...reckon what i'm learnin' is...that the 16" wheeled Agilities probably run a bit slower than the 12" due to the increase in mass...and i think there may be some final drive ratios that play into that...
...i like the styling of the RS and the City, but I sure ain wantin to sacrifice performance for style....
..i'm kinda pleased with my A50 as it runs right now...
...However, I'm
sure that you need something way less than 7 grams...
..dude, i'd start with 5 gram rollers, and according to your riding habits, and the general terrain that you run regularly,....maybe even lighter than that....
...granted, these recomendations are based on my own experience....
