  • Not sure about your inside leg guide. Its one of the odder pieces of advice given on this site .

    May I suggest the following?

    I have an 81" inside leg, which I measure from crotch bone to heel. Your saddle height, measured from the centre of the bottom bracket axle to the top of the saddle, should be that measurement less 10cm , give or take a few mm.

    That give me a 54cm frame ( C to C ) for racing and a 56cm ( C to C ) for Touring.My saddle height is 70.5 ish

    As important as frame size, measured as the seat tube , is the top tube length . This is ought to be the same as the saddle tube and a bit more for a tourer.

  • yeh exactly my thoughts, how about wheels? ;) those phil wood, mavic open pros look lush £300 good deal?

    They are nice but I think £200 for the rest is spreading it a little thin - you wouldn't want superbling Phils on a crapper of a frame?

  • yeh exactly my thoughts, how about wheels? ;) those phil wood, mavic open pros look lush £300 good deal?

    These wheels are pretty much bomb proof and will look good on almost any ride - thing is you can buy a brand new set of wheels at hubjub for just about the same price http://www.hubjub.co.uk/philwood/wheelshf.htm although that won't include shipping - so you are saving about fifty quid - certainly you can buy wheels cheaper than this - but I have a set of these wheels from hubjub and four years later they are as straight as a die - my mind is that wheels are worth spendng money one

  • Peter Carter's going wild, mixing metric and imperial.

    Its okay though...hes a giant

  • rocker9455, have you never had your own money with which you had to budget and choose what you should and shouldnt buy and how much you should spend on each thing for the amount you have?

    break down your costs and then work out how much you can spend on parts depending on how much you have. Otherwise your just asking silly questions.

    If not, your probably better off asking your mother to get behind the keyboard for you and we can speak to her...

  • lol course i have had a budget before! anyway i said i've taken it up to £800, and im thinking £300 is probably a fairly good price to spend on weels

  • In that case have a look at the Gorilla frames at hubjub - Will at hubjub is a sound sound fella

  • Infact Will still has a 54 cm Bareknuckle going - that and them wheels - you got yourself a blindin little bike

  • lol! i really want an old track bike plus im slowly building up those funds :D for wheels il prpbably go with hubjub ones unless the others drop to a significantly cheaper price i would rather pay £20 for a new pair! i think i will just trawl through the ebay finds and for sale looking for a frame until i find one, i think il go for a 54/55cm frame

  • just got the price for the wheels down at £300 with tyres, worth it or not? im still leaning towards hubjubs at the moment

  • very nice fream, I have seen it in real and is nice

  • its a little too big for me but i still have a few years to grow into it ;) i might go for it, hate that fork though!

  • how old are you?

  • different style of frames

  • different style of frames

    how do you mean different?

  • I would say a 55cm (C-C) frame.
    But maths is a pretty bad tool when bike sizing. I'd try and have a go on a 54, 55, or 56 and get an idea from there. The most important factor is top tube lengh, which *might *be relatively short if you pick a track frame due to the steepness of the seat tube.

    0.883 x inside leg (with bike shoes) = distance from BB to saddle top
    *0.883 x 33 = 29.14*

    Therefore...

    Saddle height (2.5 inches?) + seatpost height (5 inches?) + seat tube lengh (frame size) = 29.14
    *29.14 - 2.5 - 5 = Frame size = 21,5" (55cm)*

  • Top of saddle to pedal ( crank in line with seat tube) = 1.09 x inside leg (without shoes)
    Works for me (and many others) as a good starting point.

    this is a beauty

    I'd expect that to fetch a handsome sum. Beautiful frame, nicely restored, with lovely nervex lugs. Seems to have really long track ends, but maybe thats just me. Its a bit big at 58 (C-T)

  • Top of saddle to pedal ( crank in line with seat tube) = 1.09 x inside leg (without shoes)

    Interesting, not used that one before. Gives a frame size up from my earlier caculation. Thats assuming short (165mm) cranks though.

    33 x 1.09 = 36

    *36 - 2.5(saddle height) - 5(seatpost) - 6.5(165mm crank) = 22.0 frame size (c-c) (56cm)*

  • cool thanks for the help guys, give me a shout if anyones selling 'vintage' track frames!

  • BTW you should properly measure your inside leg before deciding on frame size, as opposed to just relying on jean size :)
    Stand with heels against a wall and place a book (or similar) between your legs, pressed up to your crotch. Measure from the top of the book to the floor (tends to be a bit longer than ideal trouser size)

  • re measured my inside leg its 35"
