    Joining the Mojo ranks- could use sizing help between L and XL

    Hi,

    Looking to move from a 2009 Giant Trance X2 to a mojo hd and believe a large would be perfect but after searching and seeing folks in this forum even down to 5'11" on a XL want to make sure I'm making the right decision.

    I'm 6'2" with a relatively long torso (wear 32" inseam pants, yes I know this isn't true inseam but not sure what mine is). Style wise I come from a downhill/freeride/urban background though have slowed down (some). Still I wheelie and manual all sorts of trail features and wouldn't be okay on a bike that didn't feel playful and jump well.

    That said the mojo will be as close to a 'do it all' as I can get so despite being on flats 80% of the time there are some longer XC days.

    On my trance I'm on 711mm havoc bars and a 60mm stem and things feel good aside from the twitchier geometry.

    What do you guys think on the mojo?

    Thanks very much, looking forward to meeting some of the local Southern California (I usually ride at Aliso) Ibis members.

    I just got my Mojo HD - size LG. I'm 5'11' and built similarly to you; longer torso. It's a very good fit for me. Of course try them both if you have an opportunity, but if not, go XL.

    As always, finding a shop that sells them, and sitting on them is best. Since you asked though... I am 6'1" with a 32" inseam. I am on a large HD140 with a 75mm stem. When I first built the bike, it did feel a little small. I have gotten used to it now, and love it. If you are an inch taller than me, and going with a 60mm stem, you might be just fine with an XL. Let us know what you decide, and how it works out.

    6'1" with 34" inseam riding a L.
    Previously had an XL.
    Both sizes work, but the smaller size is way more fun to ride.

    6'2" with a 34" inseam. Xl with a 70mm stem, could never imagine riding something smaller, would be mega cramped. Most people who sit on my bike are always shocked its an Xl, Ibis sizes the bikes on the small size. Go with the XL and never look back. Sure you can run a L and ad a bunch of spacers under the stem and have the seat post looking like a giant extended dildo, but if you want the bike to fit correctly run the XL.

    Thanks very much for the feedback, will swing by The Bike Company and see if they have L and XL built. I have a large trance x and the feel is great, geo wise the L seems closest were I to run a 70mm stem on the Mojo.

    Only worry is getting back over the bike and getting it dropped sufficiently on tight switchbacks were it XL. For those who are on or have had who've replied is this an issue?

    I am not your size but I'll share my experiences. I am between sizes really

    My first mojo classic I opted for Med. Where I was riding at the time the shorter cockpit was not evident. Once I moved back to New Zealand and started riding on a lot more consistently steeper grades the med classic was too short. I have now got a Large and I am 5'10/11 with 32/3 inseam
    Originally I figured I could always make my med larger by running a longer stem. Not so sure thats the right way to go. I like the large a whole lot better but I am def on the shorter side for that size as I ride with three other guys- all running HDs and they are all on larges but running 70mm-90mm stems where I prefer 710-750 bars with a 50mm stem. I am not a climber!

    Hi!

    I am 189cm or 6,2 Ft. Inseam is about 89cm or 35 inch. I ride an XL HD with 60mm stem and 710cm bar. Bike fits perfectly in my taste. Never demoed or rode size L. I hate tall seatposts. I think HDs size XL is rather small for an XL frame as stated here in previous threads.

    Best Regards

    I have a large trance x and a large mojo sl and the Ibis feels a lot smaller. I originally had a med mojo but was way too small. My large rides a lot better. I am 5 "11.
    Go with the xl with a 50 to 80mm stem.

    If you can, ride both. If you can't ride both, ride a variety of bikes with different effective top tube lengths. Your Trance has a 24" ETT and the Mojo L is 23.6" and Mojo XL is 24.4" which is the same situation I was in. The ETT of my old bike was right inbetween the med and large Mojo. I was only able to get my hands on a large Mojo to test, but I tested a bunch of other bikes and decided to go for the medium and I'm happy (I'm 5'8"). I liked the feeling of riding more 'on' the bike as opposed to 'in' the bike. If I did a lot of bombing down straight hills, I may have gone larger, but I ride a lot of tight stuff and love the feeling of being able to whip my bike around.

    In your case, I would guess a XL as your torso is longer. But it comes down to your riding preferences. A lot of people like relatively short stems and wide bars on their Mojos.

    The problem you may have with going XL will be with adjustable seat posts. When I had my XL I was barely able to fit my ks950 on there. With the large I have about 1.5 inches of additional post showing. With your shorter inseam it may not work.

    This was my concern as well, I also like a slammed seat (I have an old 9" adjustable RASE post in my trance x and due to the seat tube bend can't get it down the last 2" or so and it drives me nuts)

    I read some of your other posts re the L being a better move and I'm thinking that a L with a 70mm and 750mm bars might be the ticket.

