Dropper seat posts have been one of the biggest advancements in mountain biking in the past few years and this kickstarter from Spain is hoping to bring about a similar revolution with its dropper stem.

The 3FStech AIM (Adjustment in Motion) is a three position dropper stem that allows you to change your riding position on the bike depending on the terrain you are riding. The bar clamp slides along a rail that changes the height and angle of your stem between positions.

The climb position has a length of 120 mm and an angle of minus 20 degrees, this should bring your weight forward over the front wheel while ascending. The downhill mode has a length of 55 mm with an angle of plus six degrees will put you backwards for tackling steep descents. There is also an intermediate trail mode with a 95mm length and minus seven degrees angle.

The stem is activated using a remote on the bar and it can be used while you’re on the move, although we wouldn’t fancy giving it a go over anything too technical!

The stem and remote in combination weigh 400 grams (at least double what a normal stem would weigh) and 3FStech only produces 1 1/8th inch steerer clamps at this time.

The Kickstarter is hoping to raise 25,000 Euros (£18,000) in funding and currently has one backer with 44 days to go.

On the Kickstarter it will cost 175 Euros (£126) for one stem with a claimed normal retail price of 275 Euros (£200). 3FStech is hoping to ship the stems in January or February of next year.

What do you think? Are these the seeds of a great idea or another fad that will fall by the wayside?
