135 mm BCD is correct. The Specialities TA "Vento" rings fit and work perfectly and are seriously beautiful (if a chainring can be described as such).

Source TA rings at Peter White Cycles in US, Spa Cycles in UK, or SJSCycles in UK. The actual TA website is a bit hard to follow and prices are steep.
