Question: Does the stand support a bike if clamped to the seat post or must it be clamped to the frame?
Document: What else can I say about this, I didn't want to dump a bunch of money into a bike stand so I purchased this and wasn't disappointed. I actually have my mountain bike clamped to the seat post and it works fine. Like I said, it's a good, inexpensive stand!
I can raise, lower or re-clamp the bike either on the seat-post, top-tube or seat-tube. I usually try for the best center-of-gravity spot but sometimes the weight maybe to the front which the stand can tolerate, but I wouldn't overdue that on any portable stand.I have placed my wife's cruiser on this stand just to see how it would handle the 39# and it was okay; just need something under the front tire to hold it at level.
I had to assemble onto the bike the handlebars, front brake caliper, pedals and front wheel; I adjusted the stem/headset, derailleurs, all cables and shifted gears while spinning the pedals. So, tuning a bike is relatively simple on the stand. I could clamp the bike at the seat tube, seat post or top tube; the top tube gave a better center of gravity; the bike could be tilted or the height could be dropped.
I bought this stand to be able to work on my Trek bicycle. I am happy for the most part with some exceptions.The stand is good heavy material which is easy to assemble. If folds up nicely and can be stored in a corner somewhere. My main problem is the clamp that holds the bike frame. It is hard to adjust without two hands and it is difficult to get it tight enough to old the frame at an odd angle.
I was pretty excited to start being a real biker and work on my bike. However I didn't really read the directions too closely, figured how hard can a friggin' bike stand be and then promptly broke it. The clamp that holds the bike was a little confusing and kept popping open, so I just kept tightening it until lo-and-behold the plastic frame snapped.Can't really blame any one but myself, but I guess I didn't expect it to be that flimsy either.
Put it together quickly. Gauge of metal is heavier than I expected, which makes it sturdy. Nice to not have to bend over and work on my Cannondale Quick CX-3. Nice not to have to lay bike on its side after removing a wheel. Bike clamped in nicely and stand does not tip over.I would recommend this to a friend.
In addition the rubber pieces fit loosely on the end of the metal gripper and come off easily. The entire gripper needs to be lined with non-slip, thick rubber. As it is, the entire frame can swivel and slip since the gripper really does not have a good hold of the frame.The stand has a wide base for stability and I like that because it refuses to tip at all.I think this is a good product but needs some engineering upgrades on the frame gripper.
this stand is very similar to the RAD and the Conquer Portable Home Bike Repair Stand, which was no longer available at amazon.
This is a great value. Its a strong stand, easy to set up/take down and holds both my road bike and mountain bike with no problem.
Very sturdy bike stand. I refuse to pay a bike shop to do maintenance on my bike if I am able to do the repairs myself. You will be very pleased with this bike stand. Professional quality.
