One of our favourite Instagram accounts is The European Bike Project because the page is continuously updated with content ranging from insider looks into European manufacturing to posts from teeny makers. Alex is seeking out the most intriguing items from small manufacturers for you at Eurobike 2023.
Since we originally discussed the 612 disc brake more than a year ago, a lot has changed. The brake now goes by the name “Die Bremse” (literally, “the brake”) and has a completely new appearance.
Die Bremse has been available from Felix, the man behind 612 Parts, for a few months now. The Cybertruck-like design stands out from every other product on the market in terms of appearance. The master cylinder has a 9 mm piston and PTFE seals, while the brake calliper has four stainless steel pistons (16 and 17 mm in diameter). Standard brake lines or a steel braided option are both options; both types of brakes use mineral oil.
All machined parts for Radoxx are produced in Germany using 7075 aluminium. Other countries also supply a few tiny parts, but Felix assembles all the brakes in Switzerland.
The German business Unger Kabel-Konfektionstechnik GmbH, which specialises in electric cables, automotive equipment, and sensors, owns U-micro Mobility. Experts in brakes will note that the TS4 is based on the “Bees brake,” a concept that was developed about 15 years ago but was never widely adopted.
The four 19 mm pistons of the TS4 are. A mechanism that actively pushes the pistons back into the brake calliper is being developed by U-Micro Mobility. The foundation of this technology is a somewhat hollow piston and a little spring that forces the piston back, ensuring that even when you’re merely riding and not applying the brakes, the pads will never contact the disc.
The brake levers include a large adjustment that allows you to modify the bite point and retract the pistons while changing brake pads.
Unger is equipped with the necessary equipment to manufacture these brakes in-house, including a test facility. The brakes are currently being tested, and they intend to market them to OEM and aftermarket customers.
Formula had their Cura X at the show, which come with carbon levers, braided hoses, two 24 mm pistons and titanium screws. The Cura X is 34 g lighter than the regular Cura. A full system with a Cura X, 160 mm one-piece Formula rotor, and all mounting hardware weighs in at 325 g.
Formula’s new two-piece lever features their FCS technolgy (Feeling Control System) and tool-free reach adjustment, so you can fine-tune the feel and braking power.
Currently, Trickstuff is investigating novel techniques for producing brake levers. As seen in the photograph, they could be partially hollow in some areas.
Trickstuff’s booth was extremely crowded because of all the fascinating 3D printed parts that they had on display, even though they did not introduce any new DH brakes or other exciting products. They collaborated with 3D printing experts Trumpf to investigate the feasibility of printing brake devices, among other things.
Magura had a new system for cargo bikes at the show that will activate both calipers even if you only pull one lever. This idea might also be useful for adaptive bikes, but we likely won’t see this on traditional mountain bikes anytime soon.
Apart from the new MTA2 allround brake, they also had this Demo with an extremely subtle paintjob at their stand – just look at it!
