11. If equipped with a computer, connect any wire, pickup, or head. Secure wire with zip ties or tape, so it
doesn’t rub the tire or catch on the brake.
12. Tighten the round couplers with the S&S coupler wrench, and Santana oval couplers with an allen wrench.
13. Install the front seat/seatpost assembly.
14. Install the rear handlebar assembly, tightening the two bolts in the middle of the adjustable stem, and tighten-
ing the handlebar bolts.
DRIVETRAIN
15. Unwrap the chain from its protective wrapping on the chainstay.
16. Install the rear wheel with the cassette on the drive (right) side and the quick-release lever on the timing side
while draping the chain over the smallest cog. (For Arai drum brakes, the bolt on the brake anchor arm on
the wheel must be positioned in the brake anchor slot on the frame. Never attach the bolt to the frame.
17. On the drive side, install the triple chainwheel crank arm to the rear bottom bracket spindle while pulling
the chain onto the smallest chainwheel. Install the crank arm without chainwheels to the front bottom bracket
spindle. The splines on the crank arms and the bottom bracket spindles must line up exactly. Serious dam-
age can occur if they aren’t aligned.
All crank bolts tighten clock-wise and must be tightened as rmly as possible. (Tightening torque is 305
– 435 in.lbs. / 35 – 40 Nm.)
18. The crank arms might be longer on the front of the tandem. The lengths of most crank arms are stamped on
them, i. e. 170 or 175. On the timing side, install the (long) single chainwheel crank arm to the front bottom
bracket spindle, 180° from the one opposite it. Install the (short) single chainwheel crank arm to the rear
bottom bracket spindle, 180° from the one opposite it.
19. Install the pedals by attaching the right-hand (clock-wise) thread pedals on the right side, and the left-hand
(counter clock-wise) thread pedals on the left side.
20. Install the timing chain with the front and rear cranks in phase.
21. Tighten the timing chain by rotating the eccentric downward, until the chain is tight, but not so tight that it
vibrates as the cranks are turned.
22. Firmly tighten the two allen bolts under the eccentric bottom bracket shell, being sure the eccentric is cen-
tered, left and right, in the bottom bracket.
BRAKES AND DERAILLEURS ETC
23. (Install the hydraulic caliper to the frame mount adapter. Install the master cylinder to the timing side cable
guide of the down tube. Clip the hydraulic line into the cable guides on the bottom of the down tube, bot-
tom tube, and top of the chain stay. Be sure there are no sharp bends or kinks in the line.)
24. If equipped with a cable operated hub brake, use the slotted cable guide in the center of the down tube,
center of the eccentric, front, bottom bracket shell, and cross to the timing side of the rear bottom bracket
shell, positioning the Teon® tubing at the bottom bracket shells. Pull the Santana/Arai drum brake quick-re-
lease cable end over the pivoting brake arm.
25. Install the front, linear pull, rim brake arm to its fork mount or the side pull, caliper brake unit to its fork cen-
ter hole with an allen wrench.
26. Thread the rear rim brake cable through the slotted cable guide on the side of the front top tube, and screw
the barrel adjuster into the guide. Thread the cable through the next slotted guide, and join to the cable
Quick Connect attached to the rear brake.
