Can Topline 2 Bike Carrier # UG2500 Carry Square Tube Frame Bikes


I have three questions. First, do the clamps only fit round tubes? The top bar on my mountain bike is rectangular and 1 1/2x 1 1/2. I realize that if it doesn’t fit the top tube, I can attach it to the seat tube. Second, if the clamps do not fit the top tubes and we want to carry two bikes, what is the length of the clamp? One bike would have to have two clamps on one seat. I can temporarily move the seat up to transport but don’t know if there is enough tube to keep it stable with two clamps. Last, one of the reviewers stated that this would not work if the bikes were not the same size. It seems like if your going from seat tube to seat tube, there should be a point where they are on the same level. Just concerned about my second question about how much space I would need on the seat tube. Thanks!


Expert Reply:

The clamps of the Topline 2 Bike Carrier # UG2500 are shaped in such a way that they are ideal for a round or oval tube, but they can be also used on a square tube as well. Or if you felt more comfortable you could attach them to the seat post like you mentioned.

I attached a picture that shows that you can carry multiple bike heights with this rack as well.
