Ibis Mojo HD4 Announced

The Ibis Cycles Enduro Race Team*--currently the #1 team in the Enduro World Series standings--has been giving us feedback and recommendations for the last couple of years on what they want to see in a next-generation enduro bike. Our engineers, mechanics and designers have been working with the team to realize these goals, and we are pleased to announce the 4th generation of the Mojo HD, which we're dubbing the HD4.

• The HD4 features a completely redesigned geometry with a focus on stability and speed
• You can expect excellent big hit performance through increased progression in the shock tune
• After much experimentation and real-world testing, we've landed on a 64.9 degree head tube angle
• Reach has increased across the board (up by 4mm on small, to 34mm on XL)
• Compatibility with the longest droppers
• 30% stiffer upper link, 40% stiffer lower link
• Refined carbon layup yielding greater frame stiffness overall
• Features dw-link v5 kinematics, Dave’s most efficient system to date

• Available in Fireball Red, or Añejo Silver & Lime

"The new bike is inspiring to ride. I felt like I knew what it was going to do as soon as I hopped on it for the first run. When the trail points down hill and things get steeper, the bike is easy to move around, giving me that extra bit of confidence. After testing the bike for months, I am so happy we finally get to race it because it loves to go fast!"

Progessive Geometry

One of the design goals of the HD4 was to enhance the bike's handling capabilities over rough and steep terrain. The Mojo HD and Mojo 3 have had a lot of overlap and geometry similarities, with the new HD4 we are interested in separating the two bikes and growing the HD4's capabilities. We have been riding geometry testing mules for almost a year now, sampling different angles and lengths to determine the right feel for this bike. We've test ridden extensively in Santa Cruz, Downieville, Northstar, and in the high Sierras to get a feel for different terrains and traction conditions and the particular needs of each. 

In dialing in the geometry, we gave ourselves free reign to figure out what would work best. Instead of choosing a geometry by committee or based on other companies' bikes, we chose our geometry based on what worked best when we rode the steepest and gnarliest trails we could find. In our testing, we were able to see what each geometry dimension actually did to help the rider. For example, by trying a number of head angles back to back to back, with all other geometry dimensions held constant, we were able to pinpoint some desirable characteristics. The obvious one is that with proper trail measurement, the bike’s ability to steamroll through rough terrain is greatly enhanced. Less intuitive, but borne out by testing is that reducing the head angle will allow the bike to achieve higher lean angles before slipping out. This change also makes the bike more stable as the trail transitions to off-camber, meaning it’s less likely to slip out or get pushed down by the trail. On the Mojo HD4 we set the head angle at 64.9 degrees to maximize the stability in off-camber sections, increase our maximum lean angle and allow us to carry great speed through the chunder.

Ibis Mojo HD4 Geometry

Reach

We have seen many consumers buying bikes that were a size larger than we anticipated, indicating that we wanted to grow the reach of the Mojo HD4 by at least that much. We rode bikes with different reach numbers and were able to find a nice balance between being long enough without going too long. Compared to the Mojo HD3, size by size we increased reach by one whole frame size then added a little more. This longer reach combined with the slacker head angle greatly increases the wheelbase and gives a very stable ride for the roughest terrain.

Droppers

Like most people who ride aggressively on their trail bikes, we have really enjoyed riding with longer and longer dropper seatposts, especially as the terrain gets rougher and steeper. We recognized that having the seat completely out of the way made all the difference when things got really hairy. So we set out to give compatibility with the longest dropper posts available today, with enough room for adjustment to fit everyone. Compared to the HD3 we lowered the tops of the seat tubes roughly one size, so that a Large frame now measures 17.5" center to top. We also ensured the internal bore of the seat tube was deep enough. This allows riders to use the longest seatpost possible and still get their correct saddle height. On the Medium, Large, and X-Large sizes, almost everyone should be able to use 170mm dropper seaposts, while 150mm dropper seatposts should work for almost all Small size owners.

