There is a distinct reversion toward square-section cranks. In crank-axles, the one-piece type has evidently come to stay, and it is followed closely in popularity by the two-piece crank and axle. Very few of the makers use the three-piece construction, and even in these there are peculiar and odd forms of fastening the crank to the axle, the use of the good old cotter pin being nearly abandoned. This may be accounted for mostly because the makers desired “something different,” and also on the ground of neatness. The main objection, however, to the use of these various types of crank fastenings is their entire lack of interchangeability, so that the rider who has one of them and breaks or loses a part of his crank fastening, cannot obtain this part or any repair thereto, except through the maker or dealer who handles this particular pattern of wheel. Under the old system of using the cotter pin the cranks and cotter pins were readily interchangeable, and therefore this tendency to variations in these parts is to be regretted.
