No decals! I personally am not big on stickers all over things. If anyone fails to be impressed because of the lack of stickers, so be it. Those in the know will appreciate the frame for what it is. It's also a flam finish, so it's enamelled silver, then with 5 coats of blue tinted lacquer to give a deep shine - it's the kind of thing done on hotrods. You wouldn't want to hide that under stickers
The HS11s had bigger moto-style levers and a fiddly allen key adjuster. HS33 had a different (larger?) master cylinder, which gave even more leverage, and smaller levers with thumb adjusters. Racelines have a different cylinder arrangement again I think.
HS22 I think has been used twice - I have some very old HS22's which look just like the HS11.
I'm a bit of a Magura addict - I have a set of the rare drop bar ones on my tourer, and two Magura-equipped tandems.
Ride it or milk it!