DW-Link

From the suspension standpoint, we absolutely love how the current Mojo HD3 pedals. We didn't want to mess with such a dialed suspension design so we left the kinematics the same for the Mojo HD4. What we did do, is engineer more progression into the shock leverage curve, allowing for more big-hit capability in very rough terrain. The travel went up a tiny bit, and it now has 153mm of rear travel. The bike is intended to fit a piggy-back rear air shock while still fitting a 22 oz water bottle in the frame. Coil shocks are not recommended, due to the clevis shock yoke extending the eye-to-eye too far to give a good bushing overlap ratio.

Travel

We think 6” of travel is right for most people's riding needs, we felt it struck the best balance for a climbable enduro style bike. With a longer travel bike comes the temptation to put 180mm forks on them, thus requiring heavier frame construction and moving the bike into a different category.

Variable leverage rates and shock tunes can make a 6” bike feel it’s got much more travel, or it can be the other way around. Since our dw-link bikes tend not to get stuck in the middle of their travel and have a very linear feel to them, the available travel feels consistent, predictable and more usable.

Another advantage of sitting a bit higher in its travel is that we can lower the bottom bracket height, making for a better handling bike, while not being prone to pedal strikes.

Linkage

With continued refinement, we've managed to eek 30% more stiffness out of the upper link as compared to the last iteration of the HD. This upper link is backward compatible to the HD3. The HD4's lower link's stiffness is increased by 40% compared to the links on the Mojo HD3 and is unique to the HD4.

SIX NEW RIMS AND WHEELSETS FROM IBIS

Two years ago, Ibis introduced the ultra-wide 41mm 741 and 941 wheels to a few raised eyebrows. Once people rode the wheels and experienced all the benefits, those raised eyebrows quickly became high fives. Elbow pad sales spiked due to the massive traction of the wheels, as lean angles to approached 90^°. OK, we made that part up but you get the idea.

4 In Carbon Fibre

• New Asymmetric Profile Carbon Fiber Rims
• Lower Profile Nets a 30% Increase in Impact Strength
• Less Material Saves 7.5% Weight
• Industry Nine Hubs Machined in USA
• Boost Front and Rear
• SRAM XD or Shimano Drivers
• 27.5" and 29" in 41mm and 35mm Outer Widths
• Wheels Built in USA
• Available May 1, 2016
• Wheelsets $1799

2 In Aluminum

• Asymmetric Profile 6066 Aluminum Rims
• New Super Durable Ibis Hubs
• Work Great with Plus Tires
• Boost Front and Rear
• SRAM XD or Shimano Drivers
• 27.5" and 29" in 38mm Outer and 35mm Inner Widths
• Available May 15, 2016
• Wheelsets $549

With the 742/942, we’ve retained the 41mm outer/35mm inner widths of our 741/941 rims, while increasing impact strength, reducing weight and maintaining all-important lateral stiffness.

The 735/935 feature 35mm outer and 29mm internal rim widths. The 735/935 are ideal for lighter trail bikes that see more XC time, and also great for riders looking to save as much weight as possible, while taking advantages of the features that wide rims bring you.

Our new carbon rim design features a lower cross section height for increased impact performance.  The lower 19.5mm section height makes the wheel better able to distribute the loads of localized impacts from rock strikes or hard landings.

Also, we are introducing a new hybrid carbon fiber layup, strategically combining layers of a new, high-toughness carbon/epoxy prepreg with our original carbon composite, increasing both ultimate strength and impact durability.  This, combined with the asymmetric rim design that features 5mm of offset (2.5mm on 735/935)  allows for higher spoke tensions that are nearly equal from one side of the wheel to the other. As a result of all this, the 742/942 nets a 30% increase in impact strength yet a 7.5% decrease in weight, compared to our previous rims.

Our carbon wheels now come with the excellent Industry Nine Torch hubs. The durable hubs are made in the USA in Industry Nine's Asheville machine shop, and feature a 60t ratchet with 6 out of phase pawls that results in a 3º engagement. They are equipped with Enduro bearings and come with either Shimano or SRAM XD drivers.

