Highball 27.5 XC

The Highball is now available in 29” and 27.5”.  You pick. We tried to keep the handling characteristics the same between the two bikes, and let the wheel size’s traits shine through. One difference –the 27.5” version has a size small, while the 29er does not, and that the 29er has an XXL, while the 27.5” does not. On the 29er, we shortened the chainstays by almost a half-inch, and stretched out the front end of the bike by about the same. This allows you to run a more modern stem/bar combo and makes the bike a little quicker in the corners. A lot of folks want to talk about head tube angle when they talk about hardtails, but we rode a lot of different options, and decided the 70.5-degree angle we used on the first Highball was spot-on. It strikes the right balance of quick handling and stability, and won’t wander on you when you’re climbing.

Despite our commitment to carbon fiber engineering and manufacturing, we know the allure of a metal bike. Perfect welds, proper heft, and a certain tangible quality makes metal an attractive materail. It's also more amenable to the placement of bolts and other hardware than carbon is, which is why we offer a single-speed dropout kit in the alloy version of the Highball, but not the carbon. If you want to get your hammerhead on, we think this is the best way to do it. In addition, we reduced the seat post size to 27.2mm, which adds some compliance you’ll appreciate when you’re 80 miles in to a 100-mile race.

The Highball is unapologetically fast, surprisingly fun, and every bit a Santa Cruz mountain bike.

Size Guide






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 Derailleur Does The Highball Use?

The carbon fiber Highballs (both 27.5 and 29-inch versions) use a high direct-mount, bottom pull front derailleur. The aluminum version uses a 34.9mm clamp-on bottom swing/top pull front derailleur. 

What Kind of Headset Does the Highball 27.5 Use?

The Highball 27.5 uses an integrated headset with drop-in bearings and molded-in bearing races. The SHIS measurement is IS41 (upper) and IS52 (lower). 

What size bottom bracket shell does this bike use?

We use a standard 73mm threaded BB. Nearly any crank on the market (besides BB30 cranks) will fit.

What size rear hub do I need?

This bike uses a 142x12 through-axle rear hub, and includes a DT RWS axle.

What size seat collar do I need?

Bikes with a 27.2mm seatpost require a 31.8mm seat collar. 

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 chainring I can use on the HIghball?

If you want to use a single-chainring drivetrain on our new Highball, a maximum of a 36-tooth ring is your best bet. A 38-tooth ring will fit, but it's very tight. Any double-chainring drivetrain will work; we've checked a 42/30 combo, and it's no problem at all.
