My old birdy was an original Birdy Blue (3x7 sachs dual drive - pre-Sram), and the rear brake routing on the early models left lots to be desired which promoted the Magura's in the first place, that model also had simple metal oval loops to route all the cables so there were no cable bosses to drill out for the hoses, and because maguras can pivot through a wide range of angles and have fairly short blocks they actually fitted easier than the V's they replaced.


The front was a similar story, and was basically an external run of the way the hoses run today on the current model, although from memory it was on the Left hand leg not the right hand leg. Basically the hose ran down the left hand leg via cable ties, then I used a cable tie through the hollow pivot bolt to create a tight-ish guide loop to allow enough freedom in the fork fold but to keep it out of the way in normal riding. I used hope braided hoses rather than the black oem magura ones, and after about 4 years all that had worn from rubbing during folding and transport was the clear outer. The braiding was untouched.


Magura's are amazing brakes - nearest you will get to discs with a rim brake.


Hope this helps!
I've now replaced the front brake with an HS22 (will sort out the rear tomorrow). The cable/hose routing was much easier than I anticipated and I was delighted to find that the latest design of the booster mounting plate will fit without fouling the suspension. Just took it out for a test drive -- immensely satisfying: like night and day! Thanks for your encouragement.

I was all set to post a picture of the installation but apparently the forum won't let me post one until I've submitted 10 posts. :-|
