Forgive my bike mechanic naivety.
It was the end of the century when I was last riding regularly and even then hills were always the enemy. I'm no whippet at 92k (but not blubber) so I always used to try and power up them then ease up a bit. Well that all worked for a while but as the miles went on it became somewhat harder and eventually something really nasty could have me on my feet.
So, here I am, a month back in and think I need a change of approach. The mechanical world seems to have moved on from my mid 90's Campag 9 speed (Chorus) with 52/42 rings 13-26 cassette.
What I'd like to achieve are some lower gears to avoid the prospect of being a bike pusher and I see that 52/36 and 50/34 are now available but they all seem to be 10/11 speed.
I've done a lot of reading but am still confused. The question is what do I need to change? Will I end up changing everything from b bracket, chainset, chain, cassette, rear mech and shifters or is there a simple route that I can't see for looking.
Whatever I do the cassette has to remain campag as I've just got a Powertap.
I don't have to do it myself as LBS are understanding that they cant compete with internet prices on components and are happy to do the work at suitable remuneration.
