A "TURBO" low-profile track frame made by MECACYCLE of St Etienne in the mid-80s. The main feature of the "TURBO" frame was the use of twin aero section fork blades used to replace the seat tube, enabling the rear wheel to pass between them, thereby producing a rear triangle of 37.5cms.. Various tube sets were available and the frame could be built for road track or time-trialling in low-profile or standard design. Early models had the tips of the blades bronze-welded to the bracket shell, but later ones used a special cast bracket with sleeves to receive the blades.
First introduced in 1983 as a "Bernard Thevenet" branded CIZERON, the model emerged a year or so later in the colours of Cycles Delcroix of St Amand les Eaux near Valanciennes in northern France.

In the 80's the pro-sprinter Jelle Nijdam (Buckler, Word Perfect)was also riding a two tube bike. These tubes were the bottom tubes from the bracket to the steeringtube. They also gave him a smaller frame and lengenth the seet tube with an extra 10 cm.
ReplyDeleteHi, the red bike in the first picture isn't a Mécacycle but a Solender (another French builder who used split tubes). ;)
