In developing the new Birdy, we have looked at every single detail again. We have made nearly 100 improvements
And still no carriage block on the front
Hydraulic disc brakes now come as standard on all models. […] The new Birdy comes in four models with a wide range of accessories. Basically there are four models: the Birdy city, the Birdy dualdrive, the Birdy speed and the Birdy rohloff. The World Birdy remains available unchanged.
+1 for the disc brakes. I'm curious at the prices, though.
