Video: How toassemble a fully equipped Santana Touring Tandem out of the Airliner case.

 

Required tools

  • 4, 5 and 8 or 10 mm Allen wrench
  • Pin-spanner tool to tighten the chain if necessary (e.g. Park-Tool SPA-1)
  • S&S coupling wrench (no longer needed with the new Z-couplings)

Tandem assembly


  1. First remove all parts and foam layers (tip: stack them in the order in which they are removed).
  2. To begin, insert the stoker handlebar into the stoker stem on the captain seat post, fix it with the 5 mm bolts on the side and tighten the 4 mm bolts on the handlebar. Caution! Do not overtighten to avoid damaging the handlebars.
  3. Then insert the captain seat post into the captain seat tube, fix it and place the front frame on the captain saddle and stoker handlebars.
  4. Next, loosely screw the bottom tube to the front frame. For S&S couplings, it is recommended to screw the top tube and lateral tube to the front section first. For the lateral tube, the tube end with the smaller distance to the bottle mount is positioned at the rear. If the tandem is equipped with a rim brake at the rear, care should be taken to position the cable guide correctly on the top tube. The cable guide would then be located at the rear left of the top tube in the direction of travel.
  5. Now the stoker saddle is inserted into the rear triangle, turned around and connected to the bottom tube. The stokers handlebars keep the tandem from tipping over sideways. With S&S couplings, instead of the bottom tube now the top and lateral tube is connected to the rear.
  6. Only now the top tube is inserted between the rear and front frame sections. For S&S couplings, the bottom tube is inserted in this step. Only when all tubes are in place the 5 mm Allen screws in the Z-couplings are tightened to approx. 8 Nm (a coupling wrench is required for S&S couplings). This prevents unwanted tensions caused by uneven tightening of the screws.
  7. Next, the cranks are mounted. The length of the crank tells you which of the left cranks belongs to the captain and which to the stoker. The captain crank is 5 mm longer than the stoker crank.
    1. At the beginning, the rear chain is placed on the chainring of the stoker crank. The crank is screwed onto the bottom bracket axle with an 8mm Allen key. Make sure that the notches on the inside of the crank fit onto the notches on the bottom bracket axle. The crank is now tightened until you feel a sudden, strong resistance (about 30 Nm!).
    2. Next, the cranks of the timing belt/chain are attached offset by 180°. If the tandem is equipped with a belt, it should already be on the belt blade when the cranks are screwed on and the cranks should be lined up synchronously with each other. Alternatively, the belt can also be fitted after the cranks have been screwed on, but must then be adjusted to the correct tightness via the eccentric using the Pinspanner tool (it should be possible to press the belt in slightly by about a finger's width). A timing chain can be fitted after the crank has been mounted.
    3. Finally, screw the right captain crank to 180° offset to the already mounted cranks of the timing drive.
  8. Next, the quick-releases are inserted into the hubs and placed in the fork and rear triangle. The lever of the quick release is located on the side of the disc brake. On the front wheel, the lever is also on the side of the rear resp. front disc brake. Always close the lever (with resistance from a position of approx. 45°) in the opposite direction to the direction of travel.
  9. The tandem is now placed on the wheels so that the captain handlebar can be placed on the steerer tube.
    1. First remove the top cap from the steerer tube before attaching the stem and handlebars.
    2. Then replace the top cap of the headset and tighten until the fork has no more play (only approx. 1-2 Nm - do not tighten completely!). Adjusting the headset play is not necessary if a locking collar on the steerer tube ensures that the fork remains fixed when the handlebars are removed.
    3. Now align the handlebars with the front wheel and tighten the 4 mm Allen screws on the side of the stem on the steerer tube.
    4. Align the drop bars (racing handlebars) roughly parallel to the ground / top tube and tighten the stem bolts to approx. 6-7 Nm.
  10. Now attach the cables.
    1. Starting with the shift cable of the front derailleur, cross the front of the head tube, on the right side (in the direction of travel) in the right-hand barrel adjusters on the down tube.
    2. The cable for the rear derailleur is also crosses the head tube to the left side and inserted or screwed to the barrel adjusters. The middle barrel adjusters is provided for the brake cable to the disc brake.
    3. If the tandem is equipped with an electric shifting, there is no need to attach the shifting cables. Instead, only one cable for the front and the rear derailleurs needs to be plugged at the down tube and at the captain and stoker bottom brackets.
    4. The brake cable for the rear brake is also routed in front of the head tube to the left side and inserted or screwed into the left barrel adjusters.
  11. Now the cables running from the handlebars to the rear can be connected under the bottom tube with the cables coming from the rear. These cross under the oval bottom tube!
    1. Place the rear brake cable under the captain bottom bracket through the left cable guide and screw it together by hand with the left brake cable coming from the rear.
    2. The shift cable of the rear derailleur is led from the front through the middle cable guide under the captain bottom bracket and connected with the shift cable of the rear derailleur coming from the right, rear side. Make sure that the lowest gear is selected so that the tension of the cable is minimized.
    3. Finally, the front derailleur cable is routed under the bottom bracket through the right cable guide and connected to the front derailleur cable coming from the middle, rear side. Again, make sure that the front derailleur is located above the smallest chainring to minimize cable tension.
  12. Then mount the front brake by reattaching the brake caliper removed from the fork to the post on the fork. In the case of a V-brake, make sure that the return spring of the brake caliper is inserted into the same hole as on the other side.
  13. Finally, the brake cable is hooked in. If the fork is equipped with a racing bike brake caliper, the plug located on the brake caliper is passed through the fork steerer tube and tightened from the rear with the sleeve nut (hexagon socket, approx. 8 Nm). The brake body is then closed.
  14. If the tandem is equipped with extras, such as a rack, lowrider, mudguards or bottle mounts on the stoker lateral tube, these are then mounted.
  15. The tandem is now completely assembled. Before driving off, it is essential to ensure that the brakes and shifting are working correctly. If necessary, these must be adjusted.
    1. If the pressure point of the front brake is too late, the barrel adjuster on the brake cable can be unscrewed slightly to lengthen the brake cable and increase the tension.
    2. If the tandem is equipped with a rim brake at the rear, the adjustment is done in the same way as at the front.
    3. The brake pads of the front brake should have the same distance on both sides of the rim. The tension of the spring for the respective brake caliper side can be readjusted via the 3 mm Allen screw on the side.
    4. In the case of a disc brake, disassembling and reassembling the tandem should not change anything. However, if adjustment is required, the brake piston can be moved closer to the brake disc using the 5 mm Allen bolt on the inside of the brake caliper. Likewise, the barrel adjuster on the brake cable in front of the brake caliper can be slightly unscrewed. Both adjustments result in an earlier pressure point of the disc brake.
    5. The rear shifting is adjusted by turning the barrel adjuster on the underside of the down tube. Unscrewing the adjuster will pull the chain down on the cassette, while screwing the adjuster will pull the chain up on the cassette.
    6. Adjusting the front derailleur is done similarly by turning the barrel adjuster on the underside of the down tube.
    7. If the tandem is equipped with an electric shifting system, the shifting is adjusted via the shift indicator on the handlebars, via the smartphone app, or by connecting it to the computer.
    8. Before riding, always check the tight fit of the handlebars and the saddles.
