    8 speed cassette to 10 speed cassette

    I have a bike with shimano 8 speed cassette and shimano 105 parts, I wondered if I could upgrade this to ten speed components(or 9 even) without changing the frame
    many thanks

    You frame is fine. All Shimano rear hubs from 8-10 speed are 130mm rear spacing so no problem. You can also use your rear wheel with a 10 speed cassette. Front derailleur is most likely okay but you will need new shifters and maybe, a new rear derailleur (I'm not sure).
    Becareful buying/selling bike parts on-line. I learned the hard way. :(

    Wheel might need re-dishing after moving a washer from the left to right side. Otherwise, no changes needed on the frame. I've spread a couple of steel frames to 135mm OLD as used on MTBs to reduce the wheel dish.

    Unless you have a 7- or 8-speed Dura-Ace derailleur, it will work without problems on your new 10-speed setup. And contrary to what the sales people say, your "8-speed" cranks will also work.
