Just a quick explanation, I am looking to buy a rear wheel for my road bike because I just got myself a trainer & I would like to use my current rear wheel for spin training (put on some durable tyres) and get a new rear wheel for outdoor use.
So i've been looking around for a rear wheel and i've got a few options.
One of the options available is a clincher HED carbon rear wheel: 700C with a 10-speed cassette (it says 13-25 & i'm not sure what that means).
My question is one of compatibility.
I've got a Giant TCR Aero 2 road bike with the following specs:
Shimano Tiagra 9-speed rear derailleur
SRAM 12-26 9-speed Cassette
'08 Fuji Roubaix RC; '07 Schwinn Le Tour GS; '92 Diamond Back Ascent EX
You'll need to swap the cassette out for a 9 speed to work properly. The 13 - 25 is regarding the range of teeth the cassette has. As you only plan to use the original wheel on the trainer, you might get by with the 10 speed cassette on the trainer wheel (just swap cassettes between the 2 wheels). It won't shift great but you will probably be able to find a few gears that will work. If not, just get a cheap 9 speed cassette for the trainer wheel.
A Tiagra quality cassette will generally cost $30-$35. You will need different brake pads, I'd suggest KoolStop olive or SwissStop yellow pads so that you can easily see if you have the correct pads installed.
