Talking with the owner at the LBS, I was telling him that I had my bike with old 105 Shimano and even a Shimano 600 rear deraileur. I told him I don't ride that much but over the years km accumulate and that they are in perfect working order, I check the chain and have replaced it a couple of times, I always lubricate it.
He told me that Shimano is much less durable than Campagnolo or SRAM, he says that the way he rides that Shimano won't last more than a year or two. I find it hard to believe but his the experienced and is supposed to know what he is talking about.
I' about to replace the old 105 8 speed for a new Ultegra ten speed just for renewing not for any other reason, as I said the 105 is still working with no problems. I will replace the shifters, chain and cassette. If necesary the rear deraileur but I'm almost sure it won't be necesary. I'll keep the old 105 crank and FD. Campagnolo and SRAM are too expensive for what I think is not a big difference in performance, specially Shimano vs SRAM, to me Campy really is above of the other two but I don't or can't spend that much.
