I don't think the gearing overlap with other bikes is an issue. You're likely to ride the same roads on the custom as the AHH; but on a lighter, unloaded bike; so the difference will be in the frame/tires/load. I long ago lost any romance for "road bike gearing" which made the hills around here too miserable to climb.
The one unanswerable are club rides, which can get competitive no matter how "casual" they're intended to be. I use a 46 big ring on my Appaloosa, but I only ride solo and feel no pressing need to make a fast descent faster by pedaling through the top gear. You'll need to do a mental checklist of how often you're pushing a close-to-top gear now on those club rides, then decide if you think dropping 4 teeth in front will keep you in the range needed. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
