    What makes an XC-Mountian bike an XC-Mountian bike?

    On some XC bikes I notice that the frame is much like a road bike. Like my old mountian bike, before there were downhill bikes, it has a almost horizontal top tube with the ground like a road bike. But I love it for riding on the road or XC trails. I guess the other thing would be the tires it comes with (lower profile knobies) and the ~80mm shock.

    But what else makes an XC bike an XC bike?

    xc bike - typically light weight, quick steering, short travel (typically 100 mm or less), has some saddle to bar drop, typically three chainrings, narrower tires (typically around 1.9's to 2.1's), clipless pedals.

    These are just some very generic ideas.

    i just look at the weight and the centre of gravity...XC/AM bikes are usually lighter, can be HT of FS, have 4-5" travel, and the seat is higher than the handlebars

    FR and DH are always heavier, have fewer gears, have 4-8" travel, and the seat is always lower than the handlebars

    just a long way of saying that XC/AM, you peddle, climb, descend. etc...FR/DH are not great climbers and work best with help from gavity

    A lot of all mountain bikes are using air shocks these days, can't really go by that anymore.

    I guess this is a hotly debated topic. I kindof feel that any MTN bike with a horizontal top tube is kinda XC becuase of the geometry closer to a road bike. The large fork on DH bikes really angles the bike backwards.

    But does anyone have any pics of some good XC bikes?

    Differences between my FR rig and my XC rig.

    XC bike has:
    lower handlebars
    narrower handlebars
    longer stem
    shorter fork
    less suspension travel
    lower volume tires
    less massive everything
    longer toptube

    The seat on the big bike can be raised up high for riding to the destination, so that's not really a definitive thing. I also clip into the XC bike and ride platform on the big bike, but that's a personal choice.

    A higher ratio comparing to all-mountain or downhill bikes. Therefore they're faster. I almost have road bike gearing on my xc, it surely didn't come with when I bough it. IMO, that's what makes a true xc bike

    Surprisingly, some dh bikes are ligher than my xc, so the weight is not really an issue... anymore

    xc bikes are never FS for me, only hardtail. The reason being, less pedaling power gets lost on climbs and during sprints
