PowerDesign - HSi - the new generation of MAGURA HS

Bad Urach, (lifePR) - As the first hydraulic rim brake, the MAGURA HS revolutionized cycling 30 years ago. Over the years the HS-brake won numerous tests for its reliability and braking power. These days the HS is a synonym for durability, stress-free and safe braking on bicycles. Even the rise of disc brakes for bicycles didn't affect its success.

The trust of dealers and customers in the HS33 R, HS22 and HS11-brakes motivated the MAGURA developers to use the HS series as the foundation for a new project.

In cooperation with bicycle manufacturer ZEG and suspension producer SR SUNTOUR the engineers and designers for the first time developed an in fork and frame integrated version of the MAGURA HS. ZEG is going to mount the brake on both, E- and regular bikes of their brands Hercules, Pegasus and Wanderer.

Goal of the integration project was besides an exciting new way of design, the improvement of several other features.

• Easy handling while wheel changing
• Tool free brake adjustment
• Simple brake pad change
• Improved ridgidity, therefore increased braking power, especially on the back wheel
• Easy service and maintenance for bike shops and industry

Interview with MAGURA product manager Martin Schneider:

Which model was used as the foundation for the HS integral?

ZEG decided to use the HS22, but the HSi works with every lever, if there is requirement to change.

How complicated was it to integrate the brake into frame and fork?

It was actually quite complex, just the development took 1½ years and that does not include the design process. The success is based on the close partnership between all three companies thoughout the project.

Is the HS integral equipped fork by SR Suntour going to be available for other brands too?

In its first year the brakes and the fork are exclusively delivered to ZEG. From 2019 on, the system, including fork and brakes, is going to be available for other brands too.

Which benefits does the rider have?

On the one side, the brake is visually integrated into the bike, on the other side we were able to increase the overall performance of the brake. The increased stiffness results in a more defined pressure point. Due to that, the braking distance shrinks and safety while riding increases.

What's the difference between a regular HS brake and the HSi?

The entire mounting on fork and frame was redesigned, now the fixation doesn't require the "canti-bolt" anymore, it works easily through a clamp.

Have you been able to save some weight with that?

Yes, 50g per brake. (For example the HS22 currently weights 440g, the HS22i only 390g)

How did the handling for the customer change - or improve?

The quick-release skewer got an update and therefore was ergonomically a lot more comfortable. You'll also require less strength to open it.

Are the HS spare parts usable on the HSi?

All the components, except the HSi mounting parts, remained the same, so you can use all the spare parts.

Where do I get spare parts?

Either through us or ZEG directly.

What needs to be checked while mounting?

Like with all of the other HS brakes, it's important, that the quick-release skewer is closed in an orderly fashion and that the brake pads are in the right position to the rim.

How did you achieve the clearly increased pressure point on the back wheel?

Due to the construction of the new HSi brake, the frame get 2,5cm closer to the actual brake, than it usually is on the regular HS brakes. You can see that visually, plus you can obviously feel it while pulling the lever.

What kind of adjustment possibilities does the HSi have?

With the MAGURA HS22i you can adjust the brake pads once they start wearing out, besides that the lever is adjustable in three reach positions.

Are there different kind of brake pads?

Depending on usage and preference, all of the HS brake pads options can be used.

Off the shelf the brakes will be equipped with the black standard pads.
