You could call it the baby brother to the Mojo HD3 or the successor to the Mojo SL/SL-R. Either way, it’s a good thing.The Mojo 3 shares a lot of DNA with the HD3. Where the HD3 is a big and burly, the Mojo 3 is light and taut. The latest generation of the dw-link gives the bike its amazing climbing and descending abilities. Low, long and slack best describes the geometry, with the added bonus of extremely short chainstays. Notably, it’s not so slack that only a few World Cup Downhill pros can use it to its full capacity. The bike is nimble yet massively capable. The Mojo 3 also features a Boost swingarm, this makes for an overall stiffer rear end (wheel and frame). A highly evolved carbon layup makes the frame as stiff as an HD3 at only 5.45 lbs (with shock, size medium). Boost also allows you to fit 2.8” tires in 425mm chainstays and have the option of using a 2X front derailleur.
Let's start by focusing on the tire and wheel discussion for this bike, which is where the biggest areas of change are happening. The first thing many people will notice is the ability to run 27.5"+ tires on the Mojo 3. What’s not immediately evident is that you can also run standard 27.5” tires. In other words, you can choose either normal tires or 2.8"+ tires with the same frame and wheelset.
If a rider wants a fast/light setup or there is already plenty of traction in his/her area, a 2.2" - 2.4" tire will be great. Also, wide tires don’t work as well in the mud so if you’ve got sticky mud, take the plus tires off. You’ll have huge clearance for your thinner mud spikes, all with the same wheelset.
Need something a little burlier, but don't want to jump to the plus sized tires? Ibis worked with Maxxis to make a wide-rim specific tire, dubbed the Wide Trail, available so far with a few of Maxxis' most popular tires including the Minion DHF and Minion DHR II. This tire is specifically designed to be run on rims with a 30 - 35mm inner rim width. The side knobs are much more supportive and cornering confidence is increased immensely.
Ready to go for the plus sized tires? Through rider testing and feedback, Ibis has come to the conclusion that the Mojo 3 rides best with a 2.8"+ tire. The 3" - 3.2"+ tires tend to feel a bit too bouncy, and of course, weight is another factor. From the sounds of it, most of the testers came back with the opinion that 2.8"+ is the ideal width if you're going plus-sized. Big enough to get the benefits of greater air volume and traction, but not inherently bouncy or heavy. With a lightweight 2.8"+ tire, the bike’s capabilities jump a level while the weight/speed/rolling resistance drawbacks are minimal. Wide is good but too tall is bad. Tall is just an un-damped spring and those become a handful at speed. They do float along absorbing things at low speed but it all falls apart once you try to go fast over rough terrain. 2.8"+ tires need to be set up with relatively low pressures (13-16psi), at which point wide rims are mandatory. We recommend going with at least a 30mm inner rim width for the plus-sized tire range.
So that's that for the tire/wheel debate. On to the suspension. Here’s a little bit about Ibis' approach to shock tuning. As with many bikes, the goal is to create a supple beginning stroke, while offering enough support to absorb the harsh hits. Because the air spring is so well matched to the suspensions leverage ratio, the compression damping can be very light. This makes the suspension more effective and gives a smooth controlled feel. You also get more consistent suspension performance because the shock does not become under-damped as it heats up less under heavy riding. As expected, the Mojo 3 utilizes the tried-and-true dw-link suspension platform, offering excellent pedaling efficiency and a very supple feel overall.
