Description

Go Anywhere

Sure it's a tall order, but the Santa Cruz Chameleon frame may be the basis for the world's most versatile bicycle. Ready for 29 inch or 27.5 Plus wheels, and built to handle everything from bikepacking, to hardcore trail riding, to mid-week cross country races, consider this the starting point for a machine that will cover more bases than any other bikes in your quiver. 

The Chameleon has become one of Santa Cruz’s longest running and most beloved models in a large part because of its no-nonsense functionality. Originally conceived as a heavy-duty trail bike that could handle jumping, slalom, and a plethora of build options, the Chameleon has adapted to modern trends, but retains 100% of its trademark utility. 

This version of the Chameleon is compatible with both 29-inch and 27.5+ wheels. The change requires different dropouts, which are available separately from Santa Cruz, should you want to get a second wheelset. The dropouts also provide adjustable chainstay length, which can be used both to fine tune handling, and to provide chain tension should you opt for a singlespeed build in the future. 

As befits a truly utilitarian steed, the Chamelon is built from aluminum, which is both impervious to rust and highly resistant to impact damage. This choice of materials also results in a fairly modest asking price, which makes the Chameleon both an excellent introductory mountain bike, and a tempting addition to any well-equipped stable. 

Geometry plays a key role in the Chamelon’s versatility, with short chainstays, fairly long reach measurements per size, and a relaxed 67.5-degree head tube angle. The 5-inch fork takes the edge off of rough trails without resulting in the dramatic geometry shifts that can occur on hardtails with longer travel forks. And while it’s certainly a jack of all trades, the Chameleon shines in a number of different roles, and practically begs to be reconfigured over time to meet your changing needs.
  • Versatile hardtail for trail riding, bikepacking, and adventure
  • 67.5-degree head tube angle for confidence in technical terrain
  • Swapping dropouts adapts the frame to 27.5+ or 29in wheels
  • Aluminum frame is built to go the distance
  • Easily convertible to singlespeed with replaceable dropouts

Versatile and Fun

    I built this bike up with parts I had accumulated through various other bike builds as a spare. It's quickly becoming my go to rig because it's just so much fun. Updated geometry and the versatility to change wheel sizes, fork travel, and number of gears makes this hardtail a clear winner. I set mine up as a 29er, with a 130mm fork and the bike rides well basically everywhere.



    I've owned a number of Santa Cruz frames, and the quality here is nothing less than what I would expect from SC. i expect to have this bike for years and miles to come (which is saying a lot for me, as I usually swap bikes out yearly). And if I get bored with it, I can just convert it to an SS, or maybe even a 27.5 plus bike.

    Versatile and Fun

    The hardtail I've been looking for.

    • Familiarity: I've used it several times

    Over the past few years, I have really gotten in to the geometry changes on modern trail bikes and, while my full suspension rigs had kept up with the changes, my hardtail was still XC oriented. Every time I rode it, it felt very nervous and sketchy to me. I don't ride hardtails much any more but I always have one around for when the mood strikes me.



    The Chameleon feels just like my 150mm trail bike as far as fit, geometry and handling go. Now I can go from a long travel rig to a hardtail and don't have to get used to anything other than the fact that I have 0mm of rear suspension travel.



    The ride is very nice, the Chameleon feels fast and flowy on smooth trails and carves corners exceptionally well. the long front end and short rear end make the bike fun and snappy, yet stable and predictable. you can lift the front end and manual over stuff easily but the front wheels stays planted when you want it to. High speed stability is superb. The medium was a perfect fit for me at 5'9" and the reach feels good with a 50mm stem.



    I've only got about 50 miles on mine so far but have had it on everything from gravel roads to chunky, technical singletrack and it handles it all well. Climbing is good; it doesn't feel too slack and there's no wheel flop. Descending is confidence inspiring without any of the nervousness that a steep XC oriented hardtail will give you. If you're a trail rider who's used to the newer geometry, you'll feel right at home on the Chameleon. It also jumps great and feels super stable in the air.



    Mine is built up with a 120mm Fox Float and (mostly) Shimano XT8000 1x11 drivetrain. I've got a relatively light wheelset on the bike at the moment as well as, carbon cranks, carbon bars, and a stealth dropper. With this build it weighs in at right around 27lbs. The internal dropper routing is easy to use and the build was fairly straightforward. Just a couple notes: you will need an I.S. brake adapter for the rear brake (I went with a 180mm rotor on the rear) and you will also want to make sure your chainring/ crank setup has the 3mm offset for the 51mm boost chainline.



    This is my first Santa Cruz and I'm very impressed with the quality, fit and finish on the frame. I'm definitely digging it and will be looking at Santa Cruz again for my next bike.
