Aero Sport


Tange Aero Tubing and DecalIntroduced as a compliment to the popular Lotus Super Pro, the Lotus Aero Sport utilizes Tange Aero Dynamics CR-MO D.P.G. tubing, similar to the Super Pro, but features a fully lugged frame instead of the fillet brazing found on the Super Pro.

D.P.G. stands for Double Plain Guage, meaning the sides of the tubing have thicker walls than the curved top and bottom sections.

We believe the Tange Aero Tubing was available before the special lugs had been designed to accomodate the oval shape, this is why many early frame manufacturers using the Aero tubing opted for the more expensive and time consuming fillet brazing process.  Using lugs simplified the brazing process and allowed the frame to be manufactured less expensively.


The CR-MO D.P.G. tubing was probably less expensive to produce than the CR-MO Butted tubing used on the Super Pro. Anecdotal evidence suggests that the Aero Sport cost approximately $800.00 while the Super Pro was $1200.00, offering a great value for a quality aero bicycle.
The Aero Sport used the Shimano 600 AX group of components, very high quality yet less expensive than the Shimano Dura Ace AX group found on the Super Pro. The Super Pro also came equipped with tubular rims and tires, the Aero Sport rode on clincher tires and Araya 700 x 25c Aero clincher rims.

The Aero Sport was only available in two colors, the first models were all "Silver Champagne" and later Lotus added "Oxide Green" as shown on the bicycle below. Both models were originally equipped with "champagne color" Kashimax Aero saddles.

More photos of the Aero Sport can be found in our Lotus Photos and Lotus For Sale pages.
