700cc wheel on frame for 27" brakes

    Is the problem with brakes unavoidable or is it just a matter how much one can move the pad up and down?
    I have an old falcon I am in the process of converting. While it needs 27" wheels, the 700cc seem to be the future and could be more versatile once I change the frame.
    I suppose riding brakeless with no previous experience on fixed is not a good idea? :)

  • you'll just need some long drop brakes. easily available. perhaps a little drilling might be needed to but that's no big deal.

  • I've got 700c wheels on an old MBK frame that was meant for 27', it's no problem, as said above, just get some brakes with a longer bit for the brake pads and hey presto.

  • Thanks Guys.
    I read somewhere that the difference between 27 and 700 is roughly 5mm in diameter.
    Is that true?

  • 27 1 1/4 rims are not only larger diameter, but the actual rim width is wider than most 700c rims that you might find.

    Also the tires you get for 27 wheels have more diameter,

    all that together makes 27 inch wheels feel very different to 700c with popular 23c tyres, the end diameter including tyres height is a fair bit more.

  • Yeah, what skeleton boy said... I've got 1 1/4" tyres on my Mercian road/path (check my gallery pic), very different ride to 700x23... Feels like a monster truck wearing moon boots in comparison... Tough to get decent puncture-proof tyres for 27" that are anything smaller, not impossible tho'... I've got two 27" frames so decided to go all out and build a 27" wheelset, clearance is still massive on the track frame even tho' it's a proper old British track frame... Still needs a long drop caliper... There are loads of suitable ones to be had, been talked about loads on here, get an old Weinmann or a lush 70s Dura-Ace like PJ's which, by the way, I must have...
    Brakeless is for the reckless, but that's another (more tedious) conversation... Anyway, I'm rambling... Yadda, yadda, yadda...

    I roll on a continental Ultra Sport Gatorskin/duraskin K+ or something!
    (thats what you call "name wanking" )

    Apparantly puncture proof, available in 27 1 1.4

    although not thin, they feel awesome, tons of grip, roll fast, take loads of pressure, around £17

  • You can get Gatorskins 27 x 1 1/4

    My geared bike might be slipping a pair on soon.

  • i have as spare pair of bontrager hardcase 27 1 1/4 if you want. this is because i found some panaracers in 27" with a one inch carcass, so much nearer to 23mm than the old 1+1/4s.

    as teenslain said, i'm running a 70s dura ace. works fine with 700s. it's a lovely looking brake too, with a QR.

    these are the brakes i have:

    pretty much original, i.e first edition DA calipers. cost 11 quid or something off the bay for the pair. seriously, the past two sets of weinmann 500s i got - which are good stoppers and look good, cost about £3 each. i also have some GB coureurs, they have a mega long drop. you could run a 26" wheel on a frame built for 27s and the brake would still work. (i know this for a FACT).

    Little known fact: NOS Gatorskin 27s are still out there in 1" (if you look hard enough)... I'm hoping to bag some this weekend... I'll let you know if I can bag a few pairs... i've decided 1 1/4" is too big for my taste...

  • 1 and 1/4 is shitty.

    it's like riding your mum's hybrid. or like riding your hybrid mum. i can't remember which.

  • your mums hybrid measured more than 1 &1/4 last time i looked

    classy, joe. you got class.

  • I used to ride my Dirt Jump mtb thing with 2.2-2.4 tyres on it as a street bike. It feels a bit silly jumping back on it now, but Ive ridden up to 12miles on it with slammed seat and all...

  • As bb is lower, best to get shorter cranks as well.

    That's a very good point if someone is going fixed.
