Mojo boss Chris Porter has stretched conventional limits of geometry and suspension tech, hoping to create the fastest descending bike that still climbs well. But has he created a masterpiece or a monster?

The Frame

Despite its outrageous length, the industrial-looking tubeset feels exceptionally stiff under power. The four-bar suspension has been tweaked to boost mid~stroke support and help it work well with air shocks.

The Kit

The Mojo—fettled Fox RC2 fork is simply the best single-crown we’ve ridden – stiff, supple and supportive. The sensitive and adjustable Float X2 rear shock more than matches it, especially with the clutch on the rear mech disabled to minimise friction. Fox’s DOSS seatpost was occasionally awkward and could do with a longer drop than 125mm - we lowered the saddle an inch to access the full descending potential. The rest is a well chosen, reliable mix of Hope, Shimano and Mavic kit.

The Ride

The active suspension» works busily underneath you. softening the terrain as you attack technical pitches with ease. We were surprised at the slippery sections we cleaned. and how easy the 32/40t lowest gear felt on brutal climbs. The steep 77-degree seat angle and long top tube put you in a comfy. efficient and we drift feel the need for a lockout.

Descending took some gelling used to. At first we found ourselves too rearward on steep descents causing the front end to wander. lt takes a conscious effort to weight the front wheel and attack the trail. We also found ourselves running wide on tight bends until we got used to the 62.8 degree head angle.

But on certain familiar stretches, the bike simply shone. On lnnerleithen's steep and nasty Jawbone trail, the GeoMetron felt calm and in control around the slippery, rocky corners. Not to mention fast. The slack head angle and long chainstays (445mm) and wheelbase (1,310mm) make slipping through rocks, roots and ruts incredibly manageable, while the supple suspension retains impeccable composure and traction.

Trail centre laps were effortless uphill, with cackle— inducing speed coming down. Pushing the long front end hard into berms required higher pressures in both the fork and front tyre, suggesting we were weighting the front harder than normal once we learned to trust the geometry. The GeoMetron occasionally feels lazy when stamping on the pedals or negotiating tight switchbacks, but otherwise it’s ruthlessly quick, confident and stable.