    Still will definitely try and ride both - hate being in the middle, the Nomad C was real clear - Large. Still know I'm going the better route for me with the HD.

    Compare the Ibis sizing with what you have now in top tube length and reach. And if it doesn't match up closely, or you want a change in fit, go longer for more stability and higher speed riding, and possibly a little shorter for mostly tight and slower, more technical riding.

    Given the same fit, the slacker HD steering angle lengthens the wheelbase increasing stability over a shorter travel XC bike.

    I'm 6'0 with short 32" legs , and long 34" arms. Very well balanced on a large with 70mm stem and 750mm bars. No way would I want an XL unless there was mostly higher speed riding where I live, but it's way to crowded in the SF north bay area for that.

    At 6'2", you are probably better fit on an XL with a fairly short stem.

    Top tube length can be deceiving based on seat/head tube angle. I like to feel centred on the bike so I use a long vertical level from the bottom bracket to the effective top tube position and then I measure from there to the head tube. compare that measurement with your current bike.That should give you the "reach" and then use various length stems to get the right feel and balance on the bike.

    Yup, the HD has a slack seat tube angle and relatively slack headtube which positions you farther over the rear wheel. If you like to be farther forward in the cockpit for steeper climbing, it will feel much shorter when you scoot the seat up. The HD is a relatively short bike in wheelbase and top tube/cockpit area compared to other bikes. Likely because of Ibis's appeal to many xc riders, so people who still like to run xc length type stems are not ruled out (even though they should be buying a slr if they like boner-stems). Having a shorter bike makes the bike a lil more nimble and fun which is a reoccurring theme in their bikes. Instead of buying a bike down a size to get the smaller more sporty feel, you get the proper sized frame and that feel is already built in (small sizing)

    Personally I think anyone over 6'+ tall who's rides all include pedaling should be on a xl. 6' and under get on a Large.

    I'm 6'2" with a 34" inseam. I rode a L and an XL before I ordered my frame, decided to go with the XL. I'm coming off a L Giant Reign X and the XL Mojo felt much roomier.

    Thank you all for the help, still torn but will ride both. Would a XL with a 45-50mm work?

    Also planning in running a 170mm X Fusion Vengeance HLR DLA (when released)

    If you're going to go XL with a 45 you'd be better off going L with a 70. I've run both and the fit is about identical. What I found with the shorter stem was the front wheel felt way far ahead. It was great for steep DH, but sucked (for me) for 99% of the riding I do. I was having to force my weight forward to be balanced on the bike in corners. You have a longer torso, so the XL could be a better fit.

    Maybe you can post up where you live and someone local may offer a test ride.

    45-50mm stem is pretty short for just about anything if your'e riding trail. Sounds to me like you want a Large if you don't mind a cramped ride, since you like a small dirt jump like bike that manuals, you ride flats, and don't pedal too much, the large may be the way to go. You need to ride them, I had the same questions but when I sat on a Large it felt so tiny I instantly knew I needed a XL

    I looked at the Mojo SL last year and demoed it 3 times in both large and extra large with a few different stem lengths. I'm 6'1" with a 35 inch inseam. I was smack dab in the middle of the sizes and was leaning towards an XL with a shorter stem (60-70mm). The large was too short to run a short stem. If you aren't completely set on a Mojo, you might want to check out the Pivot 5.7. The large size is in between Ibis's large and XL and fit me much better.

    Hi All,

    Great thread!

    I am just about to order a HD160 and am stuck deciding on size?

    I test rode a L with 70mm stem and 750mm bars. On occasions I felt cramped, but on fast singletrack it felt better. Even gnarly downhill slab sections felt ok?

    I am 6.0 and have a 35" inseam. The seatpost on the L was/looked ridiculously high!

    I am coming off a lapierre zesty L with a 50m stem 25 degree rise and 710 bars, which was beginning to feel comfortable. The Lapierre TT was 615 vs the HD L at 604mm. The XL is 625mm?

    At only 6.0 but with long legs can you visualise my position/reach. I.E tall seatpost but not needing to reach forward so far, hence the high/short stem.

    Thanks for any feedback.

    The next headache is the colour choices!

    Cheers

    Shameless bump on my last post! I cannot post my own thread yet

    I keep reading posts of people who are 6'/6'1 getting a large.

    As I said above, I'm 6'0 but with long legs and a 35 inseam. The L demo ride just felt occasionally cramped with the 70mm stem it had.

    Is my order of the XL the right one?

    Any feedback really appreciated.

    Thanks.

    Medrep - I ride an 160 HD in L with setback dropper post, 60 stem, 720 bar - and am precisely your size: 6'0 with 35.4 inseam (1.84m / 90cm in my numbers). I love my bike for sure.

    That said, I demoed an XL some months earlier and was quite happy with it, too. There were some issues with wrong tires and too firm shock setup, which added to the overall feel, but it still felt great.

