Dualdrive Hub - Bike Friday Family Tandem Traveler User Manual

DualDrive™ Hub
Using Your Optional DualDrive Hub
For many bike travelers, the DualDrive hub offers the perfect com-
bination of wide gear ratios, simplicity, and durability.
As with a standard drive train, there is no single best shi�ing order
on a DualDrive equipped bicycle. Experiment and find what works
well for you. A cyclist with a standard drive train must be conscious
to avoid cross-chaining, which occurs when you shi� into a small
gear in front and a small one in back, or a vice versa. Cross-chaining
can cause excessive wear on your components. Since cross-chaining
is not an issue with the DualDrive hub, any gear combination is
acceptable.
Other benefits include being able to shi� the hub when standing
still at a stop light or the bo�om of a hill. Simply shi� the internal
hub to a lower gear (without even pedaling) and off you go.
The DualDrive single-sided shi�er has an icon depicting uphill,
flat, and downhill terrain to identify low, middle, and high gears.
If your Bike Friday travel bicycle is equipped with different shi�
levers, the le� hand lever controls the internal hub. Pulling the
cable in shi�s the hub to a higher gear for descending hills. For
those who are curious about the gear ratios, adjust your gear inches
for low gear by 73%, mid-range 100% (1:1), and high gear 136%.
Maintenance
Your DualDrive hub requires li�le maintenance. The shielded
bearings are very durable, and the internal mechanism is highly
reliable. Periodically applying a li�le oil to the shi�ing rod is all
that is required. If you ride casually, then once a year is sufficient. If
you ride a lot more or in poor weather, then every six months will
suffice.
To lubricate the rod, remove the click box and the shi�ing rod (see
the following directions). Lay the bike on its le� side, or remove the
wheel and then lay the wheel on its le� side. Dip or coat the shi�ing
rod in a good quality synthetic oil such as Phil Wood Tenacious Oil.
Do not over lubricate!
Let the bike or wheel lay on its side overnight. Then re-a�ach the
shi�ing rod (do not over tighten) and the click box.

DualDrive Hub

1. The Click Box
The DualDrive shi� cable
connects to a grey and/or
black box a�ached to your
rear hub axle above the
rear derailleur. To install
and remove the rear wheel
you will need to detach and
reconnect this click box to the
axle in a few simple steps.
Start by shi�ing the DualDrive hub into the lowest gear (uphill
icon, or repeatedly press the small lever on STI shi�ers).
2. Attachment Button
The small black bu�on on
the click box is used to a�ach
the box to the axle. In the
up position the box is con-
nected.
To remove the click box,
press this bu�on down until
it is flush with the top of the
box.
3. Remove Click Box
With the black bu�on down,
the click box should just slide
off of the axle end. The click
box will remain connected to
the shi� cable.
