New Mezzer inbound?

New Mezzer inbound?

Looks like it might be. Lowers look pretty much the same but the fork crown doesnt

Yeah, the lower casting looks to be the same for sure. The rebound knob is also different from the current version, though, so it will interesting to hear what changes may have been made to the damper.

Here we go, it had to happen sooner or later... The first ever production full-suspension carbon XC-Bike with 32" wheels.

Geometry table is at the very bottom of the page. Though it seems like Stoll won't tell you the full geometry data unless you're ordering a bike. They've got sizes "Medium" and "Large", although people have done the math for the missing geometry numbers and both sizes are very big. The size recommendations seem a little strange, to say the least.

Sorry, just realized that the contents of that website are, in fact, not available in English.

Now I'm sitting here, having a little laugh thinking about how jarring and discordant that word must sound to anyone who's not used to German pronounciation. 

English: effective top tube length 😊

German: OBERROHR 😬😠

One thing that became almost immediately clear in the relatively short time that I have been reading and participating in bike-related internet forums is that the proportion of posters that are good at math is extremely high.  It seems that 1 in 10 is an actual engineer, and the proportion of math-brained folks among the remainder is way higher than the public at large.  

As such, holding back geometry information strikes me as misguided because one's efforts are destined to be futile unless they also refuse to release pictures of the product.  From the moment the bike is portrayed in side profile, you may get one day before some mathematically inclined internet sleuth derives it all and spills your beans for you.  

Honestly, we're probably all just huge nerds.

Or maybe, the sad reality of it is that cycling in general is such an expensive and elitist sport that it mainly attracts people who are financially quite well off. And in most western countries, academic success is very strongly linked to financial prosperity. Rich people, statistically speaking, still have much better chances in academia and generally much better access to higher education. Therefor it is probably not a coincidence that people who ride bikes seem have above average education. 

I'd like to see a venn diagram on this sociology of cycling.

Stating the obvious here, but once either of the big 2 start shipping a production 32" fork is when I expect things to start really taking off.

(We'll need tires too, but I don't know how long it takes to bring a new size to production; anyone have any insight?)

What the hell is wrong with these companies? Both Stoll and DirtySixer think they can sell bikes without telling people the geometry.  Is this just some kind of rug pull because they don't know what they're doing, and until Trek or Specialized or whoever comes out with a sorted 32inch bike they can trick people into being early adopters with the alure of new-new (be the first on your block!)? This is some fly by night nonsense.

Okay, so we have carcinization for bike suspension, but is there a similar process for clip-in pedals where they all eventually use some variation of Shimano cleats? Spudification?

I remember CST and other tire manufacturer having no technical issue making 32 inch tires when asked during last Taipei Bike Show, the main issue is bike brand committing actual sizeable order for them and they would need to know that option from fox and rockshox are possible atleast for xc bikes.

32" front and back is only gonna be unequivocally better for people of a certain height or better, and peeps gotta keep it real in that regard. With the technicality of modern XC courses, a 32" wheel for someone too short is gonna be a liability I.M.O.

 

We need a new term for 32" front 29" rear. How about Mega-mullet?!

Makes sense to me; they won't need a new casting (maybe? Is the Lefty upper cast?) which should speed up development...

I think the bigger wheels will be faster for everyone, just like 29ers were. XC courses seem to be getting more jump / descend skilly and less slow techy, a perfect match for an even bigger wheel.

They might be able to limit the travel on the lefty.. Might just need a longer stanchion tube.. But, I'm not totally familiar with the Lefty internals..

Darren Baum already did this so I'd be shocked if Cannondale isn't all over it...


"Less easy was the fork, and rather than going the rigid route, Baum customised a Cannondale Lefty Ocho mountain bike fork (if you can call it that). “There’s no arch to get in the way of the tyre, but it had too much travel. The front wheel would have ended up hitting the down tube during compression, too, so we did some work in house to reduce the travel to 80 mm, which is what we were after for a gravel bike,” shared Baum of the customised air spring within."

I wonder if the SuperMaxx lefty competes with the more current USD forks? It certainly does in weight…

Unsure.. in downhill we went from 26 to 27.5 to 29, and then back to 29/27.5 - it kind of seems like we found the ceiling.

Lots of dh guys say full 29 is faster.  Just mullet is so much easier for them to make adjustments and limit mistakes that they choose to run the mullet.


Xc is an hr long plus race.  I’m sure we’ll see some people throw away a result in the first seasons of 32 wheels.  But I’d imagine most the field will be on them once they can.  The same way everyone ended up on 29.


Think it’s likely 32 will also lead to mullet setups being allowed in xc which was pointed out to me as not currently being legal.  But I think you might see shorter riders on 32 rear and 29 front to solve the stack issues before people are worried about eating a tire in their buttcrack.  It’s just not usually a problem on short travel bikes with long seatposts with generally short or no dropper.

Only time will tell, it’ll be interesting to see where it does end up. 
Personally I hope it dies a quick relatively pain free death and it doesn’t lead to bike companies sinking a heap of money into sub par bikes as has been implied previously in the forum.

Once we get a new axle standard to stiffen up the huge wheels, we surely know that the history repeats itself
