8 Pinion gearbox
A Pinion gearbox is a bottom bracket shifting
system, and can be used with a chain or a
belt drive (not illustrated). The Pinion gearbox
has a twist-grip control fastened to the
handlebars for shifting gears. With a Pinion
gearbox, the chain is tensioned by means of
a chain adjuster (see “Illustr.: Pinion gearbox
with a chain drive”) or sliding fork ends (not
illustrated). For belt tensioning, see the “Belt
drive / Checking the belt tension” chapter.
The Pinion gearbox is an oil-bath gearbox
(see the “Pinion gearbox / Oil change”
chapter). It is not possible to use a coaster
brake with a Pinion gearbox.
