Hi I am looking at buying my first road bike, however as i am converting from mtb and all the sizings are different could anybody suggest what size frame is best for me, I am 181cm tall. I keep seeing inside leg measurements being mentioned too im not sure what mine is any idea how or where from and too I measure this from?

Bet this is a common question but any help would be greatly appreciated!

Cheers

Liam

    Probably a 56 or possibly even a 58. Go to a bike shop and try either of those.

    The only way to know for sure is to go to your local shop and try some.

    They vary from make to make[V]

    Hi,

    do a search on - <u>www.bikefitting.com</u> find your nearest LBS that has the equipment, get along there and get measured,(œ35) they will then be able to point you in the direction of bikes that have a geometry that best suits your sizing, as all manufacturers have differing geometry on any given frame i.e. a Specialized bike in a 56 will be different from a Ridley or a Wilier in a 56. Hope this helps. IME the shop will deduct the cost of the measuring service from any subsequent bicycle purchase from them.[8D]

    Lots of recent discusion on this here and in Know How - try a quick search.

    Just for a starting point - inside leg minus 10-11 inches equals seat tube centre to top (virtual if a sloping top tube) seems as good as any.

    A more critical dimension is length. Note the reach from your MTB saddle to bars. If this is a sporty cross-country style of MTB you can use this to set the reach from saddle to the brake levers. If yours is a more sedate leisure MTB then you may want it a little longer.

    Well...none of the C+ guide works for me! Nor does it seem to include reference to vertical difference between saddle and bar tops. If I met standover guide, in order to get saddle/bars near enough level, I'd have to have about 4" of stem/steerer showing.
