I have a 105 11spd groupset for sale, all taken off a bike that had been ridden once I believe.
I already had a full SRAM gruppo sitting spare in the shed, and these days prefer SRAM anyway, so this is all surplus.
Shimano 105 5800 STI brifters
Shimano 105 5800 Rear Derailleur (med/long cage I believe)
Shimano 105 5800 Front Derailleur
Chainset RS500 50/34 Hollowtech 2
11-28 11spd cassette (SRAM)
Although I work in central London I haven’t been into Town since before lockdown as my employer has closed its offices. So happy to post, or it can be collected from near Horsham.
Just ask for more pics if you need them.
