Bicycle Saddles and Comfort
How to select a bike saddle (seat) that's not a pain in
the rear.

The most important aspect of a bicycle seat in terms of comfort, is fit.
You wouldn't expect shoes that didn't fit to be comfortable, no matter
how padded or well-made they were. A hard saddle that puts
pressure in the correct places will be much more comfortable than a
mushy saddle that spreads pressure to all the wrong places.
Them
bones, them bones, them sit bones: The most
important aspect of saddle fit is the sit bone (ischial tuberosities - the two
pressure points you feel when sit on something flat and hard) width.
These should be supported by your seat. If your saddle is too
narrow, then the pressure will be on the tissues between the bones
causing numbness and discomfort. If the saddle is too wide, then
it will likely cause chaffing of the thighs, especially at higher pedal
cadences.
BodyGeometry makes saddles in different widths and dealers should
have a device to measure you for their saddles. But, with a little
effort, and the help of a friend, you should be able to measure your sit
bone width yourself. Sit on a hard flat bench and lean forward to
simulate your riding position. Then point out to your friend where
your sit bones touch the bench and let him/her measure the distance
between these points. This distance should correspond
with the distance between the centers of the pads on your bike seat.
Most bikes come off
the shelf with seats designed for average-sized male riders. Yet,
men and women are not created equal in respect to sit bone width (if you
hadn't noticed, then you are spending way too much time on your bike).
Most shops are happy to swap out bike seats when purchasing a bike.
If they aren't, I'd suggest finding another dealer.
Gel Seats:
These seats are more comfortable for short rides, but the extra sliding
and chaffing can cause discomfort on long rides. Also, these
initially feel more comfortable because they distribute pressure from your
sit bones to the tissue around them. This will feel good at first,
but since these tissues include the perineum area, nerves, and blood
vessels which can't handle this for long, the saddle will become very
uncomfortable as the ride length increases. So, if your riding
consists of just a quick cruise around the neighborhood, gels and
extra-padded saddles may be a
good choice.

perineum is the area between the sit bones, through which
traverse the nerves and arteries responsible for regulating
everything from waste to sexual function. See

Saddles: Some saddles have
portions cut out of them to
relieve pressure from your soft tissue areas. This becomes more
important with softer, more padded saddles since you will sink into them
more. Some find this helps, others don't. Have you noticed
the recurring theme here: A good saddle takes pressure off your soft
tissue by supporting your weight on your sit bones.

Noseless saddles: Another popular variation is the
noseless saddle.
These remove pressure from the perineum area. However,
the nose is important for steering and controlling the bike,
especially in mountain biking. But, I should note that
I have a friend who uses a noseless saddle to mountain bike,
and although he's not a hard-core biker, he does just fine.
These can be a good
choice for indoor trainers (see
Indoor Trainers - Beyond
the Boredom) and situations where bike control is not as
important, such as cruising around on neighborhood bike
paths. Here's
another interesting variation
of the noseless saddle. See also

Quick tips for saddle comfort:
- If the saddle is too high, this will cause you to shift your
weight from side to side. This can result in irritation to the
perineal area.
- Tilting the saddle slightly downward in the front will help alleviate
pressure on the soft tissues. However, if the saddle is tilted too
far down, you will place too much weight on your wrists and hands.
The may result is numb hands and pain in the lower back.
- Stand in the saddle occasionally and adjust your riding position
from time to time. This tends to happen automatically with
mountain biking, but you may have to make a conscious effort to do
this when road riding.
- Another tip that some men find helpful is to point the saddle
slightly to the left or right, instead of aligning it directly parallel
with the top tube.

But the final decision should be based on what works for you and the
way you ride. Work with your local bike shop and try a few rides
on different saddles. Also saddles tend to be their most
uncomfortable on stationary trainers
since you tend to stay seated in the same position longer. This
makes trainers good for saddle comfort testing.
