You probably can run 650b on most disc bikes, but you don't really get any advantage on some of them (like the Warbird) because of the chainstay shape.  

The idea of the having 650b is so you can run wider tires than you can on 700c.   This assumes the chainstay shape supports this.

On some bikes, the chainstays actually get narrower as they move away from the bottom bracket, meaning that you can't get wider tires on the 650b wheels.  

The Warbird was on my shortlist of new bikes this offseason, but after seeing them in the local shop, and discussing wheel options, I elimated it when I realized I couldn't run 650b with anything wider than about 35c or so.


Ah...good points.

In theory, yes, but it reportedly negatively affects handling on some bikes that weren't built for smaller wheels.  For instance, Trek pretty much strongly discourages purchasers from using 650b wheels on the Crockett.

Bring it on Trek! The gravel season is coming quick and the other bikes I'm looking at buying are selling out. If you don't come out quick I'm going to have to snag one of them.

Imagine staggered chain stays, stranglehold dropouts, dual IsoSpeed.

I'm thinking (hoping) Cutthroat rival

Crockett & Boone are already close to Warbird.

I check Trek daily.

[rofl][rofl][rofl]  That really got me laughing!  I saw Specialized went back to threaded for some of their mtb's and Chris King proposed a the new threaded T47 which essentially is a threaded oversized BB.  T47 has the advantages of the large diameter hollow axle, more bearings, but preserving the simple and reliable threaded installation.

I've given up hope of manufacturers ever going back to threaded BB's on 'performance' bikes.

I've given in to just installing threaded BB/Adapters from Enduro Bearing/WheelsMfg/Praxis, etc...  They seem to do the trick.

Won't be on dealer site, but there is an unveiling in Colorado happening today. I would expect pictures to show up within the week

Honestly, I'd be surprised if they don't let the dealers know first.

They aren't letting dealers know first. I won't even see one until later this month

It's our primary market, so we urged them to let us see the bike before it goes on sale

It will have an elevated chainstay like the Stache to support tire clearance up to 48x700, larger for 27.5, only isospeed on the seatpost.

No. Lowered chainstay. Isospeed front and rear and sliding dropout

SL and SLR versions? I saw a the SL version a week ago but i don't recall them saying if they will offer two carbon lay-ups. I will say that the drop stay is interesting looking.

I don't believe there is an SLR version but don't quote me on that. What color was the one you saw?

Black on Black. Nice looking bike. Curious to see how the geometry stacks up to some of the other gravel bikes currently on the market.

Should be pretty close to the crossrip. Damn I was hoping you saw a different one
