The Planet-X Jack Flash is one of the strongest hardcore/slalom frames ever made. It is made of 7000 series alloy and has 6-yes 6! re-enforcing gusets, box section chian and seat stays, and a chainstay yoke. It has V and disk brake mounts, thith well placed cable routings going to even the disk mounts. The main tubes are double butted for strength at the joints. It even has a replaceable rear mech hanger, should you ever need to relace it. It comes in loads of colours(there are too many to list) such as Green, Orange, Yellow, Red, Black and it even has a choice of two tone colours: black + gold, blue + silver, red + silver and a camoflage paint sceme. The Jack flash isn't light though, so some smaller riders may find it hard to ride with the extra weight. The top tupe only come in two lenghts (22" and 23.5") this is very long and a lot of smaller riders will find it hard to ride.
