I’m looking for some 650b tires (and wheels) to make gravel rides out of:
-          Girlfriends 27.5 mountain bike (stock MTB tires are way to heavy and slow)
-          My beautiful steel ‘90s race bike (wide stays, but not tall) that takes 700x23mm

Can’t find many choices for 650b road/gravel tires.  Most tires seem to be mountain bike oriented.  Any ideas?


650 tires in the 40mm range
Compass tires
Panaracer
WTB Horizon
Schwalbe & Continental?

 

Panaracer Pasela PT Wire 650B x 42 tire, blackwall
Soma New Xpress 650B x 38
Compass Loup Loup Pass 650B x 38 (584)
Panaracer Col de la Vie 650B Tire 584 x 40mm

Panaracer Pari-Moto 650B x 38mm Folding Bead
The pari-moto at $35 on amazon, 280 grams. Dang!

While they should mount right up to the 27.5 mountain bike, I'll need new wheels and long reach calipers for the '90s steel road bike. But I'm just not riding any bikes that only take 25mm tires and a 650b 42mm tire has the same diameter as a 23mm 700c tire.

That's pretty much it. There's a couple other Soma 650 tires - Grand Rando and B-line. And there's the Grand Bois Hetre that Compass sells.

Panaracer Col del la Vie is an option, Velo Orange carries it.

Schwalbe has the Marathon Supreme in a 42.

You can also get the Hutchinson "Confrerie des 650b" 32 from Europe.

The Panaracer Pari-Moto looks nice, but I started reading reviews of the Cannondale Slate, and everyone HATED this tire for its propensity to flat and prematurely end a ride.  It appears to be a Gravel King with no protection.  Not sure what the point of that is, other than to save $$$.

The slate looked like an interesting bike - road bike geometry without compromise for larger diameter tires - since 40mm 650B tires have similar diameter to 23mm 700c tires.  Reviews were all over the place.

Of course the Road bike people thought it was too slack,
and 
the dirt/gravel crowd thought it wasn't slack enough.

I have had the best luck with Schwalbe G-Ones(40mm) on the Slate..no flats...running tubeless.
Have WTB Horizons, are good on packed gravel...my Elwoods can rub slightly on the back or very little clearance. They are a great tire however.

Another vote for the G-One.

It One has been great on the Slates for us. It is reasonably fast on the roads while still capable of some single track. We run ours around 40psi tubeless on Nox Skyline carbon rims (25mm internal width). The only exception to the "great" was that I did have multiple rear flats at the DK200. These were all sidewall cuts from the flint rock and I'll go with bad luck as the culprit.

For what it's worth, I had bee been waiting for the Clement MSO in hopes of better puncture resistance prior to our trip to Kansas, but still not available to buy. Then, at the Dirty Kanza, I saw Ted King running them on his Slate. He ran G-One in 2016 and had suffered some sidewall cut issues. Well, the MSO didn't fare any better, for I believe Ted had three flats with the MSO as well this year. In other words, flint rock will cut tires, just depends on how lucky/unlucky one is on race day.

Sounds like you need good sidewall protection for that ride, but a stiff sidewall is going to make for more rolling resistance.  I'm gonna guess it is only a problem for the rear tire...

Head scratching your bike. I'm not aware of any 90's road race frame that will easily accept a 650b 40c tire. Definitely not with any sort of aggressive tread. But if you find one that magically does fit, are you prepared to make a serious downgrade to the worst brakes ever (long reach) to accept said tire?

You are right, the  steel road race frame will stay on 28mm.  (actually tires marked as 25 or 28mm that actually measure 27mm, true 28 will not fit in the rear).  The rear stays can't take anything much bigger than a 32, and that isn't worth the effort and compromise.

I have run Kenda Flintridge Pro on my Raleigh Tamland and they are to have a 650b version by the end of the year...will go with G-ones until that is available. A very good gravel tire..no flats 2 years ago with Flintridge and none this year with G-Ones at DK ( lucky ) but I think the Kenda has better side wall protection and rolls pretty well also.

Regarding Panaracer/Parimotos....

- There are at least 3 different generations of the parimoto.  If you can get the most recent versions there is a bit of flat protection in them, supposedly.  That said, they are a bit heavier, though still under 350g for the 42s.  I have about 500miles on mine, run tubeless on dirt (not gravel) and they have been divine. I will say, however, that in my riding circle there are more than a few once used previous pacenti/pana parimotos lying around.  Really light... but... many many flats 

- There is is also a 'Gravel' version (not Gravel SK), that supposedly has bead to bead flat protection.  

Frankly, my fingers are crossed that in the next year or so we'll get some decent performance oriented options.  I'd love to see a 650b x 42 tubeless Strada LGGs or G1 Speeds/S1s.. or, hell, even Conti GP4000s, but that might be just crazy talk.

Soma makes the Cazadero in both 700c and 650b. I am running it in 700 and really like it. It isn't tubeless rated though and I tried mounting it tubeless with orange seal sealant and after a short ride and sitting overnight it lost 10 psi. It was seeping through the gumwalls. They were too porous for the orange seal to seal up so back to tubes I went. They are nice riding tires though. Another factor is to look at some of the 650 MTB tires with less aggressive tread. Maybe even some of the fatter urban tires. If your not racing and only doing recreational gravel rides then you can get by with street tread. I have done it on 650bx42 Panaracers with street tread and they worked just fine.

My wife has been on Soma Cazaderos on her 650b Straggler since we built it up. They're a really nice riding tire and roll pretty well. Saying that she's been spoiled by the Compass tires on her other bike and wants a set of those on her Straggler now in 650x42.
If your GF can get by with a fairly fragile tire the Compass are really spectacular.

If she can fit a 48 on her bike the WTB byway is what another friend runs and he's digging them a lot.

Thanks, I set up some thin walled Continental tires with orange seal.  Took about a week to get them to quit seaping (with orange seal).  I did it in the winter so it wasn't a problem, but they eventually did seal.

Interesting......Can anyone verify that this will work well consistently or did chas get lucky? I would be willing to try it again if I knew I just had to be more patient allowing the Orange Seal more time to fill the pores in the rubber. They sure pumped up with my hand pump and snapped the beads good just like a standard tubeless ready tire would so I don't think burping would be any more of a concern than a tubeless ready tire would be. Can anyone else relate similar successful experiences as chas has?

Someone, I think it was CX magazine, did this with compass tires (thin walled, non tubeless) and had a similar experience. 

I used skinny strippers to eliminate the potential of burping or catastrophic air loss.  It's cheap insurance.  They will bond with the tire and latex, in effect creating a tubular tire out of a tubeless tire.  http://skinnystripper.com/

I already have tubeless ready rims. My wheels are using Stans Grail. I called and talked to Orange Seal themselves and they said after sealing beads I needed to try riding more than I did the first time to get the tires hot so the pores open up. I may give this a shot again

Gravel King slicks are out in 650b x 48 now and they're officially tubeless compatible.  They might fit your GF's bike.

Thanks for the input. I found the fastest tire schwalbe be makes for 1/2 price. 60mm big ones.
