So I've boght a pair of those with a 8 spd cassette.. problem is I found a good 9 speed chorus equipped
bike on ebay italy and got it. So, is there any "cheap" way to get a 9 speed cassette on the Vento? I know about the Corima freewheel but its quite pricey at around $100 for just the freewheel hub + another cassette.
Thanks for any help!
