The Mojo men write…
Over the last couple years, we’ve been working on a new 160mm travel big brother to the Mojo Carbon and Mojo SL (each with 140mm travel), we’re temporarily calling it the “Mojo HD”. And now we think it’s about time to tell you about it.
Introducing the Ibis Mojo HD
Before we tell you about what nitty gritty details we’re willing to divulge, we want to let you know that we’ve already been putting this bike through the paces, some of them rigorous.
Mojo “HD” Prototype Specifications
• Price and delivery date are both to be decided.
• 160mm of rear wheel travel.
• DW Link Suspension.
• 26″ Wheels.
• Target weight for the frame and shock: 6.2-6.5 lbs.
• 67 degree head angle with a 160mm fork.
• Chain stay length: 17.125″.
• Top tube lengths are the same as regular Mojos.
• 12 x 135mm Maxle rear axle.
• Post mount magnesium left dropout, carbon right dropout.
• Compatible with the new tapered steerer standard: 1 1/8th hidden upper, 1.5 traditional lower.
• Compatible with both Chris King InSet and Cane Creek Frustum headsets.
• If you want to run your current straight 1 1/8″ fork, we’ve got you covered too. We will have an adapter available, and you will be able to use a King headset top and bottom.
• 2.35″-2.5″ rear tire depending on brand and height of cornering knobs.
• Dual row angular contact bearings in the front of the lower link that have less play than standard sealed bearings. Preload adjustment is not necessary. Large 28mm x 15mm x 7mm radial bearings in the rear for stiffness and long wear.
• The leverage ratio, like the Mojo and Mojo SL is designed for air shocks. The Mojo HD comes with a 8.5″ x 2.5″ Fox RP23. A DHX air will work on all but the small size. A coil shock is not offered because the linkage rates weren’t designed for it. We lowered the top tube to get slightly better standover than the regular mojo while having a higher BB because of the longer travel (we managed to retain the DHX air compatibility in 3 of the 4 sizes).
• The Bottom Bracket height is 13.8″-14″ depending on tires.
• Chain guide development is well on its way, we’ll announce compatible brands soon. The frame will not have ISCG mounts so it will not be Hammerschmidt compatible.
• The HD runs full cable housing. Rear brake and rear deraileur run on the down tube, with hidden swingarm housing for the rear derailleur.
• Front derailleur (if you use one) and adjustible seatpost housing (if you use one) run along the top tube.
• And once again, just to make sure you got it, price and delivery date are both yet to be decided.
PSST…! A lonnng-term “second opinion” review of the regular Ibis Mojo by Ed “Bearded Lady” Oxley will be in the next issue of Singletrack Magazine – on sale early September.
