The Guidering M is e*thirteen's take on 1x drivetrain living. Constructed from hardwearing EXA aluminum, the M Profile Direct Mount Guidering is optimized for all chainguide systems in order to prevent chain jamming, while the Dual width "M" (narrow/wide) tooth engages the chain securely even at extreme angles to prevent chain drops on even the most unforgiving trails. While the Guidering works wonders in preventing dropped chains, for the most secure chain retention, E*thirteen recommends using a clutch style rear derailleur and an XCX chain guide, as over time chain wear/stretch, ring wear, and rear derailleur clutch friction deterioration can reduce the retention capacity of the Guidering M.
With its direct mount interface, this version of the Guidering M is only compatible with E*thirteen TRS cranks.
Primary Uses: Any bike with a 1x (single chainring) set up
These chainrings are excellent. the guys at the HIVE are always inventing/upgrading bits and pieces to make our rides better. These are almost as easy to swap as the RF Cinch system if you buy the appropriate tool....about $15. If you are keeping the cranks and having several CR to swap out depending on the course, the tool is a worthwhile investment. LBO isn't happy about you bringing in the crank and new Guidering and asking to mount it. I have three Guiderings, and change them when needed. easy. jr
