    Specialized Jett Comp 29

    The Specialized Jett Comp is a trail geometry hardtail mountain bike for women. Its M4 alloy frame is specially tuned to get the utmost benefit from the Jett's 29" wheels.

    Specialized compensate for the longer fork that 29" wheels require by speccing a shorter head tube. That way you get the big fork benefits of better leverage yet the handlebars on a 17.5" Jett are no higher than they would be on a 26" wheel 17.5" Specialized hardtail, so you can still carve round corners.

    Specialized also compensate for the longer chainstays that a 29" rear wheel requires by curving the seat tube forward where it meets the bottom bracket. That way, the Jett Comp retains the quick-handling benefits of a tight rear end. These tweaks ensure that the Jett's contact points (the saddle and pedals) will exactly imitate sitting on the same sized 26" wheel Specialized mountain bike.

    Because the Specialized Jet's saddle, bottom bracket and bars exactly replicate their position on a 26" wheeled Specialized MTB, the bike will feel natural and familiar to ride. Then you get the benefits of a 29er. The bottom bracket is lower in relation to the wheel hubs. This drops the bike's centre of gravity so you sit 'more in the bike'. The bike feels more stable on downhills. The big tyres roll over rocks easier and up hills faster. The net result is a hardtail that will help you knock 2 minutes off an hour-long ride round a typical World Cup XC circuit.

    Q. Is the 80mm travel not too little? 
Also, I am confused by what i read on different websites. It appears to me as if the 17" and the 19" have 100mm travel forks. Please can you advise.
    A. All three Jett Comp 29 frame sizes use an 80mm travel fork (the fork offset differs - size 15" has 51mm offset fork, sizes 17" and 19" have standard 46mm offset). The change in offset is to compensate for the 15" frame having a slightly slacker head angle so to keep the handling of the bike similar between all three frame sizes. Having more offset also helps to avoid toe overlap that can be a problem on smaller 29ers. Whether the Jett Comp with 80mm travel is enough travel will depend a lot on the riding you are doing. The effect of having 29" wheels, which roll better over bumps creates the feeling of having more travel and therefore allows for a shorter travel fork to be used. With an 80mm travel fork the Jett is a very capable cross country/ trail hardtail.
