WTB: Cheap parts for a turbo build

As per title, putting together a bike to stay on the turbo, currently looking for these parts:

• 170/172.5mm crankset, 24mm axle, 1x or 2x, 10/11s compatible. (Square tapered also works)
  
• BBR60, needs to spin, used one is fine. (Square tapered also works)
  
• Bullhorn bars 25.4mm clamp 40/42 wide
  
• 11s RD, shimano/sram
  
• 11s shimano cassette and chain
  
  

Ideally located central or NE London

Think I've got a fairly lightly used KMC X11 chain you can have mate. Not sure how many links are on it, probably 112 or so. Potentially an 11-28 cassette too but need to check the spares box.

Think I might have a 6800 era RD in the parts box - let me have a look.

(Prob also got a cassette as well if amac90 doesn't).

Actually think I've got a 6800 chainset too....

Interested in RD and Chainset, let me know when you get a chance to check if you have them.. RDs are sneaky, I too thought I had one in the parts box, but seems to be gone!

Rd is definitely available, a bit scratched but assumed that’s fine for a turbo bike.

Chainset is in some boxes and I’m moving house so won’t be able to confirm for a couple of days - I’m sure it’s there, just need to check condition etc!

just an idea but i have an old carbon TT cockpit ( bullhorns + extensions ) which is quite nice for this purpose, changing position etc.

Yeah, that's where it might evolve to, starting with bullhorns, then adding extensions in the future.. (good for the towel too!)

I'd be also looking for a friction shifter ideally bar end one
