I took my kinesis bike to my LBS today as I thought after 7000 miles the rims were looking a little tired. I was advised the best way to go was buy new wheels....is this correct is it cheaper to change the wheels than rims? I am not very technical minded so advice would be welcome. The groupset is campag veloce and it is a 10 speed cog set on the rear. If you buy better wheels do the rims last longer? is 7000 miles a good average? Also I presume if I had paid more attention to the rims and cleaned them (which I did not do when I cleaned the rest of the bike) then they would have lasted much longer. I presume the same goes for brake pads...if I had used for example koolstop salmon (which I have just ordered now) then presumably the rims might have got me to 10000 miles...questions questions so many questions....what do you think? thanks as always

Ive put an old set of wheels on the turbo bike; there's no way I'd trust those dodgy rims on road but with un-shipped brakes they are still going.
, it's always the bearings that fail first...
