I think after next payday I can probably afford a small upgrade to the commuter. I'm thinking of either bottom bracket, cranks and chainset (all cheap suntour at the moment) or a new rear wheel and cassette (basic machine built alloy wheel with 7sp cassette, a bit heavy but seems to roll okay).
Which is probably the better upgrade - I think they'll be a similar price?
My thoughts are the chainset/bb. I was thinking of Shimano Deore (any better ideas at a similar price, or good reasons for going higher). Should I go for the new octalink(sp) spline? Any advantages?
If I go for the wheel, what bits?
