Overview
Overview
When the trail (or the competition) calls for the direct drive efficiency that only a hardtail can offer, the Highball is the choice. It looks straightforward but that belies the high-tech features and design hidden within. This is a modern take on the simple machine that many still choose to put battery acid in their thighs and fire in their lungs in order to conquer something. Whether you’re chasing medals, personal demons, or just some riding buddies, this is a hardtail you’ll be happy to log long hours upon.

Sizing
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.
| Size | Height range | Reach |
|---|---|---|
| Small | 152cm 5'0" - 165cm 5'5" | 415mm |
| Medium | 165cm 5'5" - 177cm 5'10" | 440mm |
| Large | 177cm 5'10" - 185cm 6'1" | 460mm |
| X-Large | 185cm 6'1" - 198cm 6'6" | 490mm |
