I am 147lbs and 5'8" For me a noticeable diff between Bleriot/Sam, then a step up in ease of pedalling to Ram, then a dramatic step up to Roadeo. I can also confirm the diffs in mph and cog diffs in familiar terrain. Higher toothcounts front and back on Roadeo and getting up hills easier than with the other bikes. Though I am not obsessed with speed, but want a bike that moves easily as I pedal along and doesn't bog down on hills and make me feel like I am fighting the bike.
I am guessing the diff is in frame tubing because the Roadeo is definitely the more efficient bike, even with very similar Rivish build. Maybe chainstay length, too. Toshi is about same size as me and we ride same frame sizes. Perhaps our diffs are in fit measurements. Also, Toshi is a power Randonneur, so he can probably blast any bike down the road with ease. Where I am a weak rider and maybe can feel the diffs. I remember that BQ stated the most dramatic diffs felt in their tires are felt by weak/slow riders. Maybe the same for tubing diffs. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
