It feels nice, very light, strong and looks cool.
The dropouts prevent the chain from coming loose and they are different to the ordinary horizontal dropouts.
The BB is a wierd size and it is very difficult to get the bearings in, they dont go all the way in and sort of stick out a little bit, still works fine though. The dropouts cause weird chain tension, you can either run it close to snapping and killing your sprocket or quite loose and scratching the frame bit of a pain in the arse but small price to pay for such a good frame. Back end length is kind of wierd for manuals, might just be me though.