    I finally chose the Large, because I wanted to have that extra agility - although that's more I read about than I feel about. My skills are ok, but I am not that super technical rider reaching the limits of the HD.

    I still think of the XL from time to time. The longer wheel base gives you even more confidence on descents. And on the XL you will want to use a short stem as 40 or 50, especially with a wider bar like that 750. And that shorter stem again helps you in cornering a lot. Put your saddle as far to the front as you can, use a straight post without setback and you're fine. I'm sure you will love your XL!

    Brilliant feedback, thank you!

    It was on a long fast downhill fire road that the L felt like it was really sketchy underneath me, and, the occasional feeling of being cramped on certain sections of trail. There was a black run section where there were slab drop offs, berms, very steep drops, rock gardens etc and the L felt great?

    I am now a fan of shorter stems so I think I will stick with the XL and maybe sacrifice the agility as you described.

    I am not the best rider, but starting to become more adventurous hence the move to a HD160.

    Thanks again for being a check and balance for my sanity!

    We are about the same height and I'm running an XL. I just switched out the stem for a 40mm and now the it feels perfect. The large had a cramped cockpit which I didn't like.

    Great, thanks!

    Its so difficult having not sat on an XL, but sitting on the L just does not feel 100% right, and that was with a 70mm stem.

    Thanks for reply.

    Yup same experience, sat on a large and it felt like a medium since ibis sizing tends to run small.

    Confused about "Smallness" of Ibis HD

    I should preface all of this by saying the topic of this thread is interesting to me as a possible HD owner in the future, but I do not think anything larger than a Medium is for me.

    I find it confusing that the Ibis is considered small for it's class. Is this a function of the larger sizes only? I have been eyeballing the HD for some time now and as I compare and consider alternatives I created a table (see below) to compare the geometry of my top choices. This seems to show that the Ibis is average to larger than others out there. My one complaint in the test rides I have done (Outerbike and several trips to bug the LBS with Ibis on their roster) was the taller stand over height. Am I missing something? The measurements that, in my experience, seem to have the greatest effect on fit are stand over and effective top tube length. I'm just one guy talking here, but the HD is tops in both of those categories. Perhaps stand over is less of a concern for those in the over 32" inseam set. I am 5'9", I run about a 31" inseam in pants (which I wear while riding so why not consider them?) so the almost 30" SOH on the HD is a bit nerve wracking (pun intended).

    All measurements are for Medium frames. All measurements are imperial (where applicable) *=greatest value in category
    Carbine Tracer 2 Mojo HD Nomad Dixon
    Wheel Base 44 44.2 43.8 44 44.5*

    Any thoughts?

    For the record, ended up with a XL which I picked up today. Details here: Mojo HD Picture & Build Thread

    Thanks again or the help/feedback, XL was for sure the right call.

    I'm 6'2" with a relatively long torso (wear 32" inseam pants, yes I know this isn't true inseam but not sure what mine is). Style wise I come from a downhill/freeride/urban background though have slowed down (some). Still I wheelie and manual all sorts of trail features and wouldn't be okay on a bike that didn't feel playful and jump well.

    That said the mojo will be as close to a 'do it all' as I can get so despite being on flats 80% of the time there are some longer XC days.

    On my trance I'm on 711mm havoc bars and a 60mm stem and things feel good aside from the twitchier geometry.

    What do you guys think on the mojo?

    Thanks very much, looking forward to meeting some of the local Southern California (I usually ride at Aliso) Ibis members.
    That's coincidental. I also moved from a 2009 Giant Trance X2 to a Mojo HD! I'm 5'10" and after I worked out all the geometry etc I went with a Large. Definitely for you I'd go with an XL.

    Agreed. If you're 6' or over I'd definitely go the XL with a shorter stem length (<50mm). Much better than going L with a longer stem.

    Just an FYI -I got an 'L' as my replacement frame. I rode the XL and it felt fine but in the end I decided to go for what I was already familiar with and best suited to the terrain and trails I will be riding. I will experiment with a couple of different bar widths and stem lengths.

    I'm 6'0.5" on a Large w/ 80 stem. I like being able to get my weight over the front wheel on long climbs. For descents... dropper seatpost to get my weight back towards the rear of the bike.

    I certainly couldn't get a good feel for the XL. All preference though.

    Just to update, I collected my new HD Friday and it is an XL with a 50mm 25 degree rise stem, 720mm bars. The fit is absolutely perfect!

    I am so relieved, as the only experience I had was with aboard a demo on a L and 70mm stem with 750mm bars.

    I found the Large size on my lapierre zesty with the above comonents felt ok, but I could never get my weight over the back easily. The ibis feels spot on!

    Thanks for the advice! My first real maiden voyage is tomorrow!!
