E. Thirteen has recently released their guide rings in odd sizes. Now I’ll be honest here, I’m not a down hiller or use any sort of guide system. Why am I so excited? For single speed use. I’ve seen their rings in person and they are light yet very strong to deal with down hill demands.

e.thirteen™ continues to push the envelope of product development with the release of more groundbreaking products for 2008. Beyond continued chain device development, e.thirteen is making additional contributions to the drive train with the release of odd-sized guide rings.

For the past several years, e.thirteen’s guide rings have been many riders’ top choice for single ring applications and especially use with chain guides of all types. Their blend of light weight, low wear, and high strength help them complement the performance of any chain guide. Odd-sized guide rings are the next step for riders dialing in their drivet rains 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.
