Geometry and Sizing
If ever there was a gravity riders’ XC bike, the Tallboy is it.
The 120mm Tallboy takes a leap further into what short-travel bikes really are capable of. With kick-ass lower-link VPP suspension, a streamlined design, the typical Santa Cruz refinement, and rather radical geometry, the Tallboy is back to being a genre bending folk hero.
Sure, 10mm more travel might only seem like one small step—but coupled with a lower link-driven VPP suspension design this is one giant leap for the Tallboy.
It’s the kind of bike that makes you sprint while going up, along, over, or down due to the maximum efficiency of the VPP design and responsive, lightweight chassis. But because it shares the same engineering principles as our longest travel bikes, the progressive lower link-mounted shock feels equally at home doing cross-country as it does in extreme-country. Paired with a 130mm fork the Tallboy becomes ever more appealing to riders who like to open it up.
And the geometry, that's a big part of what's going on...
Established theory suggests shorter travel bikes get ridden slower, therefore require steeper and more conservative geometries. In reality though, when was the last time you ever throttled back on a fun trail because you weren’t on a bigger bike? Caution to the wind and all that. So we’ve done the same here and mimicked our longer travel geometry to create a bike with a 65.5-degree head-angle, generous front center, and short offset fork. Something rarely seen on a bike of this ilk.
And the radical thinking doesn’t stop there. The Tallboy’s 436mm chainstays ensure that the bike stays nimble in every situation. Match that to a relatively low BB (335mm and 37.5mm drop) and you’ve got a combo that’s ready to haul into every pocket turn and launch out the other side.

If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.
A larger size frame will be more stable, and will give you more room to move without upsetting the weight-balance of the bike. The larger size will put the front wheel further in front of you, which gives the feeling of security and conversely, it will require more significant body movements when you WANT to shift the weight-bias of the bike. Think hard about your riding style and how active/intuitive you want it to be vs stable and speedy. You'll need to work a bit harder to muscle the larger bike around.
Not all bodies at a given height are the same. If you have longer legs and a shorter torso than the average person your height, that may push you towards the smaller of the recommended sizes. If you're all torso and arms, most likely you'll want to size up.

What is the maximum tire size?
29 x 2.5"
Can I fit a chainguide to my bike?
Yes, this bike is equipped with ISCG-05 tabs for easy chainguide mounting. Most chainguides on the market that are made for this standard should work.
I want to change my rear shock. Any limitations?
The Tallboy rear shock size is 190x45mm. The front hardware is 8x20, and the rear hardware is 8x30 (bearing compatible). The Tallboy is compatible with most air shocks, with the exception of the Fox Float X2 and Cane Creek shocks. Coil shocks are not compatible. For the best performance, we recommend sticking to the following: Fox Float DPS, Fox Float DPX2, Rockshox Deluxe or Rockshox Super Deluxe.
Should I ride my Tallboy in Hi or Lo setting?
You should definitely try both! We recommend starting with the Hi setting for the Tallboy but if you have steeper trails where pedal strikes are less of a concern, give Low a try.
The geometry chart shows two settings- how do I adjust that?
There's a "flip chip" on the link where the shock mounts. Just remove the lower shock bolt and flip the chips to the setting you desire.
What is the recommended fork?
Our geometry is based off of a 130mm fork with a 42 or 44mm offset. We wouldn't recommend less travel than that, as the BB will get a bit low.
