The art of smooth pedalling
Using a fixed gear bike to improve smoothness in your pedal stroke.
Use of a fixed gear bike will focus you on your pedaling technique as well as increasing leg
speed and strength. The mechanics of a fixed-gear bike require you to pedal as long as the
bike is moving forward. Inexperienced riders should consider using a fixed-gear bike on a
stationary trainer for the first couple of rides.
Pedaling continuously will develop a smooth pedal stroke as you spin down hills and
increases leg strength as you climb the hills. Generally, gearing for a fixed-gear
bike will be light (42x19, or about 60 gear inches), which is a nice balance for
various types of terrain.
You might consider using an old road bike, adding a fixed-gear rear wheel from a used
bike shop. Unthread your chain from the rear derailleur, shorten it, and place it around
the small chainring in front and the single rear cog, and you're done. You can also use
a track bike for this purpose. You will need to install at least one brake before you go
out on the road.
One-Leg Pedaling
One-leg pedaling is another approach to adding strength (and variety to your indoor
training at the same time). Normally, when you pedal with both legs, the leg that pulls
the foot through the bottom of the stroke and back up to the top of the 360 degree "cycle"
is under used (as the other leg, when pushing the crank through the downstroke has
significantly more power and thus allows a bit of slacking).
Learning to pedal a complete, 360-degree circle with both legs working together
will make you a better rider. Practicing with one legged drills will embed this
idea into your pedaling style.
Warm up on the trainer for 20 minutes while pedaling with both legs.
Unclip one foot from the pedal. Rest it on a chair or stool just outside the left pedal circle.
Pedal at 90 rpm using your right leg, using an easy gear until you get accustomed to the feeling
of one-leg pedaling. The muscles that lift your thigh and push the pedal over the top will
fatigue quickly at first, but you'll improve rapidly.
After a few minutes, switch to the other leg.
Cadence
If you're relatively new to cycling, you are probably riding at a cadence that
is below your optimum. Most new riders think they are getting a better workout if every
pedal stoke is a strain and the quads are burning. Although there's a place for low-cadence
workouts, during a normal aim for a smooth spin at between 85-100 rpm (pedal revolutions
per minute) which is much more efficient -- and easier on the legs, especially the knees.
Lance Armstrong has popularized high-cadence pedaling. He spins at about 90 rpm on even
the steepest climbs, and he's regularly over 100 rpm in time trials. Does this mean you
should be pedaling at a high cadence as well? Although your cadence can be increased
through training, it may not fit with your personal physiology and biomechanics.
Try this to see what cadence may be the best target for you.
Locate a protected 2-mile stretch of road (without significant cross streets or traffic).
Ideally slightly rolling.
After you warm up for 15 minutes, ride the route hard in your biggest gear. Note your finish
time and your heart rate if you have a monitor.
Recover for 15 to 20 minutes with easy spinning.
Ride the course again at the same heart rate (or perceived exertion if you don't have a monitor).
But this time choose a rear cog that's one or two steps larger and allows you to keep your
cadence about 100 rpm. Note your time for the same course.
After a day or two of rest, do the test in reverse - larger rear cog (lower gear ratio) first.
Compare your times. For most riders, the lower gear and higher cadence will produce faster
times for less perceived effort.
Here are two drills that may be helpful in increasing your cadence and maintaining the smooth
spin of a veteran.
Use a down hill to practice. Spin in a small gear on a slight descent, then gradually increase
your cadence until your pelvis begins bouncing on the saddle. Back off about 5 rpm so
(the bouncing stops). Hold that cadence and concentrate on a smooth pedal stroke for one minute.
Cruise back up the hill and do it again. Relaxation is the key to pedaling at a high cadence
without bouncing. Keep your elbows, shoulders and hips loose.
Use a that tailwind that you have stumbled across. Shift into a moderate gear and gradually
increase your cadence until you're at 100-110 rpm. Hold it there for 30 seconds, then gradually
ease back to 80 rpm. Repeat several times.
How do you estimate your cadence if you don't have a cadence fundtion on your computer? Set your
computer display oto show seconds show. Using your right foot, count how many times it is at the
bottom of the stroke during a 15 (or 30) second interval. Then then multiply by 4 (or 2). That
will help you develop a sense of what 90-100 rpm feels like.
Shifting
The secret to smooth shifting, especially on hills, lies in planning. Anticipate you'll
need an easier gear and shift a few seconds ahead of time - including shifting to an
easier gear at the bottom of the hill while you still have momentum.
