Ye Balde One, did you have the AX hubs with all the spokes coming from the outside of the hub? Now that was a pain in the neck if you broke a spoke!
I'm rathur envious that you have a pair of Molodo Kronos brakes, they wre seriously light, bit scary though.... Did you ever have the pleasue of the wonderful downtube shifter coming off in your hand?
I used to have those hubs, never had any problems with spoke breakage so I can't say, but building them sure was fun.
I once tried using Kronos on a road bike, until down a descent BOTH cables pulled through the clamp screws, which made me even more wary of the Cat-Claws, their screws were the same size. I destroyed a pair of Vittoria shoes that day just slowing down enough to make a hairpin bend.
I have a set of the levers NIB, but I never used them back in the day, I used Simplex retrofriction all the time but for my Dura Ace AX bike until the New Dura Ace came out in 1986.
