mscalisi said:The thing that's a little disturbing to me is that a freewheel mode is
possible...With a freewheel UPD, you can come straight down. It's possible that
you fall slightly backwards.
I had a freewheel fall on the geared hub, first generation, a couple
years ago, right before Ken's fall broke his leg. In my case, I fell
completely flat backwards, landing like a snow angel. Luckily I had a
[censored] pack to protect my spine and a helmet; I always wear a helmet
with a guni at ANY speed.
As for Ken's Q about speed: I reached 21 mph as a max speed on my Coker
with 110s. Without a steepish hill, my cruising speed was no greater
than about 16 mph for an extended period. With my 29" guni and 125s, I
can reach 22.5 mph (35.6 kph) and was able to maintain 18 mph (just
under 30 kph) at RTL under the right circs. So I'd say that the 29"
guni added about 5-10% to my speeds without costing too much in work.
