Will it hold on both the seat post and the frame? Post is round, frame is not

If you have a very light carbon/ aluminum bike then yes maybe. But it's probably best to use a rag or towel and have it clamp on the top tube. If you really need to clamp it to the seat post is recommend a sturdy park tools stand.

The clamp opens up pretty big, I have a ciomfort bike with a large top tube it easily accomodates, so probably yes, if not the clamp rotates and you can hold it by the seat tube, good luck

I believe it will work. The vertical posts have a height adjustment to accommodate different bike frames.

I checked the diameter of both the units I bought and it looks as if 1" is the max diameter of the post clamp.This would not fit my seat post but the rear frame wheel support.Hope this helps... Please note that the most recent one purchased only had the large size clamp and came with two dead batteries. Perhaps this was a customer return.

Mine went on an old Trek mountain bike. There seems to be a lot of adjustment room to it and I think it should fit any seat post. I used mine to support a home made trailer and it took a lot of abuse without turning on the post.

Maybe if bolted to a post, but difficult to get to both sides and does not hold tight enough.

If your bike doesn't have threaded holes at the top of the seat stays near the seat post you'll need to buy a bracket to mount it. This one worked for me: BIKE RACK PART SUNLT MONOSTAY ADPTR RR1p

I no longer have a bike but when I had it I did not attach it to the seat post. I tied it to the back of the seat (which had brackets) so it never shifted and worked very well. (Probably not the answer you were looking for - sorry.)

When you attach it around the bed frame correctly then yes it should hold the weight

Yes, but only if you mount it on the top of the frame so it's hanging down. It depends on how large the bike is as well.

It fits on the seat post between the seat and the frame itself which is about 1 & 1/4 inch, however the mounting is so unstable that it required me to support the handlebars with a tie down attached to the ceiling in order to stablize the bike for tuning.

Yes, as long as there is enough space for the clamp to be attached to the seat post. The clamp needs a bit more than 2 inches of space.

If the seat that's on it has rails, it should fit. You will have to loosen the top of the post enough for the rails to slide out. Put this seat in its place and re-tighten. You shouldn't need a new post.

I have it mounted to the frame rack. It is a great unit. They have a lot of adapters to mount it to the bike. Don't think it would mount to seat post.

You'll need to either put it around something thicker or make a spacer (I made one for my saddle out of a block of wood). It should stay there fine but it'll wiggle around unless you wedge it

as long as you have a seat post that fits into the bike frame at one end of the post, and at the other end of the post, fits into the bracket that should of come with the seat. Any problems and the bike shop can do a cheap fix...
