

AARN, the engineering and manufacturing brand, best known for its chainrings, has just relaunched their web shop with more stock, including these limited-edition faded 144bcd rings. Head on over to AARN to see what’s still there as this stuff sells out fast!

The thing I love seeing is a modern road or ‘cross drivetrain with vintage-inspired or straight-up vintage silver cranks. If you’ve wanted to mix up your SRAM or Shimano built bike with something classier than the supplied cranks – which are designed to look good with carbon bikes, not steel frames, IMO – then check out this tidbit of information Jan from Rene Herse just announced.

In designing the Rene Herse chainrings, they anticipated the arrival of 12-speed, so the ramping design on these rings and the ring’s teeth width themselves have been engineered and now confirmed to work with 12-speed systems. I’m not talking “shift and it’ll eventually drop, ‘work'” I mean shift and it’ll smoothly engage.
