Description

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.

  • A 1x chainring from e*thirteen
  • 5mm thick aluminum is built for durability
  • The narrow/wide profile keeps the chain in place
  • Works with any 104mm BCD crank
  • Compatible with 9, 10, and 11-speed drivetrains
