Самый легкий велосипед в мире
Günter Mai from Lampertheim has modified virtually every part on the bike, including the set of custom Lew Racing Pro VT-1 wheels. Off the shelf VT-1 wheels weigh 850 grams a pair and are made for use by riders up to 185 pounds. They sell for about $6000, while custom wheels like Mai’s cost $15,000.
Mai’s wheels were designed around Mai’s 150-pound body and were delivered to him weighing 734 grams (1.6 pounds). Mai took off another 30 grams by shaving material off the axle end caps, replacing the steel freehub pawls and hub spacers with titanium versions, using tapered carbon/boron axles and full ceramic bearings. He also carved off some of the freehub splines that are not needed with the six-speed cassette he uses.
Известны лишь общие параметры: вес велосипеда 3.3 килограмма, вес рамы 677 грамм, модернизированный задний переключатель 51 грамм. Переключение, как видно на фотографии, на раме, количество звезд на кассете минимально.
