For the past several years, e.thirteen’s guide rings have been many riders’ top choice for single ring applications and especially use with chainguides of all types. Their blend of light weight, low wear, and high strength help them complement the performance of any chainguide. Odd-sized guide rings are the next step for riders dialing in their drivetrains for race day. Not sure whether to run a 36t or 38t? Split the difference and run a 37t  guide ring for your race! Odd-sized guide rings let riders choose gearing that’s perfect for them, relieving the stress of race day and letting riders focus on more important things, like their race runs.

Odd-sized guide rings are available in 33t, 35t, 37t, and 39t options. All e.thirteen chain retention systems are compatible with the odd-sized guide rings.

Look out for more news coming soon from e.thirteen. The new RPM Orange Limited Colorways LG-1 chain retention devices are now shipping, and additional videos will be added to the e.thirteen website and YouTube page on a regular basis.
