The 900i is a no-nonsense, internally routed dropper post from ExaForm — a brand backed by KS, one of the most trusted names in dropper post technology. Rated for e-bikes and built to last, it delivers smooth, consistent performance at a price that punches well above its weight.

Construction is all-aluminium with a sealed hydraulic cartridge, forged head parts, and a one-piece mast — features you'd typically expect to pay more for. The sealed cartridge keeps contaminants out for long-term reliability without the need for user servicing.

Supplied complete with a Westy remote lever and cable housing — everything needed for a straightforward installation on any internally routed frame.
