Sorry for the sort of double post but I wanted to guage the STW massives thoughts on teh following:
Bought the Ultegra 7600 Groupset for a new build. Fitted it last night and finished this morning so I could ride it to work. Fab. However fitting the chain (7600 chain instructions say unidirectional) found the OEM chain to be supplied as a 6600 (old ultegra) and multidirectional.
Should I complain to Merlin or am I being picky (great bargin as cost me £525 in the end!) as I don't think it makes a lot of difference and i'll change the chain in 6 months to a 6700 probably anyway?
