Ibis Mojo HD3 Build

by Brian Mullin on February 27, 2015

I recently got a brand new Mojo HD3 and had been slowly building it up during my downtime due to the snowy and wintery weather here in Colorado. I spec’ed the HD3 with their upscale X01 Werx kit, which comes with the X01 11-speed drivetrain and a Race Face Turbine Cinch crankset. Along with their regular parts selection, the Werx kit includes the Cane Creek DBinline shock, a Fox Float 36 fork and their uber wide 741 carbon wheelset.

Ibis Mojo HD Generation 3

The new Mojo HD3 is a 27.5-inch bike that has 150mm of rear travel and is compatible with 150mm and 160mm forks. The bike uses designs, expertis, and technologies from the older Mojo models and the newer Ripley, and combines those together to produce a long travel 27.5″ bike that has the best of both worlds. It’s able to climb like a goat and descend gnarly terrain with plushness and composure.

The dw-link HD3 has 150mm of rear travel and can use 150 or 160mm front forks. It has a tapered headtube, inside triangle water bottle mounts, a threaded bottom bracket, internal cable routing, a 12x142mm rear axle, is ISCG 05 compatible and has an integrated direct-mount front derailleur. The head angle is 67° with a 150mm fork and 66.6° with a 160mm, and chainstay length at 16.93″. The bottom bracket height (w/ 2.3″ tires) is 13.4″ with 150mm fork and 13.5″ with 160mm, and the frame weight is 5.9 lbs. It comes in four sizes (S, M, L, XL), and Matte Black, The Green Machine and 917 colors, and the frameset retails for $2900-2960, and kits range from $6000 to $9200.

Build Spec

I used most of the kit they sent me for the build but swapped out a few items that I like and those that I am current testing. The particular components are a set of the excellent Magura MT7 four-piston brakes (thanks, Magura USA) and the perfect fitting Syntace Megaforce 80mm long stem. I am testing the ergonomic SQlab 711 grips and SQlab 611 active saddle and an ultra sweet carbon riser handlebar from Level Nine.

Build Story

I had weighed every single component before the build began, just in case I needed a finely tuned breakdown at some point in time; plus it made my inner compulsive weight weenie happy. I used a temporary rigid seatpost so I could place the frame in my stand, and I began the build.

I installed the Cane Creek 40 headset and smashed the crown race down onto the Fox 36 fork, and cut the steering tube to my usual default length. I inserted the fork into the headtube and realized the steerer tube sat up higher than normal due to the zero stack headset bottom cup, so I’d need a few more spacers than usual to get everything hooked up. I added some spacers, the stem, and some more spacers, and I’ll leave it that way until I can fine tune the stack height for my riding preference.

I installed the Level Nine handlebars, the X01 shifter, the KS LEV dropper post remote and the SQlab grips.

Next, it was the drivetrain step, which meant installing the X01 rear derailleur and Race Face bottom bracket. I ran into a problem with the BB when I found out it needed a special Race Face tool for tightening. After hand tightening the BB, I ended up using channellock pliers wrapped with a soft cloth to finalize the fastening. It wasn’t a very proper method, but it worked (time to order the BSA30 Bottom Bracket tool). The new Race Face Cinch was easy to install after pushing the fat 30mm spindle through the BB from the non-drive side and highlights to their pre-load adjuster with a lock bolt for keeping everything tight.

I hadn’t used the new Ibis internal routing system, and it was slightly different since my frame didn’t include two newer ports that were specific to dropper post routing. I ended up getting the new Park Tools internal routing kit (IR-1) for assistance in this endeavor, and although it wasn’t very cheap, it became indispensable. After some experimentation and lots of scratching of my head, I ended up routing the seatpost down the right top port using housing the entire way leaving the excess housing dangling out the top of the seat tube. For the rear derailleur, I went down the top left port using the cable internally, coming back out the bottom right and used housing all the way to the derailleur itself. I routed the housing internally through the seat stay, so I had to drill out the routing ports to accept the thicker housing.

I wasn’t familiar with installing the SRAM 11-speed cassette to the XD driver body, but after some online searching, it made sense how it screws onto the hub. I screwed the brake rotors on the hubs and slapped the Maxxis tires on the 741 rims, and thankfully it didn’t take too much wrestling to get the bead installed. The tires inflated without issue using my small floor compressor. I then deflated them, added sealant and re-inflated.

I measured the chain to length, cut it and installed the PowerLock connector. I properly connected the cable to the derailleur and adjusted and tested the shifting, and it, fortunately, worked like a charm. I installed the Magura MT7’s in a moto setup (front on right, rear on left), and cut their hydraulic hoses to the proper length.

Lastly, I adjusted the cable and housing for the KS LEV dropper seatpost and clamped it down, and added and adjusted the tilt of the SQlab saddle. I added some pedals, and the bike was ready for a ride.

Build weight (w/ pedals): 28.74 lbs or 13.04 kg

Fitting Issues

I fit right between the medium and large frame sizes, and I have always preferred the smaller frames for better maneuverability in technical terrain. Instead of using the 50mm Thomson stem that came with the kit, I went with an 80mm size, utilizing my fave Syntace Megaforce stem (call me old school brained). While riding the bike around the block, it was instantly obvious that the 125mm KS LEV seatpost was too short. It was over an inch past the minimum insertion point, and it still needed to come up. I swapped out the 125mm for a 150mm, which gives me the proper seatpost height. Likely my height of 5’9″ and 32″ inseam exasperate the issue.

Findings/Problems Encountered

  • Race Face BB requires specialty tool  – BSA30 (need to buy one)
  • My early frame was missing the two newer internal routing ports for dropper posts (not an issue)
  • Park Tools internal routing kit (IR-1) – a worthwhile tool
  • KS LEV 125mm seatpost was too short – due to my height and small frame
  • Went with full housing from bottom downtube port to rear derailleur – drilled out seat stay routing ports to accept housing
  • Zero stack bottom headset cup makes for different stacking above headtube – just more fitting experimentation required
