Hi, just an update on my Perthus. I have had to put my Brooks saddle on it just for comfort reasons and I also managed to get some 105 indexed downtube levers from this forum. I have replaced the 105 chain set with a Gipiemme one, I much prefer the silver alloy look.
Finally I found out that the rear axle on the 105 hub was bent so I had to look around for the best option for getting a new one or replacing the wheel. In the end I found a pair of wheels with Campagnolo Record hubs and Mavic CXP 10 rims. I think they look better being silver instead of the dark grey of my old rims.
