Ibis Mojo HDR3

Ibis’s new bike is a 160mm 26″ Mojo HDR. No, wait. It’s a 130mm (or 150mm) travel 27.5″ Mojo HDR. It’s both?

Built as an evolution of the Mojo HD, the HDR in 26″ mode has the exact same travel, geometry, and suspension but the ability to add 650b wheels is new. As Scot Nicol pointed out, you can have it both ways. The HDR is more than just a new wheel size though, as the frame has received quite a few updates to make it lighter and better in many ways.

Go both ways on the HDR next.

After Andrew Whiteford got an early release HDR 650b, his first response was “First ride… holy S#!t this thing is unbelievable. KOM on the way down.”

After thinking about the new HDR for around 18 months, Ibis wanted to incorporate some of the success from their Mojo SL-R into the HD including improvements in molding that resulted in a lighter bike. The HDR is about .3 to .4 lbs lighter than an HD depending on the size and color, but is stronger and equally stiff. Moving the linkages around meant they were able to add ISCG 05 compatibility and added more front derailleur compatibility as well, with increased clearance for the new 11 speed cogsets. The HDR will now fit Fox’s new lighter weight XV CTD air cans, and piggyback shocks.

After converting an HD 140 to a 650b bike, the Ibis team like the results, but the BB was too high and there was basically no mud clearance. After realizing very few changes would be needed to make the HD 160 work, the decision was made.

As a 26″ bike the HDR can run a 160-180mm fork depending on your use. With a separate set of Limbo Chips and a shorter shock (same as the Mojo SL-R), the bike will be set in 130mm travel with plenty of clearance for 650b wheels. Ibis states that if you want more travel in 650b mode, you can add a 5mm travel limiter to the shock with the frame in 160mm mode and it will limit the bike to 150mm travel – just make sure your tire will clear the seat tube on full compression.

Tire size is limited to 2.5″ in 26″ mode and most 2.35″ 650b tires. In the name of better protecting the frame and components on a frame that is sure to take some abuse there is an optional polycarbonate cable guard that bolts to the down tube to protect the brake and shifter housing as well as a considerably beefed up lower link with dual row angular contact bearings for the front of the link. Frame will be available in Reverse Vitamin P (above) or Cobra Blue, with Black, Red, or Blue links.

A word from Ibis on the geometry:

Our stock 650b setup (geometry below) has a 140 fork that gives you a 67.1º angle and a 13.5″ BB.

With a 130mm fork you get a 13.4″ BB and a 67.6º head angle. Both measured with Pacenti 2.3 Neo Moto.

If you want to run this bike in this dropped travel mode with 26″ wheels, that works fine too, you’ll get a 68.1º head angle and a 13″ BB.

You can also set it up with 26″ wheels and 160mm of travel on the rear, and 160 to 180mm travel up front. You can see that geometry over on the HDR page.

If you want more travel in the 650b mode, you can do that. Simply add a 5mm travel reducing spacer in the stock 160mm 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.

  1. I’d heard that they had a 650b bike coming. this is truly disappointing. Given the length of their design cycle, i’m wondering if we’ll be seeing a legit 140-150mm travel 650b bike before 2020. And for god’s sake, make a design that incorporates a water bottle cage inside the frame.

    How can SCB be so much further ahead?

  2. Packfill- What’s not legit about this bike? Ibis clearly states that it can be run with 650b in 140mm or 150mm. And why does Ibis need to sacrifice this design to incorporate a feature that 95% of their customers won’t use? Just curious.

  3. @RickyBob- this is nothing but a new Mojo HD with a band-aid to make it 650b “compatible”. it’s 130mm in the rear with 650 wheels. I want a 650b enduro bike with 140-150mm of travel, like the Bronson. I was hoping to buy a DW link bike, but strike one for Ibis. And, I completely disagree with the your statement that 95% of their customers wont use a cage. hell, look at their own brian lopes…dude runs a cage on the bottom of his frame. That doesn’t swing so well here in CO. I hear Giardia is a bitch.

