Schlumpf goes EU

Shortly before Eurobike 2011, we signed an agreement with German engineering company Haberstock Mobility GmbH.

Initially, assembly and service of the mountain-drive, speed-drive and high-speed-drive bicycle gearing systems will move to the German town of Lauchringen, close to the Swiss border in Southern Germany.

Under phase two of this agreement, all production will take place in Germany.

In part, this is a response to dramatic changes in the exchange rate of the Swiss currency, which have made exports into the EU and elsewhere as much as 35% more expensive over only a few months, without generating extra profit for the exporter.

But this move also reflects the fact that manufacturing and assembly capacities at the Schlumpf works in Vilters cannot be expanded beyond present capacity, which is needed to accommodate the growing popularity of Schlumpf gearing systems, especially in new applications such as E-bikes.

Last but not least, schlumpf innovations is an R&D company, and owner and CEO Florian Schlumpf looks forward to having more time in the future to develop new projects.

Founder and owner of Haberstock Mobility GmbH, Rolf Haberstock, is widely experienced in everything from prototyping to mass production for the automotive industry. He is an expert in automation and workflow rationalization, and has implemented sophisticated production methods in his own company.

Beginning 1 November 2011, assembly and service will take place at Lauchringen/Germany.

schlumpf innovations will dedicate its capacities to increased output of unicycle hubs and has plans for a worldwide distribution of its self-activated waterpumps (hydraulic ram), which is a part of the family tradition at Schlumpf since 1886.

An interesting article about belt and other drives in the New York Times:

Have you ever wondered what's inside a Schlumpf gearing system?

Do you have apprentices or students eager to learn about the latest innovations in bicycle technology?

We now offer an educational package that consists of a Schlumpf speed-drive cutaway model. This model is fully functional, able to shift and turn, while displaying every internal part down to the last screw.

"Yesterday we had the fantastic experience of trying your "Pieza de
ARTE", we are very surprised of the effectiveness of the speed drive,
not only thinking of competition but in the most important thing "The
daily basis" for the STRIDA foldingbike. For Barcelona & Girona is a
fantastic way of improving all the trip by bike.

Enrique"

speed-drive for Strida is available!
We deliver a version, that is ready for installation into the Strida folder.
Equipped with a special eccentric piece, you don't need to chamfer the bottom bracket nor use any special tools. Simply take off the old eccentric bottom bracket and insert the speed-drive into the frame.
Comes with a 80t. belt disk, that gives both lower and higher gears (80t. equals 132t. in high gear!).
Delivered with the correct belt length (HTD 1360).
Please notice: the internal parts were modified in order to correspond with the higher preload of the belt compared with a chain.

Always ask for the original Schlumpf speed-drive made in Switzerland!

Available at your Strida importer. Ask us for the nearest selling point.

EBB (eccentric bottom bracket)

From now on we offer the speed-drive also for eccentric bottom brackets.

It is designed for externally clamped bottom brackets.

Please inform us of the internal diameter of the bottom bracket shell and we machine the part to your requirements.

     
     
     
 

Cone rings with form locking by milled grooves

mountain-drive and high-speed-drive now come with a form locking contour on their backside, that gives high resistance against spinning under load.

The modular concept allows the use of just one hub for a couple of different applications.

The cone rings coming with milled grooves are available in steel (for aluminum bottom brackets) and aluminum (for steel b.b.'s).
