Easton Bike

Installation of Seat Post

• Carbon Quills: DO NOT apply grease to carbon quills. Also, clean any existing grease from the inside of the seat tube prior to installation.
• Aluminum Quills: DO apply a small amount of grease to aluminum quills prior to insertion. This will ensure that the quill does not freeze and lock into the seat tube over time.
• Insert the seat post into the seat tube.

  Do not use a rotating motion. Scratches on the seat post can cause stress concentrations that could result in seat post failure.

• The seat post must be inserted into the seat tube a MINIMUM of 70 mm (2.75 inches) for proper post life. However, many frames require more than the minimum 70 mm insertion. The seat post must be inserted deep enough into the frame to ensure that the bottom of the seat post extends past the bottom edge of the top tube (see Figure 1).

  Failure to insert the seat post far enough into the frame could result in seat post failure.

IMPORTANT: Easton carbon seat posts are constructed with Relief Area DesignTM (RAD), a patented Easton design feature. The relief area is a flattened section of the seat post quill that protects the post from being pinched when the seat tube collar is tightened (see Figure 2). Because the relief area does not extend the full length of the quill, it is important to make sure that your seat tube collar is positioned within the relief area. If you insert the post too far into the seat tube, you may clamp down on an unrelieved area of the quill.

Clamping the seat post in an unrelieved area of the quill could damage the quill and result in seat post failure. Over-tightening the seat post collar could damage the seat post quill and result in seat post failure.

• Before tightening the seat tube collar, make sure that the upper lip of the collar does not touch the seat post (see Figure 3).

  If the collar lip touches the seat post, the post could be damaged during tightening, which could result in seat post failure.

• Tighten the seat tube collar bolt. Recommended torque is 60 in-lbs (6.72 Nm). Maximum torque must not exceed 75 in-lbs (8.4 Nm).

Installation and adjustments of saddle

• The saddle rail slots are designed for saddles with standard 7 mm rails.
• Put a small amount of grease on the threads of the saddle clamp bolt.
• Adjust the seat angle first, then the fore-aft position.
• Torque the saddle clamp bolt to 100 in-lbs (11.2 Nm).

  IMPORTANT: Recheck bolt torque after 50 to 75 miles of riding. Incorrect clamping of the saddle clamp bolt can lead to seat post failure.

Maintenance

Seat posts must be maintained and inspected frequently and closely. In particular:

• Inspect for dents, bends, deep scratches or gouges before each ride. If any are visible, do not use the bicycle until the seat post has been replaced. Seat posts may be severely weakened even if no damage is visible.
• Replace any deeply scratched or gouged posts immediately. Destroy any seat post you replace for safety reasons.

  Scratches on the seat post can cause stress concentrations that could result in seat post failure.

  After a major impact or accident, even if no dents, bends or scratches are visible, have a dealer inspect the seat post before using the bicycle.
