Packing a 24" x 18" Bilenky Signature Tinker Tandem
Packing a complete tandem in a single S and S hard case (26"x26"x10") is considered by some cyclists to be to difficult. It requires more disassembly and patience to fit all the parts into one case. Using two cases is much easier and faster.
into One S and S Hard Case.
If you need the compactness of a single case and are willing to invest the extra time in packing then this method works great.
Removing the fork
Additional components used to make disassembly and packing easier.
How long does it typically take?
- Bruce Gordon gear cable splitters make dealing with derailleur cables easier.
- Sugino Autex self extracting crank bolts allow removal of the crankarms by loosening a single 6mm allen bolt. No pullers or special tools are required to remove the cranks.
- A Craig Super Link reusable chain connector allows the chain to be easily removed without tools.
- A wireless computer eliminates wires from the fork to the handlebars.
- Disassembly and packing of this bike takes about 30-40 minutes once a packing method has been established and it has been practiced a few times.
- Reassembly including unpacking takes about 45-60 minutes. I make a photographic record of each step so I can refer to it if needed.
- In a hurry? The times given above are very conservative. Frequent travelers should be able to reduce these times significantly.
The frame in pieces
Place the front frame section in the case.
Place the rear wheel in the case with the cogs down. Tilt the wheel so it is down in the lower left corner where there are no frame tubes. This makes room for the wide part of the rear frame section. (Place a piece of hose slit lengthwise on one side over the tubes for protection in case they come in contact with the teeth)
Place the rear frame section with the dropouts in the lower left corner. (Be sure to use a slit hose to protect the frame where the frame tube contacts the rear axle)
Place both handlebars as shown. It may be necessary to rotate the rear wheel so the opening in the spokes will allow the handlebar drops to pass through. There shouldn't be any force against the spokes when the bars are in the correct position. Lift the wheel and rear frame section as necessary to position the bars.
Lift the wheel and place the seats as shown. (Small items such as loose frame tubes, seats, seat posts, cranks, and fork can be placed in any open area as required)
Place the forks and three loose tubes in the case as shown. (Small items such as loose frame tubes, seats, seat posts, cranks, and fork can be placed in any open area as required)
Place the chainrings and seatposts in the case as shown. (Small items such as loose frame tubes, seats, seat posts, cranks, and fork can be placed in any open area as required)
Place the front wheel on top. Note that the handlebar drop is over the wheel. To close the lid it is necessary to work the tire into the lid as it is closed.
Protect your bike
- Use S and S tube covers or other suitable material to prevent minor scratches. This packing sequence is shown with tube covers removed for clarity.
- Use additional packing material between frame tubes and objects which could dent or scratch them such as an axle, freewheel or another frame tube. A heavy rubber hose slit lengthwise and placed under the tube cover works good.
- Always use 3 or 4 S and S compression members with a hard case to reduce the possibility of damage due to careless handling. When this bike is packed there is no pressure on the bike from the case. The compression members are taller than the packed bike so they protect the bike if something is stacked or dropped on the face of the case.
- Wrap all small items in rags or other suitable packing material to prevent them from rattling and scratching other parts.
Not all tandems can or should be packed using this technique. Some experimentation is typically required to develop a suitable packing method . This packing sequence is offered only as an illustration of what can be done.
