Rotor Bike Components Research Specialist Christie O’Hara steps into the Mtbr booth to showcase the Rex mountain bike line. Rotor’s entire mountain bike line has been redesigned for 2014 with new graphics and shapes, with the goal of lightening up the line and enhancing durability.

On deck are the Rex 1 and Rex 2 cranks as well as the New QX1 oval chainring.  The Rex 1 is a 30mm crank composed of a new 7055 alloy material and weighs in at 489g while the Rex 2 is a slightly more affordable version, still features a 30mm spindle, and is available as a 1x or 2x. The new QX1 narrow-wide oval chainring is available in 28-36t and can be replaced without removing the crank. For more information visit www.rotorbike.com.

    Do these oval front sprockets really offer any advantages? Thanks.

    I’ve been running Rotor Rings for 3 years now. They not only do they smooth out your pedaling. They are easier on your Knees and extend the range of your gearing.

    I’m going to order one today. Any recommendations on where to get them at? My LBS pretty much tried to sway me away from them so I’d prefer to buy them online at this point.
    Thanks.

    Turns out they do not have a product (yet) available for SRAM GXP cranks. :(

    Have been using these on my MTB for years. Got rid of my aching knees that way.
