Älsak is available in three different sizes, depending on the STD seatpost tube diameters of 27.2 mm, 30.9 mm and 31.6 mm. All of them are offered in the following lengths: 250mm, 300mm, 350mm and 400mm, special lengths up to 500mm are also possible upon request.


    – Offset: 0mm
    –Forged Carbon Fixing Technology
    – Titanium bolts and pivots
    – Material: Intermediate modulus carbon
    – Available with different layup options
    – Weight reference 27,2mm and 250mm version: 69,5 g (Lightweight); 90g (Performance)


Aware that nowadays users are more aware of their needs on their bike, we have developed two versions of layup in the construction of our components, using the best technology applied in both but with small differences so you can get the most out of your GEMINI.


For those who want to get the most out of every pedal stroke, making the most of the stiffness of the components, we have developed a special high-performance layup, which although it adds 20-30 grams to the set compared to the Ultra Light version, it will allow you to make the most of every watt of energy your body generates. Designed for XC use for a rider up to 120 kg.


For the weight freaks, the Ultra Light layup version has been developed and optimized to the maximum to shave off any extra gram of weight in the Lightweight layup version, creating one of the lightest seatposts on the market, with a record weight in the 250mm 27.2 version of only 66 grams while maintaining a spectacular aesthetic. Designed for XC use for a rider weighing up to 90 kg.
