Stigmata CX

The Stigmata is a cyclocross bike deserving of the Santa Cruz name. 

We do things a bit backwards here at Santa Cruz. While most companies first introduced carbon fiber on their road bikes, we made mountain bikes from it to prove its strength and versatility as a material. Then we made a downhill bike. And now we’ve made a carbon Stigmata—a 'cross, gravel, just ride your damn bike bike.

We started the development of the new Stigmata a couple years ago, because we missed the old Stigmata, and felt that there was a lot we could do with carbon that we were unable to do with aluminum. At the same time, hydraulic disc brakes for road bikes were becoming a reality, meaning that we wouldn’t have to put up with ancient braking technology to get our drop bar on.

The new Stigmata is versatile. It’ll fit 41mm-wide tires with room for mud, but handles nicely with skinny road tires for base miles. It’s also home to our first PressFit 30 bottom bracket. We didn’t make this decision lightly, but not only is PF30 capable of accommodating all road bike cranks, it allowed us to make the bike lighter while maintaining the strength and durability you expect from Santa Cruz.

Size Guide



Can I Use Electronic Shifting on the Stigmata?

You bet. We tried to make the bike as "future-proof" as possible, and we ship it with inserts for one-by drivetrains, mechanical drivetrains, and electronic drivetrains.

How Wide of a Tire Can I Fit in the Stigmata?

At least 41mm, and we've been running WTB's Nano 40 with great success. There's some extra room for mud (or more tire), but 40mm is the largest we've tried.

What is the torque spec for the seat collar?

We don't provide a torque spec for the seatpost, because it really depends on what seatpost you are using. Some seatposts are slippery, and require more torque to stay put, and others are very thin- and can be crushed by overzealous tightening. Some are both slippery and thin... Make sure you use the Carbon Assembly Compound included with your frame, and use some common sense.

You will not damage your frame by overtightening the seat collar, assuming you have a 27.2mm seatpost in there.

What Kind of Headset Does The Stigmata Use?

The Stigmata uses an integrated headset with drop-in bearings. The fork has a crown race molded in, and the headtube has a bearing race molded in at the top, as well. The SHIS measurement is IS41 (upper) and IS52 (lower).

What Kind of Thru-Axles Does The Stigmata Use?

The Stigmata uses Maxle Lite thru-axles in both the front and rear: 142x12mm rear and 15x100mm front.

What Kind of Wheels Can I Use on the Stigmata?

While the 142x12mm rear spacing would suggest that you could use any old mountain wheel in the frame, that's not quite the case. If you're intending to run a 10-speed drivetrain, any mountain wheel will indeed work. However, if you want to run an 11-speed road drivetrain, you'll have to ensure that the freehub body is designed for road drivetrains. Road freehub bodies are slightly longer than mountain freehub bodies, which means that if a mountain wheel is used in the Stigmata with an 11-speed drivetrain, the chain will be dangerously close to the frame (and likely rub the frame), and the cassette lockring could potentially unscrew itself. The exception are wheels that use SRAM's XD Driver, although SRAM currently does not make a cassette for the XD Driver that will work with a road drivetrain (max cog size on a CX1 derailleur is 36 teeth, current XD cassettes use 42-tooth large cogs).

Front wheels are vastly more straightforward; any wheel with a hub using the 15x100mm axle standard will work.

What size seatpost do I need?

This bike uses a 27.2mm seatpost. Always ensure it is inserted a minimum of 4" (100mm)

What's the Largest Rotor the Stigmata Will Take?

The Stigmata uses 160mm rotors, front and rear. You can use a 140mm rotor in the rear, but we felt the 160 offered better performance.

Why PressFit 30?

The Stigmata is our first and only bike using a non-threaded bottom bracket, and it's not a decision we made lightly or hastily. The reason for the PressFit 30 is two-fold: one, we wanted to make sure that the Stigmata would be compatible with road cranksets, where 30mm spindles are much more common, and two, PressFit 30 requires less frame material, which results in a lighter bike. While the early days of PressFit bottom brackets were plagued by manufacturing inconsistencies, the dust has settled, and it's a very versatile and commonly-used standard.
