How it Works:

Buddybar was originally designed for getting the efficiencies of riding a tandem, but doing it at a fraction of the cost. When testing Buddybar, we found many more uses, most of them pertaining to the training of new and seasoned riders. This training includes: pacelining, cadence training, heartrate training, drafting, and more.

Set up:

  • The front bicycle attaching assembly connects to the frame rails at the back of the saddle. This will be the “captain” bicycle.
  • The rear bicycle attaching assembly connects to the stem of the bicycle. The stem must be a 1″ or 1 1/8″ stem. Quill or threadless should not matter.
  • Buddybar has a quick coupler on both ends and connects both bicycles together, front to back (tandem style), which gives the immediate advantage of built in draft. That advantage is a one person aerodynamic profile, and two rider’s power.


Captain Attaching Hardware Installation

  1. Take the angled T-bar and step plate, positioning so the angled T-bar comes straight out of the back of the saddle (bending may be necessary to make it straight as some saddles have a little more bend in their frame rails).
  2. Take the bolts provided and cinch down to the frame rails of the saddle.
  3. Take male end of attaching hardware and attach to the angled T-bar. This can be configured up or down, but we have found if it is down, there is more room for movement of the Buddybar.

Stoker Attaching Hardware Installation

There are two types of stems that are used on most bicycles today:

Quill stem

The quill stem has been around much longer, and it usually has a bolt that goes through the top of the stem down into the front fork.

Threadless headset

The threadless headset is the newer of the two, and it has a “top cap” with a bolt going through the top; it screws into a “plug” that is in the front fork. It also has a stem that mounts to the fork with one or two attaching bolts and some spacers.

Quill Stem:

  1.  Remove stem and handlebar by using a 5mm or 6mm allen wrench, loosening the bolt that is on the top of the stem.
  2.  Pull stem and handlebar assembly from headset.
  3.  Take a large crescent wrench and unscrew nut on top of the headset.
  4.  Remove headset nut and spacer from headset.
  5.  Install buddybar connecting rod assembly either right side up or upside down(whichever has the most clearance.
  6.  Screw on and tighten headset nut.

Threadless headset:

  1.  Remove top cap.
  2.  Loosen stem bolts.
  3.  Pull stem and handlebar assembly from fork.
  4.  Install Buddybar connecting rod assembly with head down or head up (head down usually gives more clearance). You may need to remove a small spacer to allow room for the connecting rod assembly.
  5.  Replace stem and handlebar assembly onto fork (do not tighten stem nuts yet).
  6.  Replace top cap. Screw down until there is no play in the headset (holding the front brake helps to determine play).
  7.  Straighten stem and handlebars and tighten stem bolts (usually to 4Nm).
