The PRO Tharsis 3Five is an infinite-travel dropper seat post for weight conscious Cross Country or Endurance mountain bikers. It features 100 mm of travel and is suitable for internal cable routing.
All models boast a 3D-forged aluminium construction with an oval shaft made of AL 7050. But while the lower of the version with 27.2 mm diameter uses AL 6061, the lowers of the 30.9 and 31.6 mm models are made of AL 7075.
Nevertheless all versions have their light weight in common which is also achieved by a lighter cartridge, titanium bolts and a revised collar. New as well is the 2-bolt saddle clamp.
Total length: 400 mm
