Ibis made their long awaited announcement today of the new Mojo HDR, which is an updated or evolutionary version of their Mojo HD. The greatest addition this bike has over its predecessor, is that it allows convertibility via their limbo chips between a 26-inch based wheel with 160mm of rear travel (a.k.a. the HDR) and a 27.5-inch wheel with 130mm of travel (HDR 650b). This conversion capability was designed and built into the bike, so that the geometry and suspension function and work properly together, for a synergistic 26-inch and 27.5-inch package.
I Like It Both Ways
- 26″ and 27.5″ convertible
- Slightly stronger frame than HD
- ISGC mount compatible
- Fits larger variety of rear shocks – FOX Float X and XV
- .3 -.4 lbs lighter than HD
- Increased rear end clearance for 11-speed gearing
- Upgraded linkages
Compared to its HD brethren, the new frame, which was built with a new molding process, is lighter and stronger, yet retains the same stiffness. They shifted over the lower link to make room for the always coveted ISGC mount, and in addition they added more robust bearings to the link to take more abuse and increase their longevity. More room was added in the rear axle area for the wider 11-speed systems, so clearance issues with rubbing and fitting will not be a problem. Additional space was created around the rear shock, so that the larger piggyback designs, such as the FOX XV and Float X will fit.
In the 130mm HDR 650b mode/version you can run it with 130-140mm travel forks, while with the 160mm HDR, you can use 160-180mm lengths. The HDR can pretty much run any size 26-inch tire, but the HDR 650b is constrained to a maximum of most 2.35-inch tires, so we’ll have to see how the fatter Enduro type tires fit, and it appears that Ibis might make some slight modifications for that accommodation. The frame will fortunately allow you to run a HDR 650b in 160mm mode if you desire, but it will require the rear shock to have travel a limiter via a a 5mm spacer to keep the rear tire from hitting the seat tube. Later in the year Ibis will offer a separate rear triangle to retrofit the current HD for a special 650b configuration.
The Mojo HDR has a tapered headtube, threaded bottom bracket, 142mm rear TA, integrated direct mount front derailleur, comes in Reverse Vitamin P and Cobra Blue colors, and the frameset retails for $2699.99. The full bike kits are the SLX $4699, XT $5599, XTR $6999 and XX1 $6499. The HDR 650b has a 67.1º head angle with a 140mm fork and 67.6º with a 130mm, and chainstay length at 17.1″, bottom bracket height (w/ Neo Moto 2.3-inch tires) at 13.5″ with 140mm fork and 13.4″ with 130mm, and a of weight 6.2 lbs. The HDR has a 67.5º head angle with a 160mm fork and 66º with a 180mm, and bottom bracket height at 13.8″ (unknown BB on the 180mm).
