Hi there, I have a

23" Giant Yukon (08)

and a

23" Townsend Terminator

The Giant is MILES bigger than the Townsend when sat next to each other and the Townsend feels way too small for me, Now this isnt much of an issue as it just gets used for shopping etc but im looking for another commuter and was just wondering if The Giants are bigger (hence the name) or if these days they are all the same but the Townsend is just smaller because it sooooooo old ?

Hope that makes sence ?

    all bikes have different Geo.

    also different companies measure frames differently.

    Thanks Typically what frames would be bigger ? If I am looking to buy one from far away (ebay etc) would makes should I be looking for to the same size as my Yukon ?

    For instance would a 22" Kona be the same, Or a 25" Dawes etc, Im sure im probs asking an imposable question, Sorry

  • like nick said different manufacturers measure frames differently

    Suppose the best chance of getting a bike to fit would be to stick with same maker. Even then other dimensions come into play ie top tube length

    Giant XTCs have long top tubes for a stretched out racer position

    their trail bikes are totally different

    If you want some kind of answer to your question get yourself round some dealers and compare different brands

    bike sizes really mean nothing except that say a 18" Yukon is smaller than a 23" Yukon.

    even two different frames by the same maker given the same "size" often are different.

    its impossible to say, but heres an example of how some bikes are measured.


    i recently bought a 17" frame full susser. thats from the BB to the where seattube meets the toptube. but there is another inch of frame on top of that for the seatpost. this really makes the frame 18"

    another bike by the same manufacturer says its a 17" frame but only has about 1/2" for the seatpost.

    some builders measure from the bb shell to the bottom of where the top tube joins , some to the middle and others to the top. this can be a problem with oversize tubing, as much as an inch in difference. some count the seatpost mount and others dont.

    the only way to be sure is to try a few different frames and see what suits you best.

    My Specialized Pitch (made by Giant) is 19in centre of BB to top of seat tube but about 13in from centre of BB to top of top tube. However the top tube length of the 19in Pitch is about the same as a 19in Gary Fisher Genesis geometry bike or a 20in Giant Reign.
