I just picked up a secondhand bike in lovely condition from a guy down the road - an 80s Falcon Westminster light tourer. Components range from the good (531 frame, B17 saddle) to the OK (Rigida alloy rims) to the frankly a bit crap (Weinmann suicide brakes, Shimano SIS rear mech). I want this to become my longer-distance-soak-up-the-bumps day trip bike. It's not good enough IMO to warrant the vintage restoration approach, so I'm currently torn between: moderate upgrade - better vintage rear mech, bar end shifters, better brakes (the Weinmanns are awful, I almost missed by turning in the village!), new wheels, retain current 6 speed block complete drivetrain upgrade - STIs up front, maybe 105 in back. Done over time to spread cost. What does everyone think? The brake upgrade is a must - I will get some koolstops in the meantime, but I'm used to Vees and I'm not that nostalgic for sticking my foot in the spokes! What are my options regarding this? What is there in the way of decent brakes that will fit around 32mm tyres and attach to a steelie frame? And would they be compatible with STI brifters?
