Chameleon Carbon 29 Mountain Bike Frame
The Santa Cruz Chameleon has defined the term versatility during its tenure as the brand's longest running model that's still in production. Long revered and beloved for its overbuilt stature and its ability to adapt to its owner's need, the Chameleon has been a favorite of aggressive riders who don't want or need a full-suspension bike. Throughout the years, the frame has transformed from 26-inch wheels to plus and 29-inch varieties, rim brakes to disc, quick-release to thru-axle, 3 chainrings to 1x, along with geometry tweaks making it capable of handling more technical trails. The one thing that remained constant is its frame material: aluminum. Well, a new day has dawned at Santa Cruz HQ, and the seventh generation Chameleon has received a carbon update. Leveraging Santa Cruz's mastery of carbon fiber construction, this lizard drops some weight and improves the ride quality. This particular frame, the Chameleon Carbon 29 Mountain Bike Frame, comes ready to rock with fast-rolling 29-inch wheels and is also compatible with 27.5+ wheels.
This fun-loving, do-it-all trail bike is on our short list of bikes we'd pick for long-distance bikepacking missions over rugged terrain. As we mentioned above, it comes out of the box ready for 29er wheels, however, if you want maximum grip and floatation over loose trails with plus-sized tires, its interchangeable dropouts allow the frame to happily accommodate. The dropouts also allow you to swap out the gears for single-speed use, should you desire a near-maintenance free drivetrain, live in an area without major elevation changes, or you just enjoy flogging yourself from time to time. Please note we carry the separate dropouts for both plus and 29-inch wheels as well as for singlespeed use where the spacing is 142mm while the geared version is Boost 148mm.
Geometry plays a key role in the Chameleon's versatility, with short chainstays, fairly long reach measurements per size, and a relaxed 67.3-degree head tube angle. It's recommended to pair with a 5 to 5.5-inch fork for taking the edge off of rough trails letting you tackle way more rugged terrain than you'd consider on a hardtail. What we love so much about the Carbon Chameleon is it can jump in a singlespeed race one weekend, hit the berms and jumps in the bike park after work, and load up with a week's worth of camping gear for a bikepacking vacation next. Eagle eyes will notice two bottle cage mounts, including a triple-bolt cargo cage mount under the downtube for carrying large water bottles or various other items for bikepacking.
The Carbon Chameleon uses Santa Cruz's Carbon C, its second-tier carbon, which boasts identical construction to the higher grade CC carbon but uses a different modulus that adds a tiny bit of weight while saving big on cash. The method remains the same, with unidirectional carbon plies wrapping between tubes, adding strength and long-term durability. An inner bladder applies outward pressure against the mold while the carbon cures to reduce resin pooling and virtually eliminates imperfections. This results in a frame that is so tough, Santa Cruz backs it with a lifetime frame warranty.
