M5 Ligfietsen Brakes
Super light brakes and beautiful German engineering.
Came top in April 2012 `TOUR` magazine of all the best lightweight brake sets.
Only 191g for brakes and shoes!
Very rare and well over £350 new.
Sold complete (i.e. with all spare parts and tools not pictured - barrel adjusters, different length threads and bosses etc.)
Barely used - my local bike shop thought that they were new!
