Juliana Bicycles
MY20 Aquarius Green MATTE & MY20 Pink

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!

Tech Support

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.

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 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 does the rear axle flip chip do?

The axle flip chip changes the chainstay length by +/- 10mm. This provides a rider with choice about how the bike rides or fits. Shorter is more playful and lively, longer being more stable descending and more traction for climbing. It also means that taller riders can tailor the fit of the bike and create a balanced front-rear proportion.

And one more thing, on the Tallboy, flip the axle chip to long if you want to fit your bike with 29x2.6 tires.

To note is that the aluminum version of the Tallboy does not have an axle flip chip.

What is the largest chainring I can use on the Joplin?

With a proper boost chainring (52mm chainline), the Joplin will accept a 36t chainring or smaller.

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.

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 kind of headset does this bike use?

This bike uses integrated headset cups. The upper is 41mm and the lower is 52mm. The SHIS name is IS 41/28.6 IS 52/40.

What’s a flip chip?

A flip chip is a simple mechanism that we use to adjust geometry and suspension feel on our bikes. The lower-link flip chip sits in the shock mount in lower-link. This one adjusts the BB height up and down and the Lo setting makes the suspension more progressive (more bottom out resistance). The axle flip chip changes the chainstay length by +/- 10mm. This provides a rider with choice about how the bike rides or fits. Shorter is more playful and lively, longer being more stable descending and more traction for climbing. It also means that taller riders can tailor the fit of the bike and create a balanced front-rear proportion. 

And one more thing, on the Tallboy, flip the axle chip to long if you want to fit your bike with 29x2.6 tires. 
To note is that the aluminum version of the Tallboy does not have an axle flip chip.

Why the axle flip chip on the Joplin but not the Maverick?

The Joplin was designed to have a really short (430mm) chainstays so it was fun, lively and playful. However, we know that taller riders (or riders looking for more climbing and descending stability, regardless of their height) might enjoy the longer chainstays (440mm). However, the Maverick has a slightly longer chainstay (433mm) which is a good starting point for the travel and intention of that bike.

Note that the aluminum version of the Joplin does not have an axle flip chip.

Will I need to change my rotor size to change axle flip chip?

The Joplin come stock with 180mm rotors. This works in both short and long setting, you just need to change the brake caliper mounting bracket (supplied with the bike, including both short and long spare derailleur hangers).
