Was looking at those the other day. Really psyched on that acid wash finish!

Thank god. I was shopping for bars and stems but just didn’t feel like there were enough options. This might just be the perfect one.

Absolute game changer. 

Imagine producing a new alloy bar and stem combo and not going 31.8mm🤦‍♂️

i wonder why with so many options of bar/stem/pedals on the market but influencers/companies looking to produce some kind of custom kit/part will still automatically default to one of these. Is there a lot of money in these somehow, or the manufacturing process for these are so dialed it's really easy to just order a custom one?

35mm handlebars are stronger and lighter than 31.8 for the same stiffness. The first 35mm bars in like 2012 may have been overly stiff but minus a couple of outliers that hasn't been the case for the better part of a decade now.

Reece Wilson on the BMB Raised Reversed stem

https://youtu.be/Lv2dSlxHPYA?si=9cXbgcvrMo0CXnfR

Reece certainly has a bit of history with kooky setups, but pairing that stem with a large reach and chain stay certainly makes a lot more sense than just putting it on your normal bike. 

Not something that many people can easily test, but maybe something that if he does well on it, it might make more people who do have easy access to bikes of different sizing might try.

I dunno, I haven't tried any of them. He certainly has a similar idea, and Reece was already using Rulezman stem.

Just because he's cringey af doesn't make him wrong lol.

I just thought it was an interesting video from a high level rider

If designed to the same max load, a 35 mm bar is approximately 10% stiffer. The required cross sectional area of the 35 mm bar is also smaller, so it would be lighter. Below is an example where the bar is evaluated as a basic cantilevered beam where the length is 400 mm and the load is 450 N. r1 and r2 correspond to the 35 mm bar and r3 and r4 correspond to the 31.8 mm bar.

To jump on this having dealt with spec'ing and getting bars to market, the 35 is stiffer than you will get out of a 31.8.  

Strength, at max strength 35 may be stronger, but trust me, we aren't getting near failure for either, at the end of the day, weight and flex are bigger issues for the industry than brute strength. The combo does play in.  but with the increased need for better ride quality across the industry, 31.8 is very much a viable standard and what most of my riders actually want out of a bar.  This includes many PMs...for their personal bars.

BUT, the 35mm bar matches the aesthetics of a a large tapered headtube better for sure. and that matters when selling bikes

A bit of both.  Compared to a lot of bike parts  the entry costs are lower and the mark up can be pretty high if you are shooting to be a “premium brand”.  Also relatively cheap to ship and store.  Same goes for apparel.  

Not sure what happened with title and Brett but he did a great job launching that brand.  I wonder how many outside of bike nerds even know signature exists and that title is no longer associated with Brett.

Ibis is planning to release a Ripley SL in a 120/130 configuration. Will lean more XC than the current Ripley (130/140). Release is expected around April, from what I've heard. Was unable to find out if the HD6 was going to be offered as an all-29 option. 

Good to know. Did also hear some rumblings of this. Maybe they will beat Forbidden in the color game. Stoked on another non-flex stay option. 

I do love my Druid and Dreadnought, so the longer stays have a place in my heart, but the black and goldish options don't spark joy like the pink druid for fatty t dread. Weight will also be something to wonder about with Forbidden. 
I also probably never realized that part of the reason I loved the Banshee Phantom was the 445 chainstay. Hated that I could only run a 170 post on the XL, though. 

April and Sea Otter can't come soon enough for all this new new stuff.

The Signature stuff is really nice but the costs skyrocket due to import fees getting it into the US.

Doesn’t that comparison assume uniform cross section/stiffness across the whole length and neglect the fact that both taper to the same diameter fairly quickly? The flex will be distributed across the whole bar, not just at the stem interface.


I would imagine that taper profile might actually be more important than just clamp diameter. I remember my old 31.8 Boobars had a weird profile and didn’t really taper until right at the controls. Most of my 35mm bars seem to taper pretty quickly.


It would be interesting to model a few bars and do some analysis on them.

Yes it does. It’s just to show that a larger OD is inherently stiffer for the same load rating. You could design a thicker bar to quickly taper but then you have yo ask yourself why start so wide to begin with.

Tomorrow I’ll whip up some sort of comparison. Deflection can be analyzed by integrating across the width of the bar so if the outer 75% of a 35 mm bar were identical to a comparable 31.8 mm bar, the deflections would be identical over that length and the only difference would come down to that innermost 25%.

Those tests always drive me nuts when they attempt to do vibration/damping analysis.

I don’t think I’ve seen one come up with useful data for what they’re trying to prove/test.

I wish I could use the shakers at work for personal use. 😂

I find it hard to believe that this would be an Esker, simply because the design is more complicated than what is on brand for them. A huge part of their ethos is simplicity: Every bike they sell has external cable routing. Why would they do internal routing, especially if this was a prototype or validation frame? With how much the industry is struggling (Esker themselves have had a bunch of their bikes on sale, including their suspension bikes they just brought back this past year), I would be surprised that they would be trying to expand outside their core market. With that said, Priority also made the Vanth out of nowhere, so what do I know? 🤷IMG 1850 1

The only thing I can say is that every guess in this whole thread is flat out wrong.

Reece certainly has a bit of history with kooky setups, but pairing that stem with a large reach and chain stay certainly makes a lot more sense than just putting it on your normal bike. 

Not something that many people can easily test, but maybe something that if he does well on it, it might make more people who do have easy access to bikes of different sizing might try.

Meh, it doesn't do it for me, but experimenting is cool. My dh bike is on the big side for me and honestly I'd give the Rulezman stem a go, the BMB one might be a step too far for me though. Still, if somebody had one I could try for free I'd go for it.

i immediately thought its an Alu mule for the firebird. I dont imagine another bike company, no matter if its affiliated with DW-Link will blatantly copy the Pivot Phoenix layout, down to the flexstays. but hey, its my best guess. the dual idler gave it away.

So now it got me thinking, The Devinci Spartan hmm....that high pivot setup is a little dated now. ++hint hint, im also the one that spy shotted that proto several years ago on the same mountain++

And also the norco range haha
