Hi to all of you Cycleologists out there. I have just over-come an issue with limited selection of gear ratios and a shift from 7spd to 8spd - without changing the wheel.
What I am interested in knowing is - is it possible with early Campagnolo hubs? I.E. Individual sprockets with appropriate spacers.
I have recently rebuilt a Benotto Modelo 850 :- My latest acquisition - an as-yet unknown 52cm (20.5") Benotto.
Since building and fettling the bike I have wanted to explore the possibility of further improvements around the Campagnolo Nuovo Gran Sport rear dérailleur and the potential for alternative sprockets/cassettes/screw-ons.
With that in mind I resurrected a tidy old pair of wheels that had seen very little use :-
I have just utilised a rather tidy pair of Mavic 195 rims with Shimano Exage QR hubs and the rear hub is a 7spd.
It now has 8 individual sprockets on it as :- 12:13:15:17:19:21:23:25.
I really wanted to retain the Campagnolo Nuovo
This wheel-set is going to replace a brand new pair of Weinmann XR18's (bought new and specifically for the rebuild) but with a Miche 7spd screw-on as :- 13:15:17:19:21:23:25.
The main reason for this change is to use a 125mm axle instead of the 130mm axle needed for the 7spd screw-on. The bike was originally built with as a 6spd (very limited spread) but the 7spd gave a better selection and now the 8spd conversion has been a really worthwhile further improvement.
