the front rim to match. The pair were
practically perfect at the end OF the sea-

another years use. 1t is to be remarked
that the two vanished rims gave out in
less than half the time the wheel was
used. so it cannot be well denied that there
was merit in the application of the enamel.
Apropos of rims and tires. about Is per
cent. of the wheels sent out for use are
fitted with tires which are poorly ce-

look 10 the fitting of his own tires on each
machine for which his tires are bought.

good old-fashioned cement was used. but
bicycle manufacturers are in a hurry to
get their product in the hands of the con-

A word or two about cementing tires

suits. the rim must be cleaned on that part