Just as you move the lever, ease up pedal pressure. The shift will occur during one crank
revolution. If you time it right, you won't lose significant speed. And if you are worried,
push a bit harder for several strokes before lightening the pressure on the shift stroke.
Bottom line: Any time you shift either derailleur, be conscious of your pedal pressure.
Shifts made during a moderate application of power have the best chance of being smooth and quick.
Paceline Training
Paceline Skills. A great way to improve paceline skills while limiting risks.
"With a few friends, find a hill several hundred yards long. It doesn't have to
be steep. Ride up in a paceline. Work on pedaling smoothly and maintaining 12-18 >
inches between bikes. Here's the key to this drill: Keep the speed low.
Around 5-7 mph is perfect. Everyone should be pedaling with the same cadence.
No one should be struggling to keep the pace. Low speed ingrains smooth technique.
In a normal paceline, if you speed up, you quickly overrun the next wheel. If you
let a gap open, it takes effort to close and this messes up riders behind.
But at slow speed on a gradual hill, there's less penalty for mistakes -- and you can
simply put a foot down if you make one. Trade the front position after short pulls.
Just 20-30 minutes of this slow-motion drill will make you and your friends noticeably
better when you're in a paceline that's traveling 3 times faster."
And a second article, same e-zine (roadbikerider.com):
"Catch a draft! The best way to learn good drafting technique is to pair up with
an experienced rider. So if you're an old hand, help a new rider learn. If you're a newbie,
find a grizzled vet who's willing to help. In this example, we'll assume you're the rookie.
Ride at a moderate pace on a low-traffic road. Put your front wheel about 3 feet behind your
guru's rear wheel. As you feel comfortable and confident, get a bit closer -- maybe 2 feet,
then 18 inches. Notice how the draft is stronger when you're closer to your partner's wheel, weaker as you
drift back. Notice how you feel more draft when speed increases.
Feel how the draft moves slightly to the side in a crosswind. Protection increases to the
right of your partner's wheel when the wind is from the left, and vice versa.
Good drafting depends on smooth, even pedaling. If you pedal and coast, pedal and coast,
you'll find yourself getting too close to your partner or too far back. Keep the crank
turning and use slightly more or less pedaling force to maintain a constant gap.
Now practice rotating the lead. The front rider checks over her shoulder for traffic, drifts a couple of feet to one side
(determined by wind direction, road conditions or traffic) and slows slightly by soft-pedaling.
You take the lead not by accelerating but by keeping your speed constant as your partner
slows. Pedaling will feel a bit harder because you're bucking the wind. Glance at your
cyclecomputer to make sure your speed stays steady.
Stay close as you pass each other while rotating the lead. The closer your shoulders are,
the less wind each of you will be pushing and the narrower your combined width.
That's important so motorists can deal safely with your presence.
When you're the person dropping back, begin accelerating slightly when your front
wheel is beside your partner's rear wheel. Then you can slip in behind before
a gap opens."

Cornering
The secret here is to keep your momentum during turns. Novice riders will waste
their momentum when cornering, while the more experienced will sweep through the
curve and open a gap that costs others precious energy to close. Corner after corner,
this efficiency really adds up.
Here are a few tips:
Shift down before the turn. If the corner is tight (which will naturally make you slow),
shift into a lower gear before you enter the corner, stop pedaling, and start leaning the
bike. If you are in too large a gear, it will take more time to get back your momentum.
Practice standing versus sitting when exiting the curve. Cornering soaks up your speed,
so you may choose to stand and sprint to regain momentum. However, standing uses more
energy so in wide, sweeping corners you may opt to stay seated, and work a little harder
to keep contact with the group (especially in a downhill turn). There are additional benefits
of standing out of corners.
You use body weight to power the pedals and the tendency to shift to a lower gear.
Standing avoids the temptation to use more forceful pedal strokes in the saddle and increase
knee strain.
Standing relieves saddle pressure - and even a few seconds will add up to decrease discomfort
over the ride.
Standing will stretch your legs - and back. This will combat the stiffness that occurs with
long rides.
If you get in the habit of standing for a few strokes after most turns, even if it isn't
necessary to stay with the group, you'll ride more comfortably.
Be prepared to sprint. Be ready to invest a sudden burst of energy after each turn.
But if you can stay seated, and still stay with the bunch, it will save you energy to
use on that final sprint at the end of the day or in the hillier sections.
