I've seen there are rear derailleurs from the Far East which appear to be copies of the P-line item - I view them with some scepticism. Has anyone here fitted a 'regular' derailleur to a Brompton? I'm asking this because the jockey wheels on my 2007 (but less than 300 miles) superlight give the impression they are fragile After just 20 miles of being caught in the rain a couple of weeks ago I had to clean and lube them. Even thogh a standard derailleur may be positioned a bit lower I imagine the jockey wheels will be more durable. I offered up a Shimano Acera mech from my spares, and suspect it would fit the bill if used with an old style bolt-on hanger in place of the Brompton tensioner. In use (especially with close-ratio sprockets on my 2 speed (now 3). the cage will be almost horizontal and pointing forward, when folded it should point rearward. There are 2 snags I've seen though ...... the tension seems a lot higher than the B tensioner and more seriously it looks like the mech will clash with the front wheel upon folding. I wonder if a Shimano shadow type or Sram will be slimmer?
