what gear inch range does it have?
did you ride it with the luggage weight that you think you'll be riding with on a long trip? and on hills on trails and whatnot?
What are your thoughts then from the ECR riding experience vis a vis gear inches you'd be comfortable with?
and hey, 15mph average is 24kph--which is really dam fast. I dont think Ive ever had an average that high on a bike tour, heck, not even on commutes and such because stops and gos, and times when we ride slow, always has brought my avg speed to 15, 16kph ish, maybe a bit more at times, and often times slower than that. On the Latin American trips, the aaverage speeds were often in the 12, 13, 14, 15kph range. Heck, even with my wife in France this summer, the average speeds were in the 15, 16kph range--so Ive always used this range of 16kph or 10mph as a good guesstimate of avg speed for planning days---BUT get into mountains and its going to be lower.
ps, I cant remember if you mentioned how you set up the troll--what bars? 10 speed, 11?
