Someone is selling a Birdy Touring (ie. with the SRAM DD3-24) and Magura hydraulic brakes.

Before giving it a try, I'd like to know what you guys think about those two features. Since this bike will mostly be used for touring, I'm concerned about the reliability + drag of the IGH, and of using hydraulic brakes on a folding bike.

As an alternative, I could get the 2015 City and replace its Shimano Nexus 8 IGH with an an Alfine 11 for a wider development range.

Thank you.
