mine are 42mm on crest rims

apologies, I didn't know you'd fitted them. You must have 'softer' glass down south as up here I've never had as many punctures with any tyres i've fitted

350g

Gravel kings tubeless? Wasn't aware they were tubeless capable

Anyway, 2 Horizons are now in the classified if anyone is keen

Not officially but I've just put 200 miles on mine with no issues, only running 35psi. Thought the 1.75 were 410g?

Oh 42mm, that sound about right.

You need to inflate it at nearly 100psi and leave it over night to stretch the carcass.

Nope, weighed them a few days ago and 350 on the dot. I run them at 35psi too. What sealant and tape combination did you use? Keen to try.

They do seem light but was going off internet wieghts! I just used the Stans tape (I think I used the cheap copy off ebay Tesa 4289), two layers and stans sealant (on crest rims) Went up easy and stayed up after the initial drop over night whilst the sealant sealed around the edges, etc.
Had a puncture last night going home and it sealed itself and still up this morning

650b wheels set with the following features required. Front dyno hub, disk brake, 10 speed, light weight and tubeless ready. What do you recommend 650b people?

MTB rear wheel (like the Shimano centerlock one), and SP Dynamo front laced to similar hubs you can get.

Rims, maybe this;

Or whichever take your fancy.

Front went up after a bit of fiddling. Rear is being a right fucker. Double wrapped stans to no avail. Gonna head scratch and figure it out tomorrow maybe. Neither rim or tyre are tubeless so might be it...but I'll make this goddamned combo work if it kills me. TUBELESS ALL THE THINGS

I would try another layer of tape and soapy water and if that doesn't work find someone with a compressor...my front went up with a track pump but I had to use my compressor on the rear!

Should this be able to take a 650b wheel set?

I think chainstay may be a problem. Currently has pacenti rim and s-one tyres.

are they hourglass chainstays or straight? Seatstay looks fine.

Probably will fit if you cleaned all the cack off

Cleaning who the fuck do you think I am, @andyp ?

You could get lucky with 1.5" (or even 1.75") gravel kings depending on internal rim width but Horizons .. I doubt it.

There are more tyres coming: https://www.bikerumor.com/2017/03/02/fb17-clement-expands-650b-adding-number-new-sizes/

New bike time!

Moots time!

G ones?

Just ordered Stans crest rims and SP dyno front hub / Shimano Deore rear hub for a 650 dyno wheel setup. Hopefully nice and light and easy to setup tubeless.

who has a set of 650b disc wheels that i can try to fit into my commuto x biek?

i am back in London this week and am free most of the day on Wednesday so could travel across town

@amey @edscoble et al?
