if you look closely you will notice that Jan even used the carbon fiber brake blade in his conversion. this requires even further modification.
looking back on things it would have been much more economical to buy a set of silver chorus/daytona 10spd levers or even NOS 2010 centaur ultra shift levers from the UK. i mainly did it because i was always jealous of Jan's levers. i believe marco rode a set for a short time as well.
