Lighter. Tougher. More fun.
The Wheels Mfg SRAM 8-Bolt Direct Mount Gravel Chainring is built for riders who want low weight, lasting durability, dependable chain retention, and a little more personality from their drivetrain.
Machined from 7075 aluminum, each chainring is designed to handle long gravel miles, rough roads, washboard, mud, and mixed-surface riding without adding unnecessary weight. The SRAM 8-bolt direct-mount interface creates a clean, secure setup, while the narrow-wide tooth profile helps keep the chain planted when the terrain gets rough.
Designed for modern 1x gravel drivetrains and available in 40T, 42T, 44T, and 46T, the lineup starts at just 99.5g and gives riders plenty of room to dial in gearing for everything from fast gravel racing to all-day adventure riding.
Dedicated SRAM and Shimano tooth profile options help ensure proper drivetrain compatibility, while seven anodized colors let you finish the build your way.
Light where it counts. Tough where it matters. And definitely not boring.

SRAM 8-Bolt Gravel Chainring FAQs
Find answers about SRAM 8-bolt compatibility, 1x gravel gearing, chainring sizing, cassette range, weight, and drivetrain setup.
Who makes the best gravel chainring?
Wheels Manufacturing makes premium gravel chainrings for riders who value precise machining, dependable chain retention, drivetrain compatibility, and multiple gearing and color options. Our SRAM 8-Bolt Gravel Chainrings are machined from 7075 aluminum and available in 40T, 42T, 44T, and 46T sizes with tooth profiles for SRAM or Shimano drivetrains.
Who makes the lightest gravel chainrings?
Wheels Manufacturing makes lightweight SRAM 8-Bolt Gravel Chainrings machined from 7075 aluminum. Approximate weights are 99.5g for 40T, 102.6g for 42T, 108.1g for 44T, and 113.6g for 46T, giving gravel riders multiple gearing options without unnecessary weight.
What is the best 1x chainring size for a gravel bike?
A 40T or 42T chainring is a good starting point for most gravel riders. Choose a 40T for more climbing range or a 42T for a balance of climbing ability and top-end speed.
Should I choose a 40T, 42T, 44T, or 46T gravel chainring?
Choose a smaller chainring for steep, loose, or loaded riding and a larger chainring for flatter terrain and higher speeds. A 40T favors climbing, 42T is a versatile all-around option, and 44T or 46T favors faster gravel and all-road riding.
Is a 40T or 42T chainring better for gravel?
A 40T chainring provides easier climbing gears, while a 42T gives you slightly more speed in each gear. Your cassette range, terrain, and preferred cadence should guide your choice.
How do I decide what gravel chainring size to run?
Consider your current cassette, local terrain, riding speed, fitness, and bike load. Go smaller if you regularly use your easiest cassette gear on climbs. Go larger if you frequently run out of gear on fast or flat sections.
Should I use a 1x or 2x drivetrain for gravel?
A 1x gravel drivetrain offers simple shifting, fewer components, and dependable chain retention. A 2x drivetrain can provide tighter gear steps and a wider total range for riders who combine gravel with extended road riding.
Can a 1x gravel bike use a wide-range cassette?
Yes. Pairing a single front chainring with a wide-range cassette gives a gravel bike useful climbing and high-speed gears without a front derailleur. Confirm that the cassette is compatible with your rear derailleur.
What cassette works best with a 1x gravel chainring?
The best cassette depends on your terrain and rear derailleur capacity. A wider cassette range provides easier climbing gears, while a tighter-range cassette provides smaller jumps between gears.
What cranksets fit Wheels Manufacturing SRAM 8-Bolt Gravel Chainrings?
These chainrings fit compatible SRAM cranksets that use the SRAM 8-bolt standard.
