Tyres
Quality tyres are vital for good traction and control while
accelerating, turning, and braking. Each brand of tyre has
its own individual mix of puncture protection, rolling resist-
ance, pressure rating, and durability. Finding the one that
suits your riding style best is the challenge. Tyres should
always be inflated according to the range marked on the
sidewall, never above the maximum recommended, and
they should be checked regularly. Worn tyres should be
replaced. Lower pressure results in a more comfortable
ride, but at the expense of higher rolling resistance. Bal-
loon tyres are now available that combine relatively low
rolling resistance, puncture protection, and a smooth ride;
they are well worth considering. With two adults on the
tandem we recommend having the tyres inflated to the
upper limit of the marked pressure range.
NOTE: It is important that both tyres on your tandem are
inflated to the correct pressure.
Wheels and removal
The wheels on your tandem are made up of three
components; the rim which holds the tyre on, and
provides a braking surface, the spokes which support the
hub in the middle of the rim, and the hub around which
the wheel rotates, providing a means to driver, with disc
brakes, a means of braking. All three parts should be
checked regularly (as per maintenance table), rims should
be checked for wear and straightness, spokes that they
are all at correct tension and none of them are broken,
hub for play in bearings and signs of damage to flange.
Rear wheel removal
Rohloff
Remove the clickbox from the left side of the hub. It is
recommended that you shift to the 14th gear before
doing this to help with reassembly.
When reinstalling the Rohloff you must orienatate the
torque arm such that it aligns with the lower disc brake
mounting bolt.
Alfine mechanical
Remove the shifter cable form the cassette joint by shifting
to the highest gear (8 or11 depending on the hub). Once
the cable is removed, undo the wheel nuts with a 15mm
spanner, and the wheel should slide out. When reinstalling,
ensure the wheel is fully seated in the drop outs and the
disc brake (if fitted) is aligned with the caliper. Tighten the
bolts to the recommended torque (Appendix A).
Alfine Di2
Before removing the wheel, it is essential that the Di2
cable to the hub motor unit is disconnected using the
Di2 tool supplied with your bike. Then follow the same
instructions as per the mechanical Alfine hub.
