The third generation of Santa Cruz’s premium-priced benchmark trail racer gets a makeover and builds up either firm and fast as a 29er or fat and fun in 650b+ livery.

With its longer, slacker geometry the new Tallboy encourages a much more attacking attitude than most 100-110mm bikes

Santa Cruz Tallboy CC XX1 frame and equipment

While the first two iterations of the 29in wheeled, XC orientated Tallboy were very similar, with steep angled (70-degree head), short travel (100mm), 2.2kg frames, this third version is an altogether different beast. Travel (110mm) and frame weight (2.7kg) both go up, and the lower VPP suspension linkage also comes up in the frame to change the suspension kinematics.

The head angle slackens to 68 degrees, while the radically dropped top tube and seat tube make sizing up for a really long reach easy (L is 450mm, XL is 475mm). The Tallboy 3 is also one of the first short-travel full-suspension bikes to be both 29in and 650b+ wheel compatible, with a 148x12mm Boost rear axle and an adjustable suspension chip to compensate for the slightly different ride height (or not, depending on taste).

Santa Cruz has stuck with its tried and tested grease-injectable, adjustable-collet pivot bearings and super-reliable threaded bottom bracket (both very welcome) and it even has an old-school IS rear brake mount (not so welcome).

The Tallboy CC comes in four different build kits for 650b+ or 29in wheels, with additional suspension, bottom bracket and wheel upgrade options. They’re all trail, rather than cross-country, biased, with control-friendly chunky tyres and wide bars.

The XX1 build we tested in 29er format now gets SRAM’s latest 12-speed, 10-50t Eagle transmission and a RockShox Pike fork (the Fox 34 Performance Elite is an upgrade). UK bikes also boast Hope hubs and a KS LEV dropper post.

Santa Cruz Tallboy CC XX1 ride impression

The already low Tallboy is now longer and slacker, with added plus tyre compatibility
Russell Burton

With its longer, slacker geometry (and it was already low) the new Tallboy encourages a much more attacking attitude than most 100-110mm bikes and it has the chassis stiffness to back up bold moves. The pedal-interactive VPP suspension encourages a similarly hard-driving style, although overall weight dulls the Tallboy’s climbing edge slightly.

In 29er format the 120mm fork can get into trouble, though, and despite the normally faithful Maxxis Minion DHF tyre we regularly found ourselves losing the front end when things got too rowdy. Even with the compression damping fully open, the rear suspension tends to slap and clatter through trail trauma rather than carrying speed smoothly, and pedalling can choke the stroke and vice versa. Switch to plus-size wheels and tyres, though, and the unforgivingly bony suspension feel gets a pillowy effect with better small-bump absorption that immediately increases rough terrain momentum and front wheel traction, while reducing pedal choke (the proper 650b+ build gets a 130mm fork too).

Although the heavier wheels accelerate more slowly, time splits on back-to-back tests showed them to be significantly faster on technical trails, with a huge dose of swaggering, big grin confidence thrown in for good measure.


Santa Cruz Tallboy CC XX1 early verdict

Aggressively punchy as a 29er and flat-out, full-gas fun as a high-performance 650b+ bike.