  4. 100% on the side of @packfill.

    This is completely dissapointing. There was such a lack of 27.5 thought in the design the rear triangle can only accept 2.35 27.5s.

    I’m glad to see that front derailleur issues have been sorted out. This bike should have been released years ago to solve those issues but doesn’t answer any of the 650b issue they have.

  5. Tranny needs longer legs! Please tweek the Tranny Ibis. The bigger hoops should still fit in the travel case (with the air out of the tires).

    The HDR is sweet! Congrats and I hope I get to ride one with the bigger wheels.

  6. agree with packfill – 650b w/130mm out back is a total waste in this platform. 150mm minimum and throw an optional shock upgrade while you’re at it.

  7. Cool to me – but without a regular ol’ water bottle mount inside the frame, I won’t buy one. Spent too many years pedaling to school with a backpack full of books to carry water on my back mounting biking.

  8. “Same stiffness”? Thats disappointing. Oh wait, they will have a lopes link band-aid coming soon that wont make much of a difference.

    Sorry Ibis but this is a miss deep in the abyss

  9. Hey Texast,

    You obviously haven’t ridden the current HD or an HD for that matter, it is one if the stiffest bikes on the market. Save your hate for something else

  10. Don’t want to be a hater and I haven’t ridden the old HD but when they say “new” bike I was hoping for something truly new. Ibis are not the only ones doing this. “New” bike coming… Oh no, it’s just the 26″ bike with 650B wheels. Evolved bike more than new.

  11. \yawn

    never loved my mojo sl – poor rear end stiffness even w lopes link –
    weird handling
    i never quite understood the hype around that bike

  12. That deflate the shock to make sure you don’t kill your brand new $2700 650b bike part? It’s not even worth mentioning. That’s so completely unacceptable that I thought it was a joke.

  13. This is pretty half-assed. SC can produce two frames with FULL 650b compatibility and Ibis just goes backward semi-compatible. My Intense Carbine 275 is 150mm with full 650b compatible, even though it started out as 26″ wheel bike.

    Ibis obviously builds a great bike, but this is not how great bike companies should operate. They should have engineered a new rear triangle that works with existing frames.

  14. Ride the HDR in 650b mode and you’ll know there’s nothing disappointing or half-assed about it.

    I’ve been fortunate to have a HDR since the middle of May, and have alternated between 26″ 160mm and 650b 130mm. I was skeptical of the 650b but have been blown away by it on the trails. Back to back, it isn’t even close for me – the 650b is hauls ass. Plus you’ve still got a killer 26″ AM bike option if that’s the way you’d like to go.

  15. What is this obsession with more and more travel. I thought we are all past that stage. Pick as much as you want. More is not better.

  16. @Packfill: if you do not check seatstay clearance when installing a new high volume tire you are an [deleted]. Not all bikes fit all tires. All that a company owns to you is that the one they ship on a complete build fits.

  17. I agree with mindless (surprisingly). I think it’s nice that they tell you to check the clearence, instead of leave you to find out later (wich a few companies have no problem doing), and 130 on an HD frame is a good move IMO…good work Ibis!

  18. I personally appreciate the design that Ibis went for with the HDR.
    The Mojo as i see it is one of the most versatile bikes on the market, just take a look at Santa Cruz, they have the Solo for 650B with 125mm travel, the Bronson 650B with 160mm & lastly the Nomad 26″ @ 160mm.

    the Mojo HDR can be specced out to accommodate all these bikes in one frame.
    Run it in 130mm 650B mode to resemble the Solo, or switch up to 150mm with 650 wheels to get it similar as the Bronson, or even 160mm with 26″ wheels like a Nomad, you can even go up to 180mm up front for those hucking days.

  19. To be fair, making convertible design with axle chips (like Intense, or Banshee) is a better solution to the shock mount position adjustment. It allows to adjust wheelbase and ride height independently.

