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

you want to buy some tasty 650b rim brake wheels? ;)

But IMO if its a steel frame just get some V brake bosses brazed on for 650b and use with mini V brakes and drop bar levers for the best braking performance.

I won't be buying any time soon but thanks! I'm more thinking out loud for when I eventually graduate and have some ££. Steel track frame and carbon fork which fits 28mm front and back, I'm thinking it should be a good candidate.

The whole thing could end up being fairly cheap!

Those brakes are terrible and whats the point of going 650b mere 35mm tyre? At least 48mm.

Get V bosses brazed on, it'll be cheap. Use V/Mini V brakes.

I hadn't realised 650b+48mm is only 2mm bigger than 700c+28, thats pretty exciting.

Is there a good rim brake option? A more expensive idea could be a disk fork but I wouldn't imagine a 1" steerer road disk fork is something that actually exists
It's fixed so the brake just has to be good enough, nothing stellar

carbon fork

A ratty old steel fork would be an option I guess

VO Diagonale is good. I think there is one that Velocity makes as well.

GET V BRAKES BOSSES BRAZE ON. Its the cheapest/best solution.

The brakes you listed are great, not terrible in the slightest.

I and the girlfriend have exactly that, with new pads and decent housimg, they stop great.

Nah they're shit. You know my braking standard.

Cheapest solution is getting long reach brakes, the whole point of the conversion is to be able to use existing frames without modification

Well my calculation is based on Winston's charges for brazing those bosses on plus some cheap tektro V/Mini V.

What are these tasty wheels?

VO Diagonale on shimano 5800 compass GB tyres all silver

Ah, I need a 135mm rear hub. Sound shiny though

I use it in a 135mm frame, no issues.

Shimano R650 is also pretty good.

wont work

Ah yes, probably not long enough drop - I forgot it was only 57mm. @alialias, V's make most sense as @amey says - they'll fit around the nice big tyres. I've got TRP CX9s and they work a treat. The 90mm arms give you quite a bit of space.

Absolutely. I use CX 8.4 on my daily bike and they are awesome.

What inner tubes are people running? I'm finding it hard to get good quality tubes for 650 x 42mm

Sv12

Not long enough I'm afraid, but the best is usually the Tektro R559 which is more than enough to stop you and have clearance for 42mm tyres.

Just get 26" inner tube, it's like buying the 700c road inner tube for 27" wheels.

Didnt know about that.

Good spot @amey might consider those for the daily bike...
