MSW Dimension Chainring

This chainring is designed for 130mm BCD cranksets and is optimized for 3/32" chains. As long as your crankset matches that bolt circle diameter and you are using a standard single-speed chain, it should be a direct fit.

Shift ramps and pins are designed to help a chain move between gears on a multi-speed drivetrain. Since this is a dedicated single-speed ring, those features are unnecessary and can actually increase the risk of the chain dropping; a smooth, flat profile ensures the chain stays securely seated.

While it is specifically optimized for 3/32" chains, it can technically accommodate a 1/8" chain. However, you may experience a slightly looser fit, which can lead to increased noise or wear compared to using the intended 3/32" chain width.

Yes, the design is versatile enough to mount to standard 130mm BCD cranksets regardless of whether they utilize a 4-bolt or 5-bolt configuration.

The aluminum used here is chosen for its balance of low weight and durability. It is perfectly suited for the rigors of daily commuting and urban riding, offering a long service life provided your drivetrain is kept clean and properly lubricated.
