1)Counted 9 on the new cassette
2)Shifter model: ST-5600, 10 speed
3)Well partially my fault for not bringing it to a bike shop carrying the brand.
The same parts are used on all makes of bikes. Any competent mechanic at any competent shop should be able to help you out, regardless of the brands of iron that they push.
You are not at fault for taking the bike to a shop that you trusted to work on your bike.
You should have known how many speeds your bike has, and you should have been able to speak competently about the problem with the mechanic.
But I'd put this screwup squarely in the hands of the shop. They should have know better, regardless of what you know. Afterall, they are supposed to be the "professionals".
