Instructions for Using the Ortlieb Big Zip for Shipping a BOB Trailer

Packing the Yak Trailer in the Big Zip

• Begin by removing the trailer wheel, fender, and trailer fork from the BOB trailer.
• Snap the included dropout protector over the trailer wheel dropouts (Fig.1).
• Unzip the Big Zip, and slide the rear end of the BOB trailer into the side of the Big Zip were the zipper slide is in its open position (Fig. 2). 
  Pull the zippered edges up and over the bottom rail of the BOB trailer.  This is a tight fit so work the zippered edges up and over the front end of the bottom rail of the BOB until it is entirely over it (Fig.3).
• With the BOB trailer partially inside of the Big Zip, put the pads onto both of the BOB trailer’s fork tabs.  This is done by slipping the fork tab into the slit in the flat section of the pad and wrapping the cord around the rail.  The open end of the loop goes over the cord locker.  Tighten the cord locker to lock the pad in position (Fig.4).
• Push the BOB further down into the bag and then begin working the zippered edges up and over the top rail of the BOB trailer (Fig.5).

Packing the Ibex Trailer in the Big Zip

• Begin by removing the trailer wheel, trailer fork, and suspension swing arm from the BOB trailer.
• Put the pads onto the BOB trailer’s fork tabs.  This is done by slipping the fork tab into the slit in the flat section of the pad and wrapping the cord around the rail.  The open end of the loop goes over the cord locker.  Tighten the cord locker to lock the pad in position.
• Unzip the Big Zip, and slide the rear end of the BOB trailer into the Big Zip.  
• Pull the zippered edges of the Big Zip up, over, and around the BOB trailer (Fig.6) 

Packing up the Trailer Fork, Wheel, Fender, & Suspension Swing Arm (Ibex)

• The additional parts of the BOB trailer can be packed in with the BOB trailer or separately with your bicycle if you are traveling with your bicycle packed in a bike case.
• To pack the additional parts of the BOB trailer inside the Big Zip, we recommend putting these parts inside your BOB DrySAK or Travel Bag.  Put your DrySAK or travel bag inside of the BOB trailer.  This will both protect the parts and prevent them from scratching your BOB.
• With the suspension swing arm of the Ibex trailer, we recommend snapping the dropout protector over the trailer wheel dropouts.
• When packing the additional parts of the BOB trailer inside a bike case with your bike, cover the parts with a protective covering and secure them in place to prevent the parts and your bike from scratching each other. 
• Depending on the size and configuration of your bike case, you may be able to leave the BOB QR on your bicycle’s rear wheel and then mount the trailer fork onto the QR in a position suitable for shipping. 

Additional Packing Ideas & Instructions

• Once your BOB trailer is inside of the Big Zip, you will have plenty of additional room to pack all of your travel and bike touring gear.
• Be sure to pack some soft items such as a sleeping bag, pad, and clothing behind the rear end of the BOB trailer.  This will fill in the empty space behind the rear of the Ibex trailer’s suspension tower or the Yak trailer’s luggage stop (Fig.7).  
• Additionally, we recommend packing soft items in the space along both sides of the BOB trailer to provide additional padding.
• Pack more delicate and solid items such as cameras, water bottles, stoves, tools, and the additional parts of the BOB trailer inside of your DrySAK or travel bag.
• The Big Zip Measures in at 38” x 20” x 11.8”.  This is right at the limit of most airlines oversize limit and is generally always accepted as standard luggage.  Also be aware of weight limits, 50lbs is generally the overweight limit. The Big Zip weighs 4 lbs.  The Yak weighs 12lbs.  The Ibex weighs 15lbs.  Pack your travel and bike touring gear with this in mind.  Put extra weight in with your bicycle case.
