Sure Bill, G, here is the link. http://www.murraytourdeforce.co.za/ Once
you get to the website, click on "Cranks".
I call it a blade crank, because, well it looks like a blade, to me. Doubt
it will help me go faster; BUT at least it will be COOL Looking!!!!!!!!!

How much stock do most people put in matching leg length to crank length?
I'm 6' 2" and have 165 cranks on all 3 of my trikes. I find them pretty
comfortable and usually spin in the 70 to 90 rpm range (or try to). If I
understand it correctly, shorter cranks help spin faster, more comfortably,
at the expense of power, while longer cranks help with leverage to put power
to the pedals but at the loss of comfortable high pedal rpms. ? Yes/no? I
can comfortably run at 28 to 30 kph on flat ground with bursts to about
40kph. I don't feel "jammed" in my pedal stroke and my knee pain (doing
everything else BUT cycling) is non-existent. A friend of mine who is
likely around the 5' 6" mark uses 175s and swears by them. According to the
chart, I should be using 180s and while he claims that there is an "optimum"
range of motion he doesn't seem to go into great detail on it that I could
see.

Has anyone here received a noticeable difference in comfort and/or
performance by switching crank lengths?
