Today I went for a 22 mile ride with this bike. An organized ride of guys on carbon frame road bikes came by halfway through, and I was actually able to keep up with them, thanks to drafting. No thanks to the fact that I keep spinning out on downhills. I wish this bike was geared a little higher. The bottom chain ring is really low, the top isn't really high enough.
The smallest cog is 14 teeth. The biggest chain ring is 48 teeth, the middle one is 38 teeth. The wheels are 26".
What would be the most cost-effective way to gear it up- new chain rings, move the front derailer up, and install a longer chain for the bigger rings?
