Question: Will the clamp hold a bike by the seat post?  I have an odd shaped frame folding mountain bike.
Document: It does not hold the bike in an unbalanced position. The "clamp" that holds the bike by the frame or seat post cannot be operated with one hand cause both the butterfly nut and the hand turn, turn together making impossible to tighten.With that said it is cheap enough so i'm too lazy to take it apart box it up and return it.
its not really bad at all. but if you intend on trying to hold the bike by the seat post, think again.It does not have the clamp strength to hold it level. Holding it by the cross tube works but is not always ideal, especially if you are working on the cables. but it does work and i'm not gonna really complain
It works and for the price it's a huge improvement over not having one.The main issue I have with this stand is that you can't operate the frame clamp with one hand. You need to hold a bolt with one hand while screwing (closing) the clamp. This means you can only attach the bike from the horizontal tube of the frame and if you don't have an horizontal tube you can't do it.
for simple things like changing a tire, probably good to use but i needed it to torque the crank my pedel is attached to and if i'd have pushed any harder, the clamp would have torn right off. Also not the best for mountain bikes or cruisers cause the clamp doesn't open up wide enough. you gotta work it a bit but a speed or race bike with a small frame would be ok
I haven't found any problems with securing the bike, either by the top tube, slanted top tube, or seat tube. I simply hold the bike in the air, the best I can, and determine the most balanced way to clamp it in the stand. I haven't had a single problem with any bike not securely held.I'd recommend this to anyone who does the occasional bike maintenance/repair and doesn't mind the awkward nut/bold clamp assembly. It's a great tool to have in the garage!
Although I have to use the stand in a different way with my mountain bike, it is really designed for a standard diamond frame. Cost was a factor, and I cannot afford a more expensive stand. Very well made if used for regular bikes.
I'm very happy with this. I have used it quite a bit and have not had the troubles that some others have. I found the price unbeatable. I have a Giant 19&#34; mountain bike with a very large tube on the lower frame which the jaws of the stand will not fit around.
Ok so no, it's not a park stand but this thing isn't ever going to work. It won't even hold a regular mountain bike without slipping, and like others have tried to tighten only to have the cheap Chinese garbage fail.
The return process is easy, but aggravating to have to do so.I don't know if I have done the right thing, but I ordered a replacement stand. As I don't do major bicycle work I hope the stand will hold up to do the occasional work. Once I get the replacement I will post how it goes with the next one.
I'm not sure what the problem some people are having with the clamp holding their bike at various angles. I have had all 4 of our bikes, a touring bike, a mountain bike and 2 hybrids on it and the stand had no problem holding them at any angle I wanted. Perhaps they have changed and improved the clamping system, but I have had no issues with it whatsoever.For the price I paid, I can't say anything bad about it.
