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.

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.

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.

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.

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.

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.

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

29 x 2.6. You’ll need to flip the axle chip to the long setting to do this.

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.

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.

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.

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.

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).