A wider rim delivers better sidewall support so in many cases you can run lower pressures in your rubber. Tires mounted on wider rims don’t burp as easily. Lower pressures, even a pound or two, do several beneficial things, including increasing the contact patch, which results in better traction. Running lower pressures on varied terrain actually reduces rolling resistance. Wider rims are stronger and stiffer. With increased traction comes increased braking control.

The 742/942/738/938 rims are ideal for the ultra low pressures (10-18 psi) that we like to run with 2.8 Plus tires (or 18-25psi for 2.25" - 2.5" tires). Running any of our 35mm internal width rims work incredibly well with the new 2.8 Plus rubber we've been riding from Schwalbe and Maxxis. The low system weight of the wheels with these rims and tires combined with the monstrous traction advantage have been a revelation for those who have ridden them.

We've also had great luck with the 3.0 tires on the rims, and our tire manufacturing friends have informed us that there are a lot of new Plus tires in the pipeline.

Wide Rim Benefits

• Dramatically increased traction
• Reduced rolling resistance
• Less tubeless ‘burping’
• Works well with Plus tires up to 3.0"
• Stiffer, stronger wheel
• lighter than most narrow aluminum rims
• Better braking control
• Improved flat protection
• More predictable feel
• You can run a lighter tire with similar durability
• Hookless bead rims are far stronger
• Easy to mount tubeless with just a floor pump

 About Ibis Wheels

Our new carbon wheels feature all the good points about our prior wheelsets, with a few bonus features. The asymmetric design with offset spoke holes allows us to build a wheel with identical spoke lengths on the drive and non-drive side. The spoke tension is evened out between the two sides this way, building a more durable wheel. We are using a new hybrid carbon layup as well, layering a new high-toughness carbon/epoxy prepreg with our original  carbon composite, which increases  both ultimate strength and impact durability. So they are lighter and they are stronger.

Our new carbon wheels come with the excellent Industry Nine Torch Hubs. The hubs are made in the USA in Industry Nine's Asheville machine shop, and feature a 60t ratchet with 6 out of phase pawls that results in a 3º engagement. They are equipped with Enduro bearings and come with either Shimano or SRAM XD drivers.

The 742/942/738/938 rims are ideal for the ultra low pressures (10-18 psi) that we like to run with 2.8 Plus tires. They also do wonderful things to the performance of a number of 2.25” - 2.5” tires that start with fairly rounded profiles. We run lower pressures in 2.25-2.5” tires with the wider rims as well, in the neighborhood of 18-25 psi depending on rider weight and riding conditions.

Kali Protectives Maya Helmet

Would you rather be hit by a 2x4 or a pillow? It’s a stupid question, but one that our current helmet standards don’t do enough to address. So we’ve built our Maya using a combination of cone shaped multi-density EPS, paired with a softer density foam around the head.

This combination of materials allows us to use our lowest foam density ever. While helmets typically utilize a foam density between 100-120 g per cubit liter, the density in our Maya is around 70 g. The benefit to using this softer foam is that it dissipates impacts faster and more efficiently.

In our pursuit of safety, we haven’t forgotten the other features that make helmets “Enduro” worthy. Which is why the Maya incorporates things like an integrated camera and light mount and a break resistant moto style visor. Other features include an antimicrobial liner with bug netting, our floating dual closure system for easy adjustments, and twelve vents with internal channeling for great ventilation.

Highlights:

• Weighs 350 g
• USA pricing is $100
• Available in size S/M and M/L
• Colors are Matte Black, EnduroBro Blue, and White/Black Duo
• Shipping today-ish (or whenever the California longshoremen strike is resolved)

Details:

• COMPOSITE FUSION PLUSTM Technology: incorporates cone shaped multi-density EPS foam for improved impact dissipation
• Uses softest density foam in the mountain bike segment, because softer is better
• Break resistant FlexyBillTM visor
• Integrated Camera/Light Mount. Works with GoProTM, ContourTM, and Light & MotionTM
• Antimicrobial liner with integrated bug netting5 Forward and 7 rearward facing vents, with deep internal channeling for ventilation
• Dual Closure Fit System which auto height adjusts

Ibis HDR Announced

The Mojo HDR continues in the very capable footsteps of our popular and highly regarded Mojo HD, taking its technology and versatility a few steps further. The "HDR" and the "HD" feature identical travel (160mm), the same suspension (the incomparable dw-link), and the same proven geometry.

