My brother in law is starting on a build he's just received a vintage Joe Waugh 531 frameset.The rear dropout spacing is 130mm,but may have originally been built as 126mm.He intends to install a new 11 speed Centaur groupset are there any problems he may encounter running 11 speed on a vintage frame even with the rear spacing at 130mm?The dropouts are of the horizontal type with axle adjuster screws,by the way.
Thanks in advance.
