Vibration Dampening The seatpost is fully “isolated” from mini-impacts and vibrations by 3 elastomer blocks. 2 of them are placed inside and secure the seatpost inside the frame. They can be expanded by tensioning the adjustment bolt with a maximum tightening torque of only 5Nm. This solution is much more durable for carbon than a conventional collar requiring 20Nm tightening torque. The third elastomer block is placed between the frame and the post. This elastomer is inserted 40mm inside the seat tube and forms a 9mm thick pad outside.
Comfort Elastomer blocks absorb the vibrations through a slight inflection of the seatpost backwards, thus greatly improving cyclist comfort. The most flexible elastomer (grey) provides the same deformation ratio as a conventional LOOK Ergopost 4 seatpost at maximum height. High deformation = maximum comfort (Diagram 1). The use of three elastomer grades of different densities make it possible to adjust the vibration transmission. The firmest elastomer: the black colour grade provides the same deflection as the 2007 Road E-Post, with only one 3-mm elastomer to filter the vibrations.
The two other elastomer units (grey or red) provide greater vibration dampening.
Anti-rotation and non-slip adjustment The seatpost is an abutment against the frame and secured, eliminating any possibility of slippage. As the E-Post and integrated seat tube sections are not round, the saddle remains fully aligned at all times.
New: Internal DI2 Battery compatibility All E-Post TI, R5 and R32 now come with a bracket for the internal Shimano battery. This part is located under the E-Post and makes it possible to clip your battery very easily. A rubber washer is also supplied to hold the bottom of the battery and prevent it moving laterally, which could create unpleasant noise. These 2 parts are also available independently (Ref: 6456) for cyclists who already have an E-Post.
Saddle Clamps for R32 and R5 for Carbon Rails The 2 E-Post R 5 and R 32 are compatible with the 7×9 mm carbon rail saddles using a specific saddle clamp provided separately (LOOK Code: 6036) The clamp for round rails is also available independently (Ref: DTAC/0266791).
Reversable The saddle can be positioned +/-5mm in the forward/backward direction from seat tube centre line. This E-Post is reversible and utilizes a 360° multi-directional saddle adjustment clamping system.
Easy angle seat adjustment With only one easily accessible bolt, the clamps can be loosened and the seat can be adjusted. Gradations on the post are provided for precise adjustment.
