Geometry and Sizing
Carbon, carbon, carbon, carbon, carbon Chameleon…
The tin lizard has ascended the evolutionary ladder and is now a fully-imagined carbon fiber creature. It’s Darwinism in action.
We took the fun-loving, shreddy spirit and adjustability of the beloved aluminum Chameleon and added a lighter, faster, more advanced version of the species. It’s a do-it-all hardtail that is as happy making the most of backyard booter (mis)adventures as it is fully-loaded with camp gear and a color-matched dangle mug. Two bottle cage mounts, including a triple-bolt cargo cage mount under the downtube mean you can escape from the crowds, too.
The Chameleon changes to suit its environment. Twenty-niner or 27-plus, geared or single-speed, this adaptable hardtail utilizes a suite of simple, swappable dropouts to convert it from aggro trail charger to single-speed racer to husky bikepacking mule, or anything in between.
Depending on setup and skill level, the Chameleon is capable on a wide range of terrain—aggressive trail riding to jump lines to all-around use. Going for maximum speed and rollability? Go 29er. Riding mostly loose terrain? Get some Plus tires that provide traction for days.
The most versatile bike in our range ticks even more boxes.

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.
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.
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.

Can I put a chainguide on the Chameleon C?
Yes! It comes with ISCG05 tabs, so it's easy to bolt a chainguide on.
What kind of brake mount does the Chameleon C use?
Both of the stock geared dropout options are Post Mount 160. The aftermarket Single Speed dropouts use an IS160 mount
What kind of headset does this bike use?
This bike uses integrated headset cups. The upper up is 41mm and the lower cup is 52mm. The SHIS name is IS 41/28.6 IS 52/40.
What size fork should I use?
Our recommended setup is 120mm for 29er and 130mm for 27+ bikes. This makes for similar angles and BB height between wheel sizes. Feel free to mix-and-match or put longer on there if you wish. We'd suggest a max travel of 140mm for optimal handling
What size tire can I fit?
The Chameleon C will accommodate up to 29x2.5 or 27.5x3.0. If you adjust the dropouts back a bit (lengthen chainstays) you can fit some 29x2.6 tires as well
Which dropouts do I need to run geared or singlespeed?
Wheel size-specific swappable dropouts maintain the same geometry while allowing the use of 27.5+ or 29er wheels in geared or singlespeed configurations. Geared options use 148mm 'Boost' spacing while the single speed options use 142 spacing to accommodate dedicated singlespeed hubs.
Why are there 3 bolts on the underside of the downtube?
This triple mount is used to mount 3-bolt "cargo cages" for carrying large waterbottles or various other items for bikepacking. You can also mount a traditional 2-bolt waterbottle cage.
