I don't know at what speed your hub generator won't light your light, but with a bike with high wheel flop you would probably notice wandering and the tendency to dart unpredictably from side to side at 4 mph climbing a 12% grade in a gear in the low 20s. On the same grade I think you would be hard pressed to walk at 2 mph on that same grade, and maybe when you got done smacking your ankle against the pedal, etc., might end up averaging something like 1.5 mph. At least, that's been my experience. > I can see how a heavily loaded front end might cause wheel flop going > super slow and for a front load only 'Rando rider' that might not be > ideal.....

The adaptations you mention will in all probably mitigate the condition. However, you can still be surprised even with little to no load: I recall climbing one 14% grade with no more than 3 lb load, all in a Carradice, on my Rambouillet when after having to constantly wiggle the bars to keep the bike going straight against its tendency to veer sideways, the bike suddenly went left at 90 degrees, straight across the road. I managed to stop and dismount before going off the left shoulder, and fortunately it was a very lightly trafficked road, so no oncoming cars. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
