Guidering 4 Bolt Chainring
Whether your current chainring is worn, bent, or has just seen better days or you're taking the plunge and setting up your mountain bike with a 1x drivetrain, the Guidering 4 Bolt Chainring from e*thirteen Components has you covered. The chainring features lightweight yet durable, 5-millimeter thick aluminum construction and the ubiquitous narrow/wide profiling for increased chain retention over bumpy trails.
e*thirteen spent many hours testing numerous tooth profiles to establish a shape that not only held the chain on better but also desired one that was long-wearing so the chain continues to stay in place even after some heavy duty use. It's fully compatible with 9, 10, and 11-speed drivetrains and it's highly recommended to pair with a clutch-style rear derailleur.
The Guidering 4 Bolt Chainring has a 104mm BCD and comes in the colors Black, Blue, and Red. The 30-tooth ring has a 47.5mm chainline and sizes 32 through 38-teeth have a flip-flop 49/50mm chainline.

Simple and Effective
- Familiarity: I've put it through the wringer
These narrow/wide E.Thirteen chainrings are a really solid replacement or upgrade option. Chain retention is about as good as anything else, and they seem to hold up longer than some of the alternatives. Plus, they're relatively affordable. An all around good choice.
