Bike Check: Magura x Engadin Bike Giro

A racing bike with no lines and cables. Two of our MAGURA employees are tackling the 3-day Engadin Bike Giro stage race this weekend – and their racing bike is like a glimpse of the future! A look at the MCi concept bike.

Integration is the driver behind many new developments. Batteries are invisibly integrated into the frames of e-bikes, shock absorbers move inside the frame (see Scott Spark) and handlebar and stem unit combinations have been cleverly concealing cables and wires on racing bikes for a long time now.

MAGURA Cockpit Integration (MCi) takes the topic of integration to the next level. For the first time, the new MAGURA MCi relocates the hydraulic unit of the brakes and all lines inside a flat bar. The result is a tidy look that goes hand-in-hand with a functional improvement and provides effective protection against falls and mechanical damage.

This development is much more than just a design gimmick, and two of our employees will be showing that the development is 100% race ready by participating in the prestigious Engadin Bike Giro stage race. Both will be racing with the MCi hardtail concept bike.

Internal cylinder

The heart of the MAGURA MCi is a cylinder, which is invisibly located in the handlebar grip area. The brake lines are also laid inside the handlebar – they are led through the stem unit and steering tube through special holes in the handlebars.

The dimensions of the expansion reservoir and the piston diameter of the MCi correspond to the dimensions used in the MAGURA MT series. This gives the MCi the same stability and braking force as conventional MAGURA MT brakes.

For the brake callipers, our racers will be relying on the 2-piston versions of the MT8. However the MCi could also be used with 4-piston callipers, depending on the usage scenario. A mix of 180/160 mm is used for the rotors. The larger rotor at the front is only slightly heavier, but it provides solid stability for the long descents, some of which fall 1000 metres in altitude. The riders weigh 67 kg, and this combination on the CC bike is sufficient for that weight.

Hidden tubings

Starting from the MCi cylinder inside the handlebars, the completely invisible tubings run through the handlebars and stem unit. The front tubing then goes through a prepared hole in the stem unit directly to the line routing at the suspension fork and to the brake calliper. The rear wheel tubing is led through the headset system into the frame. The diameter of the upper headset bearing is oversized to enable the guiding of the tubing between the tapered steerer tube and the bearing. A reducing sleeve provides a guide hole for the tubing – an invisible entry into the frame. This type of routing is already available in serial production from some headset and bicycle manufacturers.

User-friendly Easy Link installation

The new MAGURA Easy Link tube coupling enables a simple plug-in connection between the MCi and the brake line. During servicing, the entire unit can be separated and dismantled without losing any oil.

VYRON dropper seatpost:

Due to the demanding trails in Switzerland, both of our racers will be relying on an adjustable VYRON seatpost with 100 mm travel. The wireless system not only improves the look and facilitates installation, but it also allows fast replacement for the less technically demanding races. For marathons with no heavy trails, for example, the seatpost can be replaced with an ultra-light carbon model in just a few minutes.

Other components:

The weight is also optimized down to the last gram, something that’s typical for CC bikes. At 6300 metres of altitude spread over 3 days, the Engadin Bike Giro certainly involves a lot of uphill climbing. We rely on Rotor crank sets and DT Swiss wheels equipped with Schwalbe tyres. The lightweight MCi carbon handlebar was developed by BikeAhead. The contact points to the bike are by ergonomics specialist SQlab and the frame was developed by Arc8 Bicycles.

Initially, the MCi will only be reserved for OE partners. MAGURA will act as the MCi system supplier during the development and will specify the components such as handlebars, stem unit and cable/line routing together with the respective bicycle manufacturer. An aftermarket version is not planned for the near future.
