The Hub – Southampton.
Guys in there especially mechanic couldn't have been more helpful when I was building my Epic.
Advice, bit of tinkering, fitting BB, and only charged me 27.00 to go over complete bike, rectify all my mistakes, fit chain, swap cables, sort out brakes, adjust mechs etc.
Only bought a few odds and sods along the way so was not as if I was spending 100's of pounds.
Cant praise them enough.
