The KS Zeta post could start a road dropper revolution

Cut-to-length dropper post with 35/50mm of travel

Lurking away in a corner at the 2016 Bike Place trade show was this new Zeta dropper post from KS. Previously spotted in prototype form, the short-travel, lightweight dropper has now made it to production for 2016. It features a unique cut-to-length design and should stir interest among the road and cyclocross crowds as well as with cross-country racers.

Retailing at £300 (international pricing TBC), the Zeta offers either 35mm or 50mm of drop controlled via a handlebar mount. The alloy post keeps its guts below the seat clamp and by doing so does a great job of hiding its adjustable ride height.

Up to 90mm of alloy can be removed from the zeta's trimmable shaft:

It’ll be sold in 30.9mm and 31.6mm versions and we are told that a 27.2mm version is also in the pipeline. The Zeta is also internally routed, so you’ll either need a dedicated frame or in some circumstances we’ve been told that routing for electronic groupsets can also be used.

Much like saddle height adjustment on many high-end road and TT frames, the clamp head of the Zeta can be removed and the post beneath the head can then be trimmed to a rider’s requirement – a full 90mm of material can be removed, and the black shaft is marked with 5mm increments ready for your careful cut. Its zero-offset head then simply bolts back on the trimmed tube.  Claimed weights stand at 462g and 530g for the 35/50mm models respectively.

The Zeta also does a pretty good job of not looking like a dropper, and at the moment it’s a fairly unique product. Think this is the start of a trend? Let us know in the comments below.

It's the most discrete dropper post we've seen to date:
