Geometry and Sizing
A little bit (cross) country. A little bit rock and roll.
The Joplin is a bit of an XC wild child, a light bike that’s heavy on capability with a “let’s go” attitude to any trail.
Let’s go fast. Let’s go far. Let’s go until your legs are ready to give up, and then go some more. Let’s make every second count. Let’s carve rides out of busy days and put those lines on the map on your done list.
The Joplin’s 29-inch wheels and lean frame float over washboard bumps with the same ease it devours jagged ledges. A geometry bred for long days in the saddle is blended with 130mm of travel in the front and 120mm in the rear, creating a capable climber that doesn’t flinch when roots get ragged and rocks start to roll. The lower link VPP suspension offers a responsive pedaling platform that’s ready to get up and go the moment you are. Whether you’re flossing rock gardens or making the rider in front of you your next hare, the Joplin is one rapid little trail fox that will take you farther than you thought you could and give you the confidence to go bigger than you thought you would.
With a size range that starts at XS, this bike brings big-wheel benefits to those of us in the fun-size category too. And yes, every size in the line fits a water bottle inside the main triangle because XS doesn’t mean “do things by half”. Tying up the package is a range of component builds that weave the line between fun and fast, creating a bike that’s ready to race the distance or just race the clouds home.
So, what are you waiting for? Let’s go!
|Head Tube Angle||65.7°||65.7°||65.7°|
|Seat Tube Length||370mm||380mm||405mm|
|Head Tube Length||90mm||100mm||110mm|
|Top Tube Length||539mm||567mm||596mm|
|Seat Tube Angle||76.8°||76.7°||76.6°|
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.

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 Joplin rear shock size is 190x45mm. The front hardware is 8x20, and the rear hardware is 8x30 (bearing compatible). The Joplin 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 Joplin in Hi or Lo setting?
You should definitely try both! We recommend starting with the Hi setting for the Joplin but if you have steeper trails where pedal strikes are less of a concern, give Low a try.
What are the main differences between the Juliana Joplin and Santa Cruz Tallboy?
The Joplin is spec'd with a shock that is tuned for lighter riders, a Juliana women’s saddle, and Juliana grips. It is offered in 6 kits.
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.
What is the maximum tire size?
29 x 2.6. You’ll need to flip the axle chip to the long setting to do this.
If you know the difference between a wrench and a spanner then we have a host of simple-to-follow guides for the basic service jobs.
We design our bikes to last, to be easy to work on and we make sure to provide the parts and information so you can make your bike last for many lifetimes.
