[MENTION=315073]The_Joe[/MENTION], yes! That's the beauty of this approach, is that you can fine-tune the gearing that you want. Say you like really tight gearing and just need a bailout for the occasional tough hill. You could set this up as a 13-15-16-17-18-20-24-28, 8 speed. I'd use a 9 speed chain. In order to fine tune to the exact gearing you might need to purchase two 9 speed cassettes, possibly a SRAM 12-25 and an 11-28. Best of luck with your project.
