The Cloud Perform CH-CM4-E chain guide embodies the lightweight and efficient solution to secure your single chainring drivetrain on technical Enduro and All Mountain terrain. With only 59 grams on the scale, this Ø34.9mm clamp-mounted guide ensures optimal chain retention without weighing down your machine, while offering reliable protection against unexpected derailments in the most demanding sections.

Technical highlights

• Extended compatibility: works perfectly with 1x9, 1x10, 1x11 and 1x12 speed drivetrains, covering a wide range of modern single chainring configurations.
• Universal Ø34.9mm clamp mount: easily attaches to the front derailleur location, without requiring ISCG mount or frame modifications.
• Optimized hybrid construction: upper guide in reinforced plastic to absorb vibrations and reduce noise, clamp in aluminum ensuring rigidity and reliable retention.
• Height adjustment: precisely adjust the guide position relative to your chainring for maximum efficiency and quiet operation.
• Featherweight 59 g: ideal compromise between protection and lightness, without noticeable penalty on bike dynamics.

Use and preferred terrain

Designed for Enduro and All Mountain riding, the CH-CM4-E excels on mixed trails alternating technical climbs and demanding descents. It keeps the chain in place even during rough sections (roots, rocks, harsh compressions) where derailment risks are highest. Its reinforced plastic upper guide captures the chain smoothly while limiting unwanted noise, while the aluminum clamp guarantees solid and durable attachment to the seat tube or former front derailleur location.

Installation and frame compatibility

Installation is performed via simple Ø34.9mm clamp, replicating the mounting logic of a traditional front derailleur. This universal format allows adaptation on the majority of modern MTB frames equipped or formerly equipped with a front derailleur. The guide height is adjustable to accommodate different chainring diameters and optimize positioning relative to the chainline. However, be sure to respect the recommended torque to avoid any damage to the frame tube, and regularly check the tightness after the first rides.
