Construction

If you are looking for a weight-optimized seatpost for your Specialized Tarmac SL8, we have the perfect seatpost for you: Like all our products in the TLO series, our straight full carbon seatposts are hand-wound (about carbon) from the best prepregs available on the market to suit your weight and riding style. Compared to standard carbon seatposts, these lightweight seatposts are designed to be more vertically compliant without sacrificing lateral or torsional stiffness, resulting in a noticeably more comfortable ride without losing energy. The head clamps the saddle frame at 4 points. Thanks to the slightly rounded aluminium clamping parts and the large contact surface of the carbon half-shell, even sensitive carbon saddle racks are not subjected to excessive stress. The saddle mount is designed for both oval and round saddle racks.

The 5 mm Ti6Al4V titanium bolts are designed as expansion bolts to withstand stresses without damage.
The tube is only constructed from up to 23 extremely thin layers of carbon fibre prepreg in the particularly stressed areas. In the stress-free zones, this number drops to 7 layers. Unfortunately, this sophisticated construction is very complex and cannot be realised in Asia. Cheap “Chinese seatposts” are only built with a constant wall thickness, which greatly simplifies production but adds unnecessary weight. For lightweight carbon seatposts in particular, countless test bench trials are necessary to work out the optimum design for each length and diameter.

Surface options

All our lightweight carbon seatposts are unpainted to avoid adding unnecessary weight. Above all, the epoxy surface is much more resistant than any paint finish, so it won’t get scratched as quickly. All our lightweight carbon seatposts come in the current matt look. TLO seatposts can be ordered in UD. With UD (unidirectional), all carbon fibres run in one direction. This gives the surface a uniform black, almost painted look. In general, UD carbon parts are a few grams heavier than 1K carbon parts. You can find out more about UD here

Color options

To create the perfect look on your bike, all TLO seatposts are available in 3 different logo colours: Schmolke Edition (red / white), Black Edition and White Edition.
