I found this on No Pogo and tranlated the french, sorry if its kinda off...... Indeed the Bmtech mark, specialized in the tube of saddle has spring, has just recruited 4 trial riders who will be equipped with the "new system of stem of saddle with variable geometry MB70 model 2004". The system makes it possible to the trialists to roll with a high seat for the long ways and a low seat for the trial. In short a revolution in the world of the trial for only 660 grams; -) The TEAM will be in demo has Toulouse the 06.03.04 and the 13.03.04 in Toulouse with the Workshop of the cycle. :greddy: i hope i didnt make Andrew die with laughter :ugh: *update* so i talked to my friend chip, and weve concluded....... apparently a similar invention has be invented, called a quick release mount, also we figured in a section, you might hear a comment like this... "quick, Francois! Elevate your seat!, you are aboot to land on zee rockzzzzz! raizzzzze your zeeeeat!""
