does come in other colours but this green is the closest in SHORE hardness to the originals , the originals were 70 , these are 80
there are other COLOURS available , but are too hard , and will cost you £45 for the length , bit expensive for colour coding
the only difference is in the materials used , these are UV resistant
which was the main cause of the originals deteriorating
jez , if you undo the large silver cap at the top of the rear stack , you will find that the elastomer is actually two pieces , seperated by the black spacer , a bit like the spacers in a manitou fork , helps with the travel
the microwave trick will work but they will soon go rock hard again in a day or two
