CLEVELAND
TANDEM.

The tires used on tandems differ somewhat from the ordinary tires in use, being somewhat thicker and heavier, and are usually stamped “Tandem” where they are branded. The average size in use is about 1¾ inches, but some of the makers furnish them as large as 2 inches. The dropped crank-hanger fad does not prevail to so large an extent in tandem construction as in the single construction. Sizes of tubing used show a slight increase in diameter over that used in making single bicycles. The majority of brakes fitted on tandems are of the lever and spoon pattern, working on the front tire. Hubs, rims and spokes are made heavier, and the three-plate crown seems to be a popular one among the makers who use the double-plate crown on their singles. The Adlake has a quadruple-arch fork crown.

On the World tandems and multicycles the crank-hangers are hung in a swinging bracket, which are held in place and adjusted forward or backward by a set screw having lock-nuts to hold it in place, and which is connected back of the hangers to the lower main tube of the frame.

On the Geneva tandem the front bracket is a special device of theirs which consists of a tubular bearing barrel sliding in an oblong hanger fastened with set screws in front, with caps over the ends secured to hanger with lock-nut.

The Demorest tandem has the rear seat and pedals very much higher than the front seat, so that the rear rider can look over the head of the front rider. It appears to be a revival of a similar type that was made last year by the Crescent people, although it is not carried to such an extreme height as it was on the Crescent. Wheel-bases run from 65½ to 75 inches, the average wheel-base being about 69 inches. Weights run from 40 to 50 pounds, the average being about 44½ pounds.
