Video: Shredding the Gamux Gearbox DH Bike on Swiss Trails
We are not only designing our Bikes ourselves, we also go out and try to push them as hard as we can. True to the motto "we ride what we sell" we want to find confidence in your own designs. Join our head engineer as he sends the Sego down the trails on a mystical fall day.
"One more please!" - Closed lifts meant more hiking. But in true Gamux-fashion, the team got work done anyways, not shying away from a good challenge
Fall in the swiss alps - perfection! - The Sego was born in the Swiss Alps, providing epic landscapes and some of the best terrain to test a bike
Using swiss design and future-proof technology to provide bespoke riding characteristics, the Sego is built to go fast!
To find out more about the Sego, be sure to check our socials:

Big thanks to our partners who support us in our pursuit of performance - you rock!

Engineers have made suspension work with the drive train fitted.
Plus... All that weight in 2 place on the bike!
If it was "better", it would be faster and all the top dh bikes would use it, as they don't, we can only conclude based on the evidence that a gearbox is "not better".
Came to that conclusion based on my limited knowledge of engineering. Engineering these days is 95% paper work, 5% engineering!
I think in the future all top dh bikes will use a gearbox system
Just from the technical side a gearbox for DH would be the way to go. But if marketing and contracts with other companies don't allow it, it won't happen.
As for it being the future, the very small minority have been saying that for so many years.
But more to folk think the earth is flat!
Someone from a WC team once said .. I test more than some WC teams do. True story.

From the reviews that were out in the gearbox golden age just before 1x drivetrains came out when it looked like they were the future the biggest complaint seemed to be inability to shift under load, not so much a drop in efficiency. Everyone is drooling over high pivot bikes with idlers rn but they have a loss in efficiency too.
Right now, I'd get a gearbox bike for a fun ride everyday bike. Just not for an XC race bike.
I had a Balfa BB7 and the difference with a Hammerschmidt or a Nexus was huge.

They instead seemed to find that it was "fine" in the lowest gears and only dropped off significantly in the smallest rear sprockets, however they had aligned the front sprocket with the centre of the cassette which isn't typical and can leave the chain rubbing the next biggest sprocket when in the higher gears.
Problem with the Pinions and similar is the constant engagement of all the gears, so there are inherently going to be losses associated with each mesh and there is a mesh for every gear plus the working mesh from the lay shaft back to the concentric sprocket.
