They’re both great cranksets… Perhaps the KH / Onza is slightly stronger, but you’re going to have trouble breaking either! Strength isn’t an issue.
The K1 cranks have very little Q factor (distance from the pedal to the frame) which makes them give you a very smooth ride. It also helps (I feel) with getting speed on rolling hops. They’re more suited for street riding.
The KH / Onza Cranks have Q-a-plenty so you’ll get the extra help with riding skinnies and on pedal grabs.
[B]They’re more suited for technical trials.
[/B][COLOR=Black]Neither are better, it’s just down to preference and what style of riding you’re after.
My advice is that if you’re strapped for cash (and you want 125mm) then go for the Koxx-One Cranks. They’re nice, smooth and are £25 cheeper than the KH/Onza cranks.
AND, almost no-one in the US has them!!!
the only thing I find with the KI is that they are very steep on the top for doing seat drops and wraps, while the KH ones are nice and have a rounded flat top to them. also because the KH are angled out, theres less chance for your feet to hit the spokes.
Wait up! I do know somebody that broke their K1 cranks. He is ntappin on these forums, so you should be able to find him. I believe that because it is the international spline system (or whatever ISIS stands for), you can get new cranks from almost anywhere, though.
Thats brilliant Eroick, can you name one other manufacturer of isis splined unicycle cranks other than Koxx???
Bicycle cranks are rarely come in the shorter lengths necessary for unicycles and often have cogs on the right-hand crank.
If all splined unicycle manufacturers were to adopt the Isis splined system that will be great, as we will be able to select whichever cranks we like. Till then the Koxx Isis cranks are yet another splined system incompatible with all the other unicycle splined systems
if you’re doing muni you can nearly always find 170s in ISIS from a variety of manufacturers. shorter than that and you might be in trouble. i know redline makes a 165mm cranks set ISIS for children’s mtn bikes. don’t know how hard it is to find though.
