Go Wilder

Saving weight means little without retaining an appropriate level of stiffness and responsiveness too. So we’ve taken all the acceleration and out-of-the-saddle sprint qualities of a carbon XC race rocket and fused them with a rear-end that still rails corners like a hardcore trail bike.

This unique XC-trail attitude is also reflected in the geometry. The head tube angle (67.1 degree) and reach (425mm) is a little steeper and shorter than a Joplin to meet the demands of aggressive climbing, yet the Wilder’s seat tube angle is a touch slacker and the chainstays a little longer than a Joplin too in order to retain that familiar Juliana confidence on descents. And talking of chainstays, each chainstay length is specific to the individual frame size; meaning riders of every height enjoy the same handling and performance no matter what.

Beyond the details, there are some bigger features that amplify this XC wild child’s abilities. Rapid rolling 29-inch wheels are paired with a 120mm fork to tame the feral lines and smooth the sketchiest of passing manoeuvres. There’s even room for two water bottles within the front triangle for bigger training and racing days.

Frame Sizing

If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.

Personal Preference

A larger size frame will be more stable, and will give you more room to move without upsetting the weight-balance of the bike. The larger size will put the front wheel further in front of you, which gives the feeling of security and conversely, it will require more significant body movements when you WANT to shift the weight-bias of the bike. Think hard about your riding style and how active/intuitive you want it to be vs stable and speedy. You'll need to work a bit harder to muscle the larger bike around.

Body Dimension

Not all bodies at a given height are the same. If you have longer legs and a shorter torso than the average person your height, that may push you towards the smaller of the recommended sizes. If you're all torso and arms, most likely you'll want to size up.
