I have just bought a Pinnacle Evolution 1, feels like a good bike and something that could last me for quite some time (better than my Halfords special did anyway!).
My question is how easy is it to upgrade (over-time) to a better spec, and would I really feel the difference?
At the moment it has a set of Deore Derailleurs (3 front and 9 back). How easy would it be at some point in the future to switch to the XT variants, and would it really make a difference? (could I do this myself).
Also, what other things are easy to upgrade that would give me a better ride/feel?
I commute 20 miles a day so I have switched to a nice set of road tires on this.
