Vecnum claims moveLOC XC is the world's lightest dropper post

Dropper boasts 100mm of travel, external routing and excellent compatibility at just 380g

German brand Vecnum just sent us through details about its new moveLOC XC dropper seatpost, which at 380g (claimed, not inc' remote) makes it the lightest dropper seatpost on the market.

As the moveLOC is a cross-country oriented product it is available in a 100mm travel version only.

The externally routed seatpost only comes in 30.9mm, but can be shipped with shims for larger seat tubes.

The lower part of the moveLOC can be shortened by up to 40mm, and not only will this drop a tiny bit of weight, but it will also improve compatibility with some bikes — particularly smaller sized frames or those that have a seat tube that is interrupted by a bend or suspension pivot.

The seatpost will be available with either a regular remote or a trigger style one — the imaginatively named TrigLOC trigger remote weighs a mere 17g, which Vecnum claims makes it “the lightest trigger style remote on the market.” Both remotes are made of 7075 alloy.

The head of the seatpost is forged from 7075 alloy, and, critically for the notoriously weight-conscious XC crowd, it is compatible with oval carbon rails. Everything is cinched down with two titanium bolts.

For those concerned about reliability — I’m thinking long-distance XC marathon racers in particular — you will be happy to hear that the moveLOC XC has a ‘fail-safe-button’ that allows you to “lock the post at any time in any position”.

The post is available for €369 direct from Vecnum. International pricing is TBC, but worldwide shipping is available.

Does a dropper make sense for XC racing?

With courses getting more technical and bikes more capable, it makes a certain amount of sense to take full advantage of the extra control a dropper affords you, but is it worth the increase in weight?

Joe Norledge did some testing with dropper posts for XC racing last summer and you can see the results in the video below.
