Dear all, I'm having trouble wiht my rear brakes. They need adjustment at least once a week. The problem is uneven wear. The pad side closest to the seat...

Dear Piers, I haven't seen this problem on my Birdy's. I have models both with V-Brakes and Caliper Brakes. We haven't had any "uneven wear" complaints here...
I haven't tried a Schlumph drive, but I have been using my Rohloff hub for nearly a year in all conditions, the advantages are clear:- No mech hanging miles...
I just wonder if Schlumpf speed gear (mountain gear is unsuitable due to strict restrictions by Rohloff according to Schlumpf data) is added to Rohloff what...
I don't know, but talking about overkill, how about mounting the Rohloff and the Schlumpf on a birdy black. You could get 252 gears (14x2x9). The should...

Hi Carsten, It is a bit hard for me understand. Does it mean that a Rohloff and a Schlumpf mountain-drive are combinable now? What is the Mountain-Drive 8-O?...
Hello, I bought a "new" 1999 Birdy and it has the seat tube problem I once saw on this list. The problem is that the seat tube will not collapse quickly. I...
Carl, Try inserting the seat/tube UPSIDE DOWN (e.g., from the bottom towards the top) to see if the collar at the top of the seat tube is where it's binding....
... Thanks Bob, That was a good test. Actually the seat tube starts to bind only after it is in the frame collar six inches or so. And it does the same thing...
... Put some chain lube on some paper kitchen roll, and wipe the seat post. This does two things: it tends to remove any grime, and it leave enough lube to...
I have an anodised aluminium Birdy, a few years old. The unfolded rear wheel is meant to be kept in the unfolded position by a plastic catch that hooks onto a...

Simple - you just adjust its position. From experience the catch will be set a little too far forwards. Loosen off its allen key bolts, shift it to a better,...

Price of a Rohloff Birdy is even higher (about $300) than normal (2500 Euro) in the U.S. because since it is not directly imported from Taiwan, the U.S....
Carl, I think normally the seat posts as manufactured are good, round, straight tubes. They are anodised so they should not scratch (or polish) easily. The ...
