Bicycling 101 - Clipless Pedals
by Liz Sands
One of the best upgrades that beginning cyclists can make is to acquire clipless
pedals. First, some terminology. A plain pedal with nothing to keep your foot
attached is a platform pedal. If you add a plastic cage to the pedal that
goes around your foot, with a strap that can be tightened, then you’re talking
about ‘toe clips’. Pedals that have some form of mechanical connection with
your bike shoe, usually a cleat on the bike shoe that locks into a receptacle
on the pedal, are ‘clipless pedals’ (clipless because they don’t have ‘toe
clips’).
Why make this upgrade? Your pedal stroke is much more effective when your
foot is attached to the pedal and can exert force through a greater range
of the pedaling circle (with a platform pedal you can only exert force on
the downstroke part of the circle). Toe clips do offer some of this efficiency,
but they can be difficult to get in and out of when starting and stopping.
In order for toe clips to be the most effective, the strap should be tightened
after you get your foot in - you then need to remember to loosen the strap
to let your foot out when you need to stop.
In contrast, most clipless pedals allow you to step on the pedal and immediately
‘click in’ instead of fumbling around with getting your foot into the toe
clip cage. To release from the pedal, usually all that is required is a twist
of the foot.
There are lots of different clipless pedal systems out on the market. If
I had to recommend one particular kind to a beginner, it would be an SPD-style
pedal and cleat. With an SPD-style cleat, you can choose to buy a shoe where
the cleat is recessed on the sole. This allows you to walk around more easily
when you’re off the bike, unlike the larger cleats that make us walk like
a duck when we go into the convenience store to buy Gatorade. The other advantage
is that most SPD-style pedals have a tension adjustment that allows you to
make the pedal-cleat connection looser or tighter. That’s a big plus when
you’re first learning how to use the pedals – you can adjust them to be loose,
so that you’ll be able to twist your foot out of the pedal quite easily.
When you’re shopping for clipless pedals, be sure to ask whether the model
you’re looking at has tension adjustment. Another thing to keep in mind when
you’re shopping, if you already have bike shoes, is to buy a pedal whose cleat
can be installed on the shoes you already have. If you’re shopping for both
pedals and shoes, again, be sure that the pedals and shoes you buy are compatible
with each other.
Another feature to be aware of is how much “float” a particular pedal system
has. “Float” is how much the pedal will allow you to wiggle your foot around
on the pedal. People who have knee issues are going to have to pay more attention
to float (some peoples’ knees feel better with more float, and some do better
having their foot in more of a fixed position). It is very important to have
a knowledgable person at the bike shop help you with the placement of the
cleats on your bike shoes. You want the cleats to be positioned so that your
knees end up in proper alignment.
Down the line, more advanced cyclists often will move on to different pedal
systems than the SPD style. These cyclists are looking for features like lighter
weight pedals, more cornering clearance (pedals are shaped so that you are
less likely to hit a pedal on the pavement when leaning the bike over in a
corner), and an extra secure attachment so that they don’t pull their feet
out of the pedals during a sprint. There are many different options and like
other types of gear purchases, my advice would be to start by talking to other
members of the club and finding out what they like and don’t like about their
particular pedal system.
