We spent a good bit of time debating around the office as to whether the Ibis Hakka MX Disc Ultegra Di2 R8070 Complete Bike holds its own in the category of gravel grinder or cyclocross speedster. Some of us looked at the beefy tubes and tire clearance and saw nothing but off-road adventures, while others argue that its road-inspired geometry would best be suited for race days at the CX course or graded gravel. But then something magical happened — we came to a consensus — with two wheelsets the Hakka MX can defy our hasty categorizations, and so we bring you this iteration not just with one Reynolds wheelset, but two — one with a wagon-wheel 700c for catapulting you to the finish line of gravel races left and right, and a second with plush 650b wheels to soak up abusive trails and load up for weekend trips in the desert, exploring unseen canyons coated in petroglyphs.

If you've been passionate about the cyclocross scene for some time, chances are you've had a crush on the Hakkalugi at one time or another. While the Hakka MX's roots don't sprout up too from the Hakkalugi tree, it rebels against its forefather with geometry tweaks and updated standards that we're pretty sure you'll find infatuating. Straying away from cyclocross and delving further into offroad exploration, the Hakka MX embraces stiffness with 142 x 12mm thru-axles, as opposed to the 135mm dropouts of the past. It further stiffens things up with the new T47 bottom bracket, which combines the stiff shell of a PF30 with the tried-and-tested reliability of a threaded bottom bracket for a squeak-free hold while you ride. A wider range of crank diameter spindles can be used on the T47 bottom bracket without sacrificing bearing diameter and larger spindles forced in a standard diameter threaded shell. The bigger shell also yields larger contact areas between the tubes offering greater drivetrain rigidity. . Rear, removable, fender mounts at the bottom of the seatstays and the rear of the bottom bracket shell will come in handy during a muddy gravel race, winter training, or commuting.

Engineers at Ibis mountain bikes have been building exclusively from carbon fiber for several years now and their expertise with the material means they know how to build a stiff, light, durable, and responsive frame. A tapered headtube provides the perfect foundation of unyielding stiffness needed for excellent tracking, hard braking, and out of the saddle climbing. The included ENVE fork contributes to the stiffness while working in tandem with the frame to absorb the jolts from washboard descents and all the rocks and roots found off the beaten path. Internal routing ports set up the Hakka MX for a clean finish, while a new internal Di2 battery mount enables us to put together this particular build with a smooth-shifting Ultegra R8070 Di2 electronic groupset. This newest iteration of Ultegra Di2 sets you up with many Dura-Ace-esque refinements, like slimmer profile and reworked shift levers positioned for better access when you're on the hoods.

But it would seem that we're beating around the bush a bit, and while the frame updates pique our interest, the ball is driven home by the two Reynold ATR carbon wheelsets that come ready to roll on this build. These two wheelsets enable you to transform your single bike into two different machines — a race-ready cyclocross steed, equally at home at your weeknight road ride as jumping hurdles in a mud pit — and a plush ride that begs to dive down the gravel roads less traveled, rekindling a nostalgic sense of adventure that many of us lost after childhood. Both crafted from Reynolds' meticulously laid carbon, the wheelsets offer you two different personalities. We opt to pair the smaller 650b wheels with an extra-plush 47mm tire to offer you a bit of pneumatic suspension on rougher terrain, while pairing the 700c hoops with a slimmer 28mm tire for road prowess — though the bike can accommodate up to a 40mm 700c tire, should you be wanting to add a little more supple traction to your wagon wheels.

Breaking the law!

