Has anyone ever tried this crank length change? I think that my 145’s are too long but i dont want 125, they are too short. I want a mix of speed and stability for a short trials rider. I am just affraid to buy these, and then i wont feel enough of a change.
137s are realy nice. I have them on my KH20 they are long enough that you get good controll when doing trials but short enough that I can get enough speed to jump sets and they also flip realy easy.
thanks alot… one more thing…
my uni is a qu-ax trials, with yellow hub, but itrs not the new one, and i heard that it was not compatable with KH moments b/c its not ISIS. is this true? and if it is, what other company make a quality 137mm that will fit my hub? or should i get a whole new hub and wheel(i dont want to spend that much).
If it’s not the new yellow ISIS hub then there is no 137mm crank out there for you. If you are really dead set on getting 137mm cranks then you will have to upgrade the hub to ISIS, if you get the Qu-ax ISIS hub you will be able to reuse the same rim however if you were to go with any other ISIS uni hub you would need to get a 36 hole rim. Personally, I don’t think the 12mm difference is worth all the time and money.
I am in the process of doing the same thing to my old qu ax. I bought a moment hub and 137mm cranks but the hub doesn’t seem to work to well on my frame because the flanges are so far apart, and they almost touch the sides of my frame. I am trying to find somewhere that sells qu ax ISIS hubs so that I can get that hub instead and still use the moment cranks.
You probably shouldn’t get the moment hub because you will run into the same problem as me and you will also need a new rim.
Going back and forth from Profiles and KH moments, I only feel the difference going up to the 145s, specially if the seat is somewhat low. But going from 145 to 137s feel really nice and fluid.
i would like to start doing a bit of street but i think ill just stay with my 145’s for now. if i upgrade mu hub/crankset later on i’ll go 137 then, since the general consensis is that its not worth the $$ just to change now.
I like the way you think my friend. Good luck with it all though.
1) Well i wouldn’t say it’s too long seeming as you would have better control of the unicycle and whatnot. But sometimes your mind thinks “what if i got shorter cranks”. But it’s whatever you make of it though if that makes sense. 2) I wouldn’t know considering i don’t have DEFECT.
