Direct Mount Adapter Instructions

The Direct Mount Adapter allows you to use direct mount front derailleurs on frames with standard seat tubes (31.8 or 34.9mm OD). We’ve designed two versions: one for use with frames with 100mmwide bottom bracket shells (FS1322), and the other for use with standard 73mm-wide bottom bracket mountain frames (FS1323). The Direct Mount Adapter is compatible only with Shimano High Direct Mount front derailleurs. It is NOT compatible with SRAM S1, S2 or Shimano E2 derailleurs.

WARNING: Read these instructions completely before beginning installation of this product. If you lack the knowledge or tools to perform installation, please have your local professional bicycle mechanic perform the installation. Improper installation can result in loss of control or damage to the bicycle and/or serious injury or death to the rider.

• Loosely attach the derailleur to the Direct Mount Adapter using the bolt provided with the derailleur and a 5mm hex wrench (fig. 1)

• Attach the clamp to the frame using a 4mm hex wrench (fig. 2). For 31.8mm outer diameter seat tubes, use the included shims. Snug the clamp bolt, but don’t tighten it fully yet

• Align the derailleur according to the manufacturer’s instructions. As a general rule, the derailleur should be parallel to the chainrings and should sit about 1mm above them (fig. 3). Check manufacturer specifications

• Fully tighten the clamp bolt. Torque: 4–5 Nm

• Fine-tune your derailleur height using the derailleur bolt (fig. 4).

   When finished torque the derailleur bolt to manufacturer’s specifications
