Burley Tandem Suppplement
On tandems with a sloping top tube, you have another reason to buy small. The
sloping top tube increases the effective size of the frame, because the head tube is
higher than the seat lug where the frame size is measured.

The Stoker
Size matters less for the stoker. The stoker has two concerns: seat position and hand
po si tion. Because the stoker can mount and dismount as you would mount and
dismount a horse or motorcycle (while the captain holds the bike upright), straddle
clearance is much less critical. So if need be, the stoker's seat can be low, close to the
top tube. At the other extreme, the stoker's seat can go as high as long seatposts
want to place it. If you are planning to spend a lot of your time off-road, the stoker
should prob a bly have standover clearance ad e quate for an emergency bailout.
The stoker's hand position is determined by the stoker stem and han dle bars.
Assuming that the captain's seat is not bottomed out, it is no problem to move the
handlebars up or down. The adjustable stoker stem offers a number of inches of
fore-aft adjustment for the stoker's handlebars. On a single bike, adjusting an off size
frame in this way would screw up the fore-aft weight distribution and and result in
sub-standard handling. This is not the case on the rear of a tandem. If you can get the
seat-to-crank-spindle distance that fi ts your body, the other factors will fall into place.

III. Starting Up
The Captain
Shift the tandem into a suitably easy gear. Now straddle the top tube. Next, grab the
handlebars, lock both brakes, and place both feet fi rmly on the ground, straddling
the top tube. Keep your legs spread wide, so the pedals can move around between
them. The bike is now held securely in an upright position. Invite the stoker to climb
on board.

The Stoker
The easiest way is for the stoker to stand on one side of the bike and position a foot
on the near pedal. He/she can then use that pedal as a step and gently swing the
other leg over the seat, as if mounting the back of a motorcycle. If the stoker is not
comfortable with this approach have the stoker step over the top tube with one foot
on the ground (as he/she would on a single bike.) Once both feet are clipped in, the
stoker can backpedal to get situated. When the stoker is ready, he/she rotates the left
(or right if you prefer) pedal to the top of the pedal stroke. The captain now clips into
that pedal.

Now it is time to shove off. The captain should stand on the raised pedal to start the
bike rolling. Put the other foot (that is not currently clipped in) on top of the other
pedal and complete a few pedal revolutions to get the tandem rolling. Now the
captain may clip their other foot in.
