It's thanks to this forum I found out about this adapter.
Originally I was looking at the older 11sp Record/ Super Record, bit prices are high for clean ones. Ended up shopping around for individual parts and saved quite alot on this one even though its all brand new.
Nice one. I found out about it from the guy who invented it at Bike Forums, and came in here pimping it for all I was worth; too many flexy old quill stems and skinny bars in MGOOF.
If you're gonna hotrod an old frame, I say bring all the performance improvements.
That's the only adapter that looks exactly like a threadless setup... Lovely bit of work.
Were you tempted to go with a slightly older groupset?