The HDR adds even more diversity to its menu.

You're currently looking at the 26" wheel 160mm travel version of the bike. You can set it up with 160mm or 180mm front forks.

Over on this page, you can see the HDR 650b, featuring 27.5" wheels (that's why we called it the HDR 650b) and a ton of ways to set it up.

Maybe the best place to start would be the galleries tab, where we've got a few videos showing the bike in action along with some lovely big studio shots.

Features

• 160mm of rear wheel travel
• dw-link Suspension
• 2014 Fox Float CTD Adjust Factory Series with Kashima Coat, 8.5" x 2.5"
• 26" Wheels
• Weight for the frame and shock, size medium, matte finish: 6.2 lbs (~.1 lb difference between sizes and for painted frame)
• 67.5 degree head angle with a Fox Float 34 160mm fork
• Optional polycarbonate down tube cable guard
• Chain stay length: 17.125"
• 12 x 142mm Maxle rear axle
• 160mm post mount left dropout, carbon fiber
• Tapered Steerer
• Compatible with Chris King InSet 3 headsets.
• If you want to run your current straight 1 1/8" fork, adapters available
• 2.35"-2.55" 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
• Fox RC4 coil rear available as an option
• The Bottom Bracket height is 13.8" with 2.3" tires
• Front derailleur (if you use one) and adjustable seatpost housing (if you use one) run along the top tube
• Direct mount front derailleur

As we mentioned in the overview, the Mojo HDR is taking over where the very capable Mojo HD is leaving off. They share travel, geometry and suspension kinematics. There are some differences too.

The "HDR" is slightly lighter than the HD, around .3 -.4 lb (depending on size and color), yet is stronger and of equal stiffness. We've employed a new, more precise molding technique similar to that used in the Mojo SL-R to get the weight down.

By shifting around our linkage locations, we've managed to add ISCG 05 chainguide mounting functionality and dramatically increased the front derailleur compatibility across both the 2X and 3X spectrum. We've also increased clearance for the new 11 speed cogsets.

With some other tweaks to the frame, we've made the frame compatible with Fox's new lighter weight XV air cans on the CTD shocks. We've also added clearance for their new Float X piggy back shock.

But perhaps the biggest change of all is that we've made the HDR a fully functional 650b / 27.5" bike. Like its predecessor the HD whose travel you could set at 140 or 160, the HDR has two travel options. In 160mm mode you use 26" wheels and can have your way with just about any trail. And its climbing prowess in this mode is the reason why it's one of the most popular bikes on the enduro circuit. The standard front travel for the HDR is 160mm, though we have a 180mm offering which those people with larger dangly things between their legs prefer to ride.

With a new set of "Limbo Chips" and a shorter shock (the same on shock on the Mojo SL-R), the bike can be set to 130mm travel mode, and with a set of 650b / 27.5" wheels and a fork, you've got yourself a bona fide 'tweener', not a 26", not a 29". That's called the HDR 650b.

Want more travel in 650b mode? Here's what you do: Set the frame up in the 160 travel mode, and add a 5mm travel reducing spacer in the shock. Deflate the shock to check that your tire won't hit the seat tube at bottom out (tire sizes vary a lot). You'll get 150mm of travel in this mode. 

So the HDR has an exceptionally versatile chassis. One that can be beat pretty hard in all day lift riding (put that 180 fork and a coil shock on those days), or run it in shorter travel mode with 650b wheels for a low and slack medium duty trail bike that will probably still net you a few uphill and downhill KOMs (if you're into that sort of thing).
