...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....
peace
and a very prosperous new year
