    Can I make 9-speed 105 shifters work with a 8 speed cassette?

    Can I make 9-speed 105 shifters work with a 8 speed cassette?

    Anyone know? I currently have a 2200 8 speed cassette and buying some 9-speed STI levers. Is there anyway I can get the shifters to work with this cassette or will I need a 9-speed cassette?

    Thanks alot guys!!

    No. The center-to-center spacing is different between 8 and 9 speed so the indexing will be off. You will get ghosts and mis-shifts. 9-speed cassettes aren't really all that expensive. I would suggest using one. You will also need a 9-speed chain as the widths are different.

    yes you can, by clamping the cable on the other side of the derailluers pinch bolt; thus exacting a different amount of cable pull similar to an 8sp shifter. then just play around with the barrell adjuster.
    or just get a cheap tiagra 9sp chain & cassette.

    Shimano compatible cassettes in 9 speed are SOOOOO CHEAP, it doesn't pay to fool around. Just sell the old 8 speed cassette on ebay to recoup some of the expense. Good luck

    OK sounds good. Thanks for the help! I found a guy selling a 105 9-seed cassette with 1000 miles on it for 20 bucks does that sound fair?

    Maybe, are the cogs the size that you need?

    Ya, that's okay if it's the right sized cassette! Nashbar sells Shimano-compatible 9-speed cassettes for about $20, also. They are durable and shift well for me.

    Shimano 9 speed has to be a "Best Buy" in components. It ain't pretty but it's cheap and works. That's all you can ask for. Good luck

    1000 miles isnt too much though? It wont be too wore? It seems to be in good shape. Here's a link to the pictures.

    Need opinions on some older 105 parts

    Thanks guys!

    No, 1000 miles is *normally* not too much. I'd expect a typical good-quality cassette to last 5-10,000 miles. But it depends a lot on how clean the rider kept the chain and in what conditions he rode.
