All The Six Fifty Bees Thread! (650b, 27.5 etc.).

alas 2" gives me only about 2mm of clearance in my stays

I'm not entirely sure if they're specifically the tubeless ones to be honest.

They are these ones.

but the Hetres are taking ages to wear out.

They do don't they? I managed over 10,000km before the tread in the middle starting to go smooth (and increase chances of punctures).

alas 2" gives me only about 2mm of clearance in my stays

I don't know, the 2" mean lower pressure thus likely to have more room.

I have 2.3" on my Arkose, and they rub at 40psi, but once it's at 20psi, it got 2mm clearance.

I speak from experience, I ran 2" for quite a long time at various pressures.

Budget 650b disc wheelset - XLC Evo/DT Swiss 466d - £55

Okay think I'm done with Gravel Kings... Schwalbe G-One Speed the best 650b 1.5" alternative? Shame they don't do them in tan wall. If G-Ones are the only option anyone know the cheapest place online?

Selling some Gravel kings - 27.5 x 1.5 / 38mm . Originals not the tubeless version

Used - front is in good nick with top tread still intact - rear is more worn , top tread flattened with few little cuts etc

Is this too tight for a 650b conversion?
That's the chain stay tyres are 47c wtb horizon

looks fine to me

looks fine to me for posing on the 'gram

Seriously though it won't comply with certain standards but it should be fine, just keep an eye on it. Looks like 42 mm would be ideal.

3 out of the 4 bikes I own have clearance similar to that and it’s not a problem.

Cheers @amey @Heldring @miro_o

The horizons were from a different bike, Would probably better off with a 42c then (or a 44c if it exist)

What is the 650B wheel set of choice if you want Hunt wheels but might not get them in time?

Thru or QR?

Wouldn't recommend this, as the flex will likely to rub on stay.

Current frame is QR but afaik the Hunt wheels would just come with all the adapters so I could migrate them to a another frame in the future. So that would be ideal I guess.

Hi,
I'm thinking about building some 650b rando with rim brakes. The question is - are there any reasonably priced 650b rims with braking surface on the market? Preferably silver.

look what you did @spotter

pacenti brevet, hed ardennes, dont do it

these are quite expensive...I will...
I found Weinmanns Zac-19, anyone knows anything about them? Seem to be fair priced (cheaper than anything else...)

Velocity Atlas (brick lane bikes) or Velo Orange (freshtripe). Still not cheap, but both quality rims.

Good shout, the Atlas are tough as nail rims, but very heavy, still recommended.

The Velo Orange Diagonale hit the sweet spot of weight, strength, width and cost (£60, 550g, 18mm internal).
