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.
30mm Aft offet adjustment The seatpost can be adjusted backwards over a 30mm distance, i.e. - 5 to - 45mm from the seat tube centre line. This is not a reversible E-Post.
Easier for aft adjustment Adjustment is easy with only one easily accessible Titanium bolt.
