Ibis Mojo HD Announcement

Lopes’s Influence

The HD has been in development for three years, before we started working with Brian Lopes. We had originally planned on a 68 degree head angle and had already done the CAD models that way. When we started working with Brian he pushed hard for 67 so we actually went back and redid the models. We’re happy we did.
Brian and his mechanic Joe also helped us refine the cable routing so that cables are well protected, run clean and friction free and also have compatibility with single and multiple chainring setups and adjustable seatposts.
Although people suspect we do, we haven’t been making special layups for Brian. He’s just been riding the most current rev of the latest proposed production layup and been giving us feedback. We’ve done several versions now and the frame he rode at Downhill World’s in 2009 isn’t as good as the one that the consumer will be able to buy (sorry Brian).
Brian and Joe were also pretty adamant about having the chain guide attach in some way other than just around the BB. They didn’t want the guide to be able to rotate when you hit the bash guard. Joe came up with tapping threads into the main pivot bolt to secure it and it worked really well. The head of the Ibis engineering department (the amazing and incredible Colin) refined the idea and designed a custom guide that we’ll be stocking for it. They’ll be made by MRP and one is pictured below (note the nifty bolt that secures it to the lower link-definitely click on this image for a bigger view).

Dropouts

The post-mount Magnesium left dropout is forged (as compared to the more common die cast). This gives much higher strength and more consistent material properties. It works out to be about the same strength as aluminum but at 2/3rds the weight.

Tires and Rotors

Depending on brand and depth of knobs, 2.35″-2.5″ tires will fit the Mojo HD.
You can fit up to a 200mm diameter rear rotor.

Cable Routing

Cable routing is provided for cable actuated adjustable seatposts.
An optional polycarbonate cable guard is available that bolts under the down tube.
Cable guides are all removable so you can have the cleanest possible look depending on your cable orientation and whether or not you’re running a front derailleur.

Polycarbonate Cable Guard

If you are an extremely aggressive rider, we’ve found that it’s possible to damage the brake line and derailleur housing that will be routed under the down tube. To prevent that from happening, we have available an optional polycarbonate cable guard that bolts on under the down tube. We don’t have a production version yet, so you have to look at the ProE render below.

About the author: Brian Mullin

Brian has been part of the Mtbr team since 2007, where he has become an integral member of the review and test staff, specializing in technical articles. He likes to push the limits in all the sports he obsesses in, whether it's mountain biking, whitewater kayaking, extreme skiing, or sport climbing. He takes those same strengths and a good dose of insanity to his reviewing and writing on mountain biking products, creating technical, in-depth and hyperbolic articles. Whenever he's not on the bike, he might be found watching MotoGP racing, otherwise look for him out on extremely technical singletrack.

    Awesome! Why show it with a super long stem and no adjustable seatpost? Seems this bike screams for a 50-60mm stem and a gravity dropper, etc.

    That might be the case, but there is still a lot of riders who are going to use it for a bike that can climb, I think the smallest stem they (Ibis) have on their part list is 70mm, but I am sure a lot of people will swap out for a smaller one.
