The Mojo HD3 was an instant classic when launched in November of 2014. It was our most popular bike in 2015.
We announced a major update to the Mojo HD3 as of March of 2016. As of then, the Mojo HD3 became both Boost and Plus compatible.
Boost is a standard for axles and drivetrains that allows us to build a bike with a stiffer rear end and no weight penalty. It also allows us to increase clearance so we can run larger rubber on the bike. The HD3 now accommodates the incredible new 2.8" Plus tires from both Schwalbe and Maxxis. In the words of 'The Angry Singlespeeder" on MTBR, these tires have "Traction for Days". The level of grip with the new plus tires is just shy of Velcro.
The HD3 also features the latest and greatest refinement of the famed dw-link suspension. Geometry is fully modern: longer, lower and slacker, with 6” of plush rear wheel travel. We’ve built in versatile internal routing and updated the carbon fiber frame design, allowing us to put a water bottle on top of the downtube. We also achieve a drop in weight and pedaling performance on par with the Ripley, so the bike is very fast going up, and scary fast going down.

Sizing Guide (Rider Height)
Dropper Post Saddle Height Calculations
Do not try to insert your post deeper than these measurements. Forcing the post can result in a seat tube failure.
IMPORTANT: Before riding, check the saddle to tire clearance with the dropper post fully dropped and the air out of the shock with frame compressed to bottom out.
Saddle height used for dropper measurements:
49mm rails-to-top.
| Frame measurement | Small | Medium | Large | X-Large |
|---|---|---|---|---|
| Center-to-Top (mm) | 366 | 419 | 476 | 520 |
| Max Insertion (mm) | 155 | 185 | 230 | 275 |
