All TLO (TheLightestOne) 1K carbon seatposts are handmade in Germany. Just like all other products of our TLO range our seatpost is manufactured to suit your personal weight and riding style using the best prepregs available in the market. Its head clamps the saddle’s rails on eight points. The alloy parts have chamfered edges, which, together with the large supporting carbon fibre surface, ensures that even fragile carbon rails are not unduly stressed. The 5 mm Ti6Al4V titanium screws are waisted extension bolts, strong enough to even withstand rough terrain mountain bike use.

The actual tube’s highest stressed sections consists of up to 17 layers of extremely thin carbon fibre prepreg, while its less stressed sections are sufficiently strong with as little as 9 layers. Unfortunately this is a complicated design, too complicated for cheap Asian production. Seatpost built to a price in China as a rule come with constant wall-thickness. This makes production easy, it also makes the resulting seatpost heavier than necessary. Seatposts in particular require hundreds and hundreds of destruction tests to arrive at the lightest possible solution for every length and diameter without sacrificing the final products strength. We do of course also include rider’s weight into our design equations; light riders don’t need to carry the extra weight of a standard seatpost designed for a user much heavier than they are.

Our seatposts are reinforced where they are stressed by the seat clamp, hence their range of adjustment is limited. Do not buy a long seatpost to cut it to size. We want to adjust strength and length of your seatpost to your requirements as good as possible; hence we need the seatpost length as measured from the top of the frame to the middle of the saddle’s rails.

Weave options

TLO seatpostes can be ordered in 1k or UD weave. 1k is the classic carbon look with biaxially woven fibres. UD (unidirectional) describes a more subtle all-black “non-woven” carbon look where all fibres run in one direction. In general UD carbon parts will be a few grams heavier compared to their 1k counterparts. Click here to see the UD version of our TLO seatpost

Color options

To allow the perfect match for your bike, all TLO seatposts are available in 2 different logo color options: black edition and standard red/white team edition

Please note: Longer seatposts require more raw material, therefore we have to charge 460 € for the posts longer than 350 mm.

TLO seatpost inner diameter fits Di2 batteries.
