    Salespunk, I've noticed you on the Socal Forums. My wife and I are moving out to LA in a few weeks and I'd love some advice on where to ride, where not to ride, etc... Or someone to ride with once we get settled in. I've been checking out trail reviews, and socal forums, but nothing compares to someone who actually knows the area!

    So I/m 5'10 and I rode the M6 (during a demo) , Medium with a 65mm stem and felt good.
    The large was not available.

    I currently ride a Blur LT medium with a 70mm stem and feels ok.

    Should I be good with the Medium M6? I'm 5'10

    thanks for the input.

    I'm 5'10" as well (32" inseam) and honestly could have gone either way depending on what I was looking for.

    I demo'd a large at interbike and ended up getting a medium last week. The large felt just a little more stable but I had trouble moving around and behind the saddle. It seems like if you want a more all-around bike, go for the applicable size and if you want more of an enduro/super-d racer, you go up a size so it'll be more of a mini-DH bike like some of the other 6" 650b bikes.

    After putting 70 hard miles on it last weeek it didn't feel cramped at all, even though I put the 50mm stem and 740mm bars from my M5.7 on it.

    I am 5'10" as well with a 30 inch inseam and demoed a large a couple of weeks ago. It felt really good but slightly less flickable than I had hoped. I am going to try a medium soon hopefully but I would certainly be happy with a large. The large was very stable at high speeds which was obviously nice.

    You are in a good position because you could ride either size. If you are going with say a 50mm stem, then I would lean towards the large. I am also 5'10" and I think it fits me perfectly the 50. Also consider where you are going to run your seat. I am not a believer in the "KOPS" method of placing your seat. Keith Bontrager and others have debunked this having an effect on efficiency. However, the slack seat angle will make it harder to keep the front end weighted for a climb. You adjust to this pretty fast, but some don't like that aspect of the Mach 6. My seat is slid pretty far forward to compensate for this and since I have the large I had room to do so. I would have had to have the seat pretty far back on a medium.

    I am also 5' 10" and could have gotten a large as I am also between the two sizes.

    My medium M6 came with the stock stem, which I think it is around 80mm. Looking down at the front hub, the handlebars are just behind it.

    Here in San Diego, you are often pedaling to the top of what you are about to go down, so from that perspective, having the stock stem I think offers a little more control over the fork for the ups, and certainly offers enough confidence for the downs because of the head tube angle and the longer travel, so the medium is fine. By comparison, I would say my M6 with the 80 mm stem feels about 1/3 lighter on the front end than my M429C with a 70mm stem (again because of head tube angle and more travel).

    If you are doing more DH stuff, a shorter stem will put your weight even further behind the fork which I would imagine would start to get annoying if you do a lot of climbing. If I was more of a park rider, I think I would have gone with the large and a shorter stem.

    Having the medium M6 allows me to use the bike in more of an XC setting where I need it, but also allows me to use the bike in a more downhill'ish mode if I need that also.

    Mach 6 Frame size

    Wouldn't an extra 30 mm of top tube keep the front end weighted as much as 30 extra mm of stem? I would think so, but not 100% sure. The axis is the rear wheel, which is why a half an inch of chainstay length changes handling so much. I will take the easy manualling of short chain stays any day.

    I also have the option of running the seat further forward on the seatpost with the large, which will definitely aid in climbing.

    Most of the reviewers didn't like the long stock stem, but it's all a matter of preference.

    People need to stop worrying about the seat tube angle. It's actually steeper than a M5.7 and even the 429, and nobody complained about them.

    What's happened is that most of the other 6" bikes have steep angles because their suspension squats under power while the DW-link extends. They have to have steep seat tubes, Pivots don't...that's why all Pivots have slack seat tube angles.

    Mach 6 Frame size

    It may be fine at average height, but I can see it would be an issue for someone running a very long seatpost. Because of the virtual seat tube angle, you could have a much slacker angle than what it's designed for.

    The virtual ST angle is based on whatever they consider the average seat post extension for the applicable height for the frame...or somewhere around where people who buy the recommended size have theirs. Nobody is talking about going down a size, only up if you want a longer top tube.

    This is neither a Mach 6 or a Pivot "problem." They all have slack seat tubes and nobody spoke a word about it until someone reviewing the M6 looked at the website or brochure and said, "Hey, this is slack." They didn't say it didn't fit, put their weight too far back, couldn't climb, nothing. Now everybody acts like it'll flip over if you even look at a hill. The M6 was voted the most versatile in the MTBR trail bike review, FFS.

    I have a 50mm stem on my medium and it climbs steep sections just fine. It doesn't take much effort to get the front wheel up and over an obstacle, but it doesn't take any to keep it on the ground either.

    The above captures my thoughts/feelings on my Mach 6 vs my Tallboy as well. I'm just up the I15 freeway from him (Temecula), so I'm sure we ride similar type terrain.

    I'm 6'-0" and ride a Large Mach 6 with 70mm stem and 760mm bars. On my Large Tallboy I run a 80mm stem and 750mm bars. I feel both fit me perfectly.

