The Roubion is Juliana’s hard-charging trail bike for riders who never want to be out gunned, and there are some exciting updates for the 2022 model year.



What’s new on the 2022 Roubion 4?



New mixed wheel platform (29/27.5)

The new Roubion is sporting a MX wheel setup with a 29” front wheel and a 27.5” rear wheel on all sizes except XS, which is full 27.5”. The larger wheel up front adds that 29er trail crushing downhill capability while the 27.5” rear wheel keeps the bike nimble and playful. Anyone who’s tried the mullet style knows it’s a great combo that really feels like the best of both worlds, and the MX platform compliments the Roubion’s unruly nature perfectly.



Proportional geometry means a perfect fit for everyone

The Roubion 4 has size-specific chainstays and seat tube angles, meaning that every rider will get a custom-feeling ride that will ensure you get the most comfort, control, and confidence out of your bike.



More room in the cockpit for better confidence and control

The new Roubion is even more capable on the descents and confident in the air. With a 15mm longer reach, 20mm higher stack, and slacker 64.5° head tube angle, you’ll have more room to get airborne and better stability on the chunky steeps.