  20. @Alex: I couldn’t agree more. I like the versatility of the HDR, probably the most versatile bike out there, but until that top tube gets a little longer it won’t even be on my radar. The having to check tire clearance in 650b 150mm mode is not so great either. I don’t see how this redesign is going to sell a lot more HD’s other then to those who already have or wanted the bike.

  21. I love IBIS bikes and have been patiently waiting for them to release a true 650B option HD /HDR . They did do an awesome job on this bike but it still falls short of my 650B aspirations. Like others said, to me this is not what I wanted. 150mm front and rear and and truely designed for 650B. I still will check it out / ride it when it comes in locally and see what others are saying who have purchased it. One of my other peevs now that we have come so far along in bike design – WE NEED INTERNAL CABLE ROUTING IBIS! I love and want that clean look period. No excuse, get it done. I will pay a little more for it.

    My hopes now lie on the Rocky Mountain Altitude for 27.5 or still the 29 Specialized Enduro. I will be riding the Rocky mountain later this month and hopefully Specialized releases the 29 Enduro SE to dealers soon so I can test ride that one also.

    Hopefully I can replace my tired but still awesome and maintaing 10+ year old Yeti ASX with a bike that truely worthy of replacing it! I am sure going to drop some serious cash on my next bike and I am not going to settle, I want it all. Performance, weight, internal cable routing, remote adjustable seat height and remote adjustable front / rear shock settings at the same time(the Rocky MTN altitude has all that, just need to do a serious test ride). I can live without the internal routing but that’s icing on the top for me.

  22. @rickybob- you are correct sir. i went to the bahamas there,sorry. fair play. however, this rig needs a coil or a much better compression tuneable shock than that fox. ccdb air or start w/ monarch plus. 650b in 150mm/160mm mode should get you rolling in chunk without having to compromise tire size for grip. wonder how the blkmrkt roam does with the interchangeable wheel sizes.

  23. What’s the bottom bracket height with the 650bs at 150mm of travel, 14.25″? I’ll pass. Please make a real 150mm travel 650b bike.

  24. Dang…I have very mixed feelings about this bike….It was kinda what I was hoping for ibis to come out with…but it just feels very rushed….just to get on the bandwagon…I mean, the Ripley took forever, but look at it…look at the tech…it’s a DEDICATED 29er trail design!

    130mm is perfect for me, don’t get me wrong, but I don’t know, everything feels like forced to me….take the santa cruz SOLO for example….dedicated 650b trail bike, period. This…not so much…I’ll just wait for Intense to put out a 650 Carbine SL out.

  25. I have been riding a 650b mojo hd in 160 mode with a shim in the shock for a year now and it is the cats pajamas. I had a chance to demo a SC bronson this weekend and I have to say the mojo blows it away(and also blows it’s cousin the ripley out of the water too). Just sad that they won’t sell me a rear triangle to retrofit

  26. I have no use for the latest wheel fad, and could care less that the frame is 650b compatible. it’s funny to see the 29er hype recycled. Bike companies have to sell new stuff to make money, but after 40 years of riding 2 wheels in dirt, I just don’t fall for the marketing. I’m waiting on my 4th 26″ $2500.00+ frame in 3 years to build up as I type, so obviously I can ride whatever…and I’ll be sticking with 26″. After I find out if the HDR has mud clearance for a minion 2.5 and a CCDB coil, I may try one out.

  27. Launch of HDR 650b sanctioned frame is a bit of a joke to me also for the following reason….I recently converted my 2011 Mojo SL to 650b and during conversion had to shim my rear shock from stock standard 140mm to 137mm travel to allow 650b tyre clearance inside rear triangle. I have longer rear travel on my 2011 SL 650b conversion so why would I chose to purchase a 2013 HDR 650b frame with less rear travel (130mm) than I currently have on my 650b SL (137mm) haha , )

What do you think?
