As suggested by tcs at another thread I'd like to ask here for some details of the new Curl i3.
Thanks to the brilliant pictures at Thor's page and kind help of the German "Faltradforum" members there are some things clear already, like the cable routing. As you can see below is the routing of both (shifting and brake) cables pretty different to that of the two smaller pics.
At the right side the switching cable is touching the teeth of the chainwheel - it will get caught between chain and teeth sooner or later.
The brake cable at the left side does interfere with the crank, too, because the frame eyelet is at the right side and can not be used to guide the brake hose as scheduled.

The improper cable routing was caused partially by using a different, mirrored caliper (to that of Thor's Curl and many others) and using the wrong route (respectively wrong cable tie fixing point) for the shifting cable.

Detail:
At Thor's Curl (fifth image) one can see a writing at the caliper "Tektro R357" - there is no writing at our caliper and it is mirrored (cable attachment at the left side and not right).

Question:
Can anybody please tell me where to order exactly these Tektro R357 calipers?