  • Familiarity: I've used it several times

"No Open Flames" the sign at the trailhead read. I knew the moment the tires of the Ibis Hakka MX hit the dirt beyond that sign, I would be breaking the law. This bike is nothing short of hot fire!
I had already taken this bike out on a mostly pavement heavy ride with just a dash of singletrack and had fallen head over heals in love with this bad mamba-jamba. When I got out on some proper dirt is when this bike really came to life for me.
I can count on my fingers the amount of times that practically no honey moon phase was needed for me to fall hard for a bike. The Hakka MX had my heart and mind almost immediately sans a quick saddle and stem height adjustment.
The Hakka MX did everything I asked of it and surprised me on more than one occasion. I felt like I had a tailwind no matter where I pointed the bike on pavement or dirt. The 650b WTB Byway Plus tires scrambled up some pretty weird blown out fire roads and two tracks and left little to he desired on the pave.
The bike was planted down some pretty steep blown out grades and though I still had to pick my lines the bike's handling characteristics gave me confidence in spades to tackle the tasks at hand.
It should be against the law for a bike to be this versatile and this good!
I can't say enough good things about this bike. The future of road bikes has arrived and for anyone looking for the Swiss Army knife of bikes, the Ibis Hakka MX has landed.

Breaking the law!

You had me at MX.

  • Familiarity: I've used it several times

I am a mountain biker. that is my background - the closest thing to a road bike in my life is my Salsa Fargo with a suspension fork. So, as I came on the team it has been my focus to get familiar with our non MTB bikes. The Ibis Hakka MX was my obvious 1st choice and I have taken it out on several rides from my daily 10 mile commutes, gravel loops in the Uintas and our Tuesday night group rides up emigration canyon here in SLC. Without getting into the details of the components I would just like to share my thoughts on this as an overall package and the feels I got while riding it.
As I said I am a mountain biker. I have raced xc and dare I say enduro. I once knew fitness when I raced in college, it may have only been youth however. Either way I do enjoy the work of climbing and will be competitive head to head if I feel the "snap." I do have to admit its all to feed the descent, I love the down. Anyway I digress, The Ibis Hakka MX feels amazingly stout and instantly familiar. It is compact (I am 5'10/11" and ride the 55) and nimble. It feels more like a mountain bike than I thought was possible, it is crazy stable when leaned over on pavement and even when my dumb little lungs are out of gas I can still shift down 3 gears and stand on the pedals to recover. I rode the bike strictly with the road plus setup with the Reynolds ATR wheels and WTB Byway road plus (45c) so it was in no way faster than the race bikes I encountered, But, I think it really surprised some people to see a flat pedaled, baggy short wearing, visor having mtb'er coming up behind them - or at times breaking away of the back (trademark CRK).
I love this bike. I get excited to ride it and sad when another Gearhead wants it. It could be built a true freeroad or gravel race bike, you could put a frame bad on and a seat bake and head out for the long weekend as a freeloader, or just double up the local RR tracks or potholes... In the end if your not a traditional road biker, are open to new roads and ideas or just want a ridiculously versatile bike (especially with out 2 wheel package) this bike RULZ.

Do both wheel sets include cassette and rotors? Given this is not an Ibis factory build is it possible to alter components? (include dropper and clutched RX)

No, this package build only comes with one set of rotors and cassette, which is part of how we're able to keep the price down, considering both sets of wheels are $1500 Reynolds wheels.

This SKU comes with one cassette and one pair of rotors. We can add additional parts at the build price.

We can also alter the build with the mentioned parts or others

Is this configuration of the Hakka MX available in the Coal color? Thanks

Hello, currently this option is not available in the color coal, but I'm happy to reach out to you about the possibility of a custom build that would make that a tangible item for you. But please feel free to email me at in the meantime if you have anymore questions!

Since this is a non-stock package build, substitutions can be made, including frame color, assuming we have the Ashen Black frame in stock in your size.

One of the most appealing features of the growing allroad trend is the ability of most frames to run 700c/650b tires. With those two wheelsets, you can truly go anywhere. I ran the 650b wheelset to get a feel for "road plus" - a massive 47c tire - which I found to be best suited for touring or other endurance events where comfort trumps weight. The WTB Byway tires are a great choice for mixed surface riding, but I might consider something a bit knobbier for trail-only conditions. Those wanting a more rugged setup should consider swapping in the clutched Ultegra RX805 rear derailleur.

Having two wheelsets offset the respective shortcomings of either wheel size. With this package, you truly can go anywhere.
