I try to carry a tiny bottle of tire goo every time I go out on a tubelessed machine, and of the two times I tried to use it it’s worked once (I got glass through the tread, and a lot of tire goo flowed out before it congealed, so I dumped the air out of the tire and topped the goo off before continuing; the other time I got a stone through the sidewall, and oh hahaha it wasn’t even close to successful. Fortunately I always carry a tube or two, so there wasn’t any sort of 30 mile walk of shame back to Portland that day.)
Well the compass tire seem to have finally sealed up again after 2 nights of sitting on each side letting sealant into the sidewalls. Going to try that nalgene bottle of orange seal to keep in my saddle bag.
Why not just buy a small bottle and Stan’s and keep it sealed (with a small valve core tool) until you use it?

Update on GK Slick 650 x 48s:
Pumped em up to 28psi and they’re doing better. Seems like a very small window of pressure for acceptable ride quality. Also finally brought them on some gravel, and they are much more confident than the Horizons were. Not gonna take them off quite yet.
Also on sealant chat, I do carry a mini bottle of goo with me but also think that if a puncture doesn’t seal up with whats already in the tire its worth just putting a tube in and dealing with the quantity of wet stuff later.
Resist Nomad 35?
This reminds me, I wanted to update my initial impressions of this tire. For the first couple hundred miles they were super slick and liked to wash out and slide on anything less than good pavement. Wet road lines and that sort of stuff was pretty bad on them.
After a few hundo miles they calmed down and started to actually be half decent though.

They did a 650b but maxed out at 28. 
I’d love to see what rims they recommend for it in 650b. (a 650x23b? Yeep, I tend to prefer narrow tires but something that narrow would just fall down and vanish inside any of the rims I’ve got.)
I mean it’s a traditional road race tire. I do kind of want to build up some skinny fast wheels and then remember I hate it and never ride them.
Use case would seem to be for microhuman sized road bikes a’la the XXS Canyons.
Nerds need not apply.

I’ve got two pairs of the 650x25b Schwalbes at home (they’re lovely fast tires) but if I go off-pavement for any significant distance (pnw+randonerdery) they burp themselves to death. Possibly some narrow rims would help, but tubeless + narrow + rim brake + 650b is the snipe of rim hunting.
Tiny wheel disc road. Most people don’t ride off of the roads.
Looks like Canyon has switched from Schwalbe to Conti for 2019.
I’m almost overwhelmed by the number of options for my wife’s road bike (prior to the Canyon, she’s been on 650c’s for years, dealing with the dwindling number of supple tyres.):
Schwalbe One 650b x 25
Schwalbe Pro One 650b x 25
Conti GP5000 650b x 25
Conti GP5000 650b x 28
Hutchinson Confrerie
Grand Bois Cypres (if still available?)
Donnelly MXP 650B X 33 might fit?
650c road bikes are a hard one. I see a few on the second hand market but the clearances are so tight any form of conversion is pretty much rub city.
Bad news: the 27.5 x 2.0 schwalbe g one speed liteskin is, by all appearances, a turd. The cherry on top is that the description on r2-bikes is incorrect and they are in fact tan sidewall.
One was 459 g, the other was 461, not the 400 claimed by Schwalbe. The sidewalls do not feel especially supple; they will stand up against a wall on their own, a feat even the horizon is too supple to achieve:
I will have a ride report in a week or so. But yeah, a bitter disappointment so far on all fronts. I guess they really can’t resist the temptation to turd these tires up with v guard, etc.
Also, r2 charges vat even on exports.

Bastards! Still 20 grams lighter than a standard Compass SBH and wayyy lighter than a Horizon (mine were like 520 iirc).
Let’s see how they ride.
Also r2 bike took vat off in my cart once I made an account with a US address. You sure you got charged?
IME a lot of those places charge vat and then adjust it when it’s shipped.
Oh man, such high hopes.
Every German place I’ve bought from aside from bike-components in like 2009 before they implemented this capability has taken VAT off once I put my address in.
Actually I didn’t get charged vat. It said 0% vat included on the product page and I misread that as vat included, then I saw that the price on my invoice was the same as the product page, and was expecting a deduction as bik24 or starbike do. Still pretty shitty that the product info re sidewall color and the product photo are wrong.
