Rollers – A system of usually three parallel cylinders (rollers) that the bike sits on and which spin as the wheel are turned. Typically the rear rollers will be attached by a drive system to the front meaning that the front roller and therefore wheel will be
turning at the same rate as the back one. Bike rollers provide
for development of smooth technique and balance and are
favoured by track cyclists because of this. We can all benefit
from refining our spinning technique and balance –
smoother riding means more efficiency and the ability to go
harder longer.

I know what your thinking ‘How the hell do I balance when I
have no forward momentum?’ A coaches standard reponse will be
‘Just don’t think about it too much.’ You’ll find the same
forces are at work when on rollers as are in play when you’re
on the road and this is a great way to improve your form.
Rollers are more about technique than fitness although with
some models you can attach a mag resistance unit.
