Mojo

The word Mojo refers to a magic spell or charm, and more broadly - a magical power. Since its introduction in 1994, the Mojo has delivered a wicked combination of fun and all-mountain prowess.

GEOMETRY

The Mojo V4 fea­tures a 76.6-degree, get-you-up-that-hill seat tube angle, our short­est chain­stays, and a spa­cious reach with a 65.4-degree head­tube angle. This enchant­i­ng com­bi­na­tion rolls on 27.5” wheels, to deliv­er that hov­er­bike feel with on-trail confidence.

DW-LINK

Since 2005, we’ve part­nered with sus­pen­sion guru Dave Wea­gle on the dw-link sus­pen­sion plat­form. It pro­vides an unpar­al­leled com­bi­na­tion of climb­ing effi­cien­cy and down­hill per­for­mance, which has been proven repeat­ed­ly at the high­est lev­els of racing.

TRACTION TUNE

Our cus­­tom-tuned sus­pen­sion fea­tures extra light high-speed com­pres­sion and rebound damp­ing to deliv­er unpar­al­leled trac­tion. When paired with our dw-link sus­pen­sion plat­form, Trac­tion Tune allows the Mojo to track like a big bike with­out com­pro­mis­ing crisp ped­al­ing per­for­mance.

PICK YOUR SIZE

All four sizes have low stan­dover heights and short­ened seat tubes for long drop­per posts. Now you can choose your frame based on reach — rid­ers 5-feet tall eas­i­ly fit on a small and still enjoy a 125mm drop­per, while most medi­um and up rid­ers can enjoy a 185mm. All sizes fit a water bot­tle, and those look­ing to go pack­less can run our after­mar­ket Pork Chop bag.

FORK OFFSET

Reduced-off­set forks give the front wheel greater sta­bil­i­ty at speed and an addi­tion­al sense of steadi­ness at slow speeds too. The Mojo is designed to excel in tech­ni­cal, demand­ing ter­rain, and the 37mm-off­set gives that extra bit of con­fi­dence and con­trol in the most chal­leng­ing situations.

TIRE CLEARANCE

The Mojo has clear­ance for 27.5”x2.6” tires. You can run over­built, chunky tires; you can run light, big vol­ume fast tires, but what­ev­er you run, know that you’re not lim­it­ed by width.

BUSHINGS

Tired of hit­ting pur­chase” on anoth­er set of bear­ings each sea­son? So were we. That’s why we use bush­ings where they make sense, and bear­ings where they don’t. The IGUS bush­ings in our low­er link are lighter and stiffer than bear­ings, and vir­tu­al­ly main­te­nance free. We believe so strong­ly in them, we back them with a free life­time replacement.

LIGHTWEIGHT PREMIUM CARBON FOR EVERYONE

All our bikes are built from the high­est grade mate­ri­als and opti­mized for the best strength, weight, stiff­ness, and ride per­for­mance — no mat­ter how much you spend. The Mojo weighs a svelte 5.9 lbs with an inline shock and com­plete builds start at 26.7 lbs.

INTERNAL CABLE ROUTING

Bikes that look pret­ty on the out­side, should look pret­ty on the inside. We use car­bon fiber tubes mold­ed with­in each frame. Push the cable in, watch it pop out, a beau­ti­ful moment indeed.

PROTECT YOUR INVESTMENT

A poly­car­bon­ate down­tube pro­tec­tor deflects debris, while mold­ed rub­ber swing arm pro­tec­tors keep things qui­et and clean. And our sim­ple-yet-ele­gant link­age pro­tec­tors stop mud and rocks thrown by the tire, keep­ing your beau­ti­ful bike beautiful.

Mojo Specific FAQs

All our manuals are available here.

The Mojo can accommodate up to a 27.5” x 2.6” tire.

The max chainring for a Mojo is a 34t.

Yes, the max size oval chainring we recommend is a 30T. Not all oval chainrings are the same, so we recommend double checking clearance before installation.

You can find torque specs for the Mojo in the tab on the right.

No, the Fox 36 is longer than the 34, forks, so a 150mm travel 36 will put too much stress on the frame. A 150mm travel Pike will be ok.

The Mojo uses 160mm post mount rear brake mounts.

To run a 180mm rotor, you'll use the following Shimano part number: SM-MA-F180P / P2
To run a 203mm rotor, you'll use the following Shimano part number: SM-MA-F203P / P
