Presenting some all new optic stimulation from e*thirteen. The e*thirteen chainring weighs about the same as a nats fart, so it's worth considering whatever the colour...


e*thirteen has a history of making sweet chainrings. In 2004 e*thirteen designed and released its first Guidering as a supplement to its already popular Single Ring Security chain retention systems. The 3mm thick 7075 chainring allowed for a perfect setup of all single ring chainguides on the market. It not only boasted a lifespan of more than an entire race season but was also the lightest on the market, weighing only 37.26 grams for the 36T size.

By 2007 e*thirteen had recognized the need for racers to more finely tune their drivetrains for specific race courses. So in early 2008 e*thirteen released its now popular odd sized Guiderings. By adding 33t, 35t, 37t and 39t options e*thirteen had once again pushed into an area where few had ventured in the past. The odd chainring sizes took a firm hold in both the downhill racing scene as well as in the single speed, fixie and cross country scenes.

Now in 2009 e*thirteen is doing something new and different purely for riders’ enjoyment. With the introduction of the Colorways Guidering program, riders and racers can bling out their favorite machines. e*thirteen is now offering all its Guidering sizes in a multitude of colors. The classic Silver Bullet and Jet Black will remain and the addition of Delta Gold, Red Rocket, PG Green, Grape Drink and Blue Steel will serve to round out the selection of the lightest, strongest, longest lasting AND NOW BEST LOOKING! chainrings on the market today.
