ebay frame

  • while looking through ebay yesterday i came accross this frame bin £20 so thought what the hell so hit the button now the seller knows nothing about the frame i.e fork size etc 650/700 so how can i work out what is the correct size fork without buying both sizes?

    cheers folks

  • Get the measurements of the frame and go enter it all into BikeCAD and then see how crazy the 700c forks that BikeCAD would give you look on the bike.

    Just a thought... may not work.

  • Ask to borrow a pair of forks from someone? Go into a bike shop and ask?

  • what do you mean with 'correct size fork'? if it's 1"1/8 or 1"? I'm lost..

  • never thought of 1" or 1"1/8 wanted to know what blade lenght

  • I think the dent on the down tube would be my first concern

  • i can remove that easy enough i work with custom cars and paintless dent removal is one of my jobs its really easy with the right tools of the trade even if i have to tig it(also coded welder) its no biggy

  • its a road frame, it'll be 700c.

    it looks to be a road frame tried bikecad cant get it work

    Not sure that's quite how it works. The headtube looks quite small (even when you take into account the oversized down tube).

    Maybe the whole bike takes 650s

  • measurments top tube 490mm seattube 480mm downtube 580
    lower chainstay 400 upper chainstay 450 if it helps?

  • Not really. Best to take it into a bike shop and ask to try a set of wheels on it.

    Thats just over (by like a cm) the dimensions when 650 wheels become popular. I'd still guess at 700c though.

    The axle to rim distance on a 700c rim is 622/2.
    So assuming 45mm reach for brakes (39 - 49mm is standard for a road bike), you'd have a distance from axle to brake mount of around 356mm. Try mearsuring this to see.

  • Also on such a small frame the head tube angle is likely to be slack. So you might need a fork with a large offset, to obtain a nice trail for road riding.

    Its stuff like this that make it fun :)

    But, as well as having the guesstimate the best fork rake, there is another problem. That looks like a integrated headset frame. So you will need to take the calipers to it, to work out exactly what headset you need.

  • it's horrible, horrible. just don't, don't.

  • i think it is an integrated h/set but i have a few in my parts bin anyway

    I meant that there are several different sizes of integrated headset.

  • cheers for that it's gonna come in handy

    Sounds like you're mechanically minded (going by job), so if you can get hold of some calipers, it should'nt be hard too work out which size to go for.

  • could easily be 650c like a GT vengeance

    soon as it gets here i'll measure up shame im off to turkey tomorrow for 19 days so even when it gets here i cant play

  • Looks like a road version of a Montana Track.
