GEARCASES, PEDALS AND BRAKES.
ОглавлениеNearly all the makers are providing sufficient clearance at the crank axle and rear fork-end, so that a gear-case can be used. Many of the makers have gearcases of their own production, and there are two or three detachable ones on the market which are composed of hard and soft rubber, metal and leather combined. More gearcases will probably be sold this year than ever before in the history of the trade, public attention having been largely called to them by the neatness and desirability of the case as used on the bevel-gear cycles.
The average width of tread on this year’s cycles is about 4½ inches.
Pedals are made stronger and larger, and are screwed directly into the end of the crank, the use of the lock-nut on the end of the pedal shaft being almost entirely abandoned.
Brakes of some kind will be more largely used than ever before. External brakes with levers on the handlebars are not as popular as in former years, many of the makers extending the brake stem down through the steering head, thus making a neater and more stylish appearing brake. Brake spoons are mostly fitted with a rubber shoe; and there is a decided tendency toward back-pedaling brakes, many of which are supplied by the cycle makers without extra charge.
Weights run from 23 to 26 pounds, the average weight of roadsters being 24 pounds, and ladies’ wheels averaging in weight about 25 pounds.
