    Exceptionally dull I know, but anyone got any ideas? Looking for 700C/622/'normal road bike' size, width as much as possible (25mm+), 32 spoke, braking surface.

    Best I can Google is a 'Velocity Dyad' at 24mm, but can't find any UK stock.

    Comedy Surly sizes won't work as it's for a rear wheel, and the fatter unicycle rims either have no brake track or are 36+ spokes. Definitely options for the front though.

    The observant will spot the MonkeyCross concept slowly morphing into a slightly-fat-bike-on-the-cheap...

    Wider than something like a Mavic A319 or A719 touring rim? I think those come in 32h flavour and will take tyre up to 38mm (at least that's the fattest I've had on them). A319 is about £20-30 and the A719 about £40-45.

    n00b question: does that mean what MTB types call 29" is actually 700c?

    Yup. 700C/622/29" is all the same thing. Wonderful, eh?

    The issue is that most of the wide 29er rims assume you're using disc brakes, and I want canti's because a) I want to be special, 2) I've already ordered a flip/flop hub and iii) I don't need the power of a disc on the rear wheel.

    I use those Mavics with cantis on a tourer.

    And yup, I'm concerned I'm going to end up with something like the A719, but I really wanted to go with a rear tyre that's about 55mm width which isn't going to work on that.

    Part of this is On-One are selling the fantastically-named Rubber Queen at £15 at the moment...

    Ah. 55mm. That's big.

    As long as you don't go crazy with your track pump, you can probably squeeze a 55mm tyre onto a A719. I'm currently running a 54-559 Ice Spiker on a Mavic XC717 disc rim, at about 50psi.

    I'm effectively trying to build this on the cheap:

    "does that mean what MTB types call 29" is actually 700c?"

    Yes (as answered above) - of course whether it is 29" - or 26" on 'normal' MTBs - depends on the tyres!

    And now, the new trendy size is going to be(???) 650B - aka 27 1/2".

    More than you ever need to know -

    Go full Frankenbike and have a skinnier real wheel?

    There might even be a real argument for that in a city fat bike. My gut says that since braking force puts weight onto the front wheel and off the back, the benefit of a big bouncy tyre is smaller for the rear.

    Uberuce, Joe Murray was doing that with Kona mountain bikes in 1990. Not so much for braking forces as shock absorption and greater control, while saving a bit of weight on the rear tyre.

    Had a look at rosebikes.co.uk?
    Beware the final stages of their delivery process, which seem to unavoidably involve Parcelforce.

    I was almost very excited, but it appears they're measuring outside rim width rather than inside (I checked their quoted size for the mavics). Thanks anyway!

    It was always going to be a bit frankenbike, as I want something really large on the front for the shock absorption Arellcat mentioned.