    Looking for more info on this, hoping to get a few more "medium vs large" inputs. I'm 5'11" with a 32 inseam. Borderline on which size to get as I'll be running 35mm stem and 780mm bars. Right now I have my order placed for a large but have until Sunday night to change it before it starts getting built. Also will be going with a fox 36 @ 160mm instead of a 150mm fork.

    Coming off a yeti sb66 in a medium that was run with a 50mm stem and 740mm bars. That felt right at the edge of comfortable. Riding is trail with aggressive descents and the occasional 10-12 foot gap jump.

    Large makes more sename than medium based on your size.
    Safe riding,

    Idaho, I am 5'10" with a 30" pant leg inseam. I was on the fence between a large and medium and could have gone either way but ended up going with a medium with an 80 stem. The large felt very good and I certainly could have ridden it but the medium was more flickable and better for riding tight single track around my area. The large with a 35 sounds pretty much perfect for you. You are going to be very stoked on the M6. Stick with your large order.

    At 5'10" with a 50 mm stem, I love my large. Based on the stem you want to run, you are firmly in large territory.

    Thanks for the input. I will stick with the large I had intended on ordering and get it posted up in the Mach 6 build thread once it's done. Now just tossing around wheel ideas as there are an incredible amount of options!

    I'm 5'10 with a 32 inseam, and demo a medium with a 65stem, a bit to small for me.

    I ended up ordering a large which I am currently building iwith 750bars 50mm stem and a 160mm pike.

    Just waiting for my wheels in order to ride it.

    I agree with tadmcmichael. 5'11" running a large with a 50mm stem for about a year. Your 35mm stem on a medium would be far too small unless you were coming straight over from BMX with a strong lil bike preference.

    I'm 5'11, ride aggressively downhill, and there are a lot of steep technical climbs in my area. I was on a Yeti SB66c Medium with a 35mm stem and had 711mm bars. I had a 65mm stem on the SB and it felt too long for sure. 50mm probably would have been my max on a medium. I am now on a Medium Mach 6 with a 50mm stem and 760mm bars.

    I prefer more nimble bikes that are easy to jump and good in technical terrain over super long and slightly more stable rides so that almost always puts me on a medium frame. Over the SB66, I found the seat tube on the Mach 6 to be quite slack and it was hurting my back on the steep climbs we have. I didn't have this problem on the SB66. I switched quickly over to a 160mm Pike with travel adjust and that helped a lot, though I still feel it's an issue for me. I slid the seat quite far forward on the rails which helps as well. I think that's the main thing with guys 5'11 going to a medium - you are pretty far over the back wheel when your seat is at full height. The top of my saddle is 12.25" out of the seat tube at full height with clipless pedals. I have room to lower my KS LEV 150 post 2.5".

    If you are 5'11 and adamant about using a 35mm stem, I would say you should probably go with a large. A 35mm on my medium would be a touch too short and this is coming from someone who prefers a shorter cockpit.

    If you subscribe to the formula of 2/1 bar width increase/stem length decrease, a 35mm would be close enough with 780mm bars.

    I'm an inch shorter and use 750mm bars with a 50mm stem on a medium. No problems climbing and it seems to really rail corners with the rearward bias that an attack position gives. The hub is way forward of the bars when looking down, but it works. Best of all is that I don't have to have the saddle lowered to get behind it (and not get hung up in that position), like I did on a large.

    Seems to be a few conflicting reports but I settled on the large ultimately. Hope it works out as that's also what Pivot suggested when I called them. The said on this bike people will generally up-size where as they will generally down-size on their new XC bikes.

    Ended up with Chromag BZA bars at 780mm and a 40mm Haven stem as the 35mm Atlas from Race Face was out of stock.

    I believe you'll end up pretty happy with your build Idaho. I have the same height and inseam measures and built my Mach 6 with a size large frame, 780 mm wide bars and a 50 mm stem. It feels great! Very playful and easy to throw around

    Hi, I found a very good deal for a new small mach 6 frame, however I am 5' 10"
    I Demoed it, at first I felt it small as expected. then after a few adjustements of the seat and a wider handlebar I felt it better. Almost as my currently medium bike.

    unfortunately I cannot demo a M or L frame. so my question is if a size smaller than the recommended would be fine?. I want it for AM.
    In the geometry charts there is only 0.57 inches of difference in the top tube lenght.

    Wow 5' 10" on a small?? My GF is 5'6" and she could easily be on a medium...she rides a small with a 60-75mm stem.

    I'm 5'11" and ride a large with 65mm stem and could easily ride a XL. No way I could ride a medium unless I went with a 90-100mm stem which isn't a setup I'd want.

    FWIW - we ride techy tight AM forest trails in BC.

    Having said all that there is more to bike fit than height so if you felt okay on the small that's more important than 1000 internet opinions on bike fit.

    What size stem was on the bike you tried? If it was short at least you can put a larger stem on it. If it was a longer stem you won't have any way to extend the reach since you already tried some wider bars.
    Safe riding,
