Complete set of TRP Spyre post mount calipers with barely used Shimano resin pads. £40 posted in the UK.
For info TRP recommend 2.3mm rotors for tandem use. And compressionless cables also help with stopping power.
Yes, the outer cable will move (up) when you pull the shifter lever to shift the chain down into the inner ring. So when setting up just make sure there is enough cable outer to allow this movement. You don’t unhook the spring to set it, the neutral/slack/starting position for the mech is in the...

Not 531 but I have this early 1980s Raleigh Corsa I started but haven’t finished. 24.5” frame, 501 tubing, original paint in reasonable condition. I’ve already stripped it down so it’s available as a frameset only if that’s of interest too. I’m afraid I’ve already polished up the Golden Arrow...
