Dropper Post Yes


A fully mechanical dropper post which -like a few dropper posts by other manufacturers- uses a replaceable air cartridge to work as a return spring. Other manufacturers are pushing the limits of how much drop you can get by going for 150 or even 170 mm of drop, but Pro has opted for a respectable 120 mm. In the real world, this will be more than enough for most people apart from perhaps the very tallest or most extreme riders.

The Koryak post is available in two of the most frequented diameters, notably 30.9 and 31.6 mm. Operation works via a thumb shifter which can be mounted on either the left or right of your bars, or using a Shimano i-spec II compatible Firebolt-like shifter. This last option combines the best of a 1x11 drive train or an XT/XTR groupset with Synchronised Shift.

L’essayer c’est l’adopter

C’est la deuxième tige Koriak qui termine sur mon vtt et je ne pourrais plus m’en passer ! Vélo commandé ( nouveau Santa Cruz Blur) et hop aussitôt la tige Pro commandé aussi. Fiabilité exemplaire par tout temps et température, je l’ai reprise les yeux fermés.


  • Fiabilité
  • Entretien
  • Fixation de la selle
  • Tarif


  • Léger jeu après quelques mois mais mineur

Très bon article

J’utilise cette tige de selle en remplacement d’une version hydraulique. L’installation est facile, Les matériaux semblent être de bonne qualité. Il faut bien serrer au couple recommandé l’écrou central afin d’ éviter toute rotation involontaire. Le rapport qualité/prix est remarquable. Les coûts de maintenance le seront également. A voir dans la durée ce que cela donne...


  • Efficace
  • Économique
  • Bonne qualité
  • Un seul écrou pour le serrage
  • Très faible coût de maintenance


  • Légère flexion, manque de rigidité ?

Detailed product description

Dropper seat posts are becoming a regular sight on bikes with 120 mm of suspension travel or more, and something we recommend for riders who're going for rougher trails or who would like to ride in a little more playful manner. Even XC racers at the very top realise the potential of the dropper, and choose to use them during the World Cups for instance. Starting this fall, PRO (the accessory brand by Shimano) will start to offer one such seat post under the well-known Koryak component range.
