I agree it's a tad short, especially since my bikes tend to be big. I've found I can use it with just about any bike if I adjust the angle of the mount but I've also thought about adding an extended tube. If you try it, let me know how it goes and maybe I'll cut mine up too.

I often used the seat tube or top tube on my old stand but this one seems like it has a pretty stout clamp and I'm worried about crimping a tube with it. If the clamp was adjustable I'd be less concerned but it doesn't appear that it's possible to adjust the clamping force.

BTW, there was one for sale on my local CL last week for $80. I thought about mentioning it here but shipping probably would have been the same so I let it pass.
