3.9kg Berk Road Bike | Insane Lightweight Tech from Slovenia

Berk has built one of the world’s lightest road bikes that, unlike many featherweight bikes, gives up little in terms of usability. The Slovenian brand has exclusively shared details with BikeRadar on how it created this mind-blowing 3.9kg road bike.

The bike was intended as an in-house project to test the limits of what Berk can produce. The result is a sub-4kg bike that can be confidently ridden daily.

That last point is the key one – according to the Slovenian brand, it would be relatively easy to produce a considerably lighter bike but the brand’s mission is to build truly “lightweight yet reliable parts”.

Berk also wanted to illustrate that, while the rest of the industry has been focussed on advancements in aero and disc-brake technology, there are still significant advancements to be made, and public interest, in lightweight technology.

We can’t help but agree – aero may be fast but there’s little that stirs our weight weenie loins quite as much as the sight of a true featherweight build. Anyone who’s tuned in to BikeRadar’s Hill Climb Diaries will know as much.
