He said it's on 80 mm cranks. Surely it's fast, but well possible.
I have sustained 9 mph for a minute repeatedly, and that was with 125
mm cranks. The cadence is then 163 rpm. (This was a measured road
speed, with 3.6% inferred wobble percentage.) With 'just' 182 rpm, you
go 10 mph.
Hmmm, ok. Maybe my calculations are a bit off - I was working it out
from a measured cadence (160rpm - don't have any way of measuring road
speed atm), and turns out my "cruising speed" should have been 9.5mph,
rather than the 10.5 I thought, and that's assuming my wheel diameter
really is 20" (I'm riding a Primo Wall 20*2.1, fwiw). And that my
wobble percentage is 0%, but I don't think I lose much except at really
extreme speeds or downhill....
So my road speed is probably rather less impressive; hence asking, how
fast should I be able to go? :-).
The (sustained) 160rpm was with 102mm cranks, tho - thing is, I don't
find I can actually pedal that much faster with shorter ones, at least
sustainably. Maybe it'll come with practice - not had the shorter ones
very long - but all I can say is: how on earth do you guys pedal so
fast? (e.g. 163rpm on _125mm_ cranks?!)
Silly thing is that on a bike (i.e., 170mm cranks!), I have a well fast
cadence (100-110 most of the time, up to 130 if trying to go
fast....once peaked out at 165rpm) - this doesn't seem to transfer to
unicycling, tho...:-(
