There are four basic deficiencies with this product:

1)It is not spring loaded so it is not as secure as it could be.
2)Extending and contracting is difficult and not smooth, making it hard to adjust to any length other than fully extended or fully contracted.
3)The "loops" open up or down and not sideways which makes it more cumbersome to install on the bike.
4)The buttons that you must press to open the loops are recessed too far down making it difficult to open

The Swagman (Swagman Bar Adapter Deluxe)and the Sparehand SpareHand Bike Frame Adaptorbike frame adaptors do not have these flaws and are much better.

I bought this for my daughter's bike so it would fit our new Yakima Ridgeback 4 which was given to me as a gift to celebrate my new fantastic Nissan Rogue SUV. I am in love with the rack, but that's for a different review.... Anyway, so today, we were loading bikes onto the rack for the first time ever.

To be fair, I think this adapter is a whole lot better than the old ones we had years ago when the kids were little. The rubberized ends and the good fit around the handlebar post and the seat stem surprised and impressed me very much.

The huge problem for me is that the opening mechanism is too difficult... Impossible, in fact. You have to press little buttons down into little holes until the movable part of each end can be opened. It takes strength, and it takes steel thumbs. I seriously CANNOT do it. **It hurts my hands**. It wasn't very easy for my 22yo daughter to do it either. But she somehow managed. I need something that will work for me.

Anyway, so while we were loading the bikes onto the rack, it became quite evident that my bike also needs an adapter. So I went back online to Amazon with plans to order another one from Yakima. I really thought there were no major differences in adaptor features, i.e. that the opening mechanism is the same across the board. But you know what? It isn't!! Other companies have come up with better designs!

So for my bike, I have ordered a Swagman Bar Adapter Deluxe. And I'm seriously thinking about returning the Yakima one. Yakima has changed so many things about their bike racks recently, made them incredibly outstanding, with great ease-of-use features. But the adapters are stuck in time. Basically the same as ever, even though everyone complains about how difficult they are to open. Hopefully they will get the message and make this seemingly simple device even better than their competitors. Meanwhile, I am going with the competition this time.

I got this frame adapter because it has the shortest length around:14.5 inches. That is short enough that I can use it (barely) on my daughters 16" frame. I don't think all 16" frames would fit, but I think you should be safe with 20" frames. All the other adapters out there seemed to have a longer short setting - several inches more.

And for its stated purpose, it seems to do well. It works just like any other frame adapter I've seen and is nice and solid (and a bit heavy).

This bar arrived today and I am discouraged that it was too long to fit on my wife's Trek Navigator 2 bike.

Size and length listings on the sales site for this item would have been helpful.

I bought this to work with a bike without a top tube that I currently have to mount "upside-down" and use the angled downtube to mount. However this put the bike up very high and blocks rear view. However, this adapater does not work well with very large (ie: long) frames. The problem is in the basic design that this adapter will almost "pull apart" and not stay very solid at full extension. It almost feels like it will snap apart when fully extended and loaded with the bike on the hitch. I can't use it with my bike, but it does work with my kids bikes which are much smaller. For my bike I have tried a friends Saris adapter that works much better for a large bike and I am looking into buying this instead.

Period. What can I say. Don't know why some gave one star reviews. Prevents accidental scratches when mounting it on the rack. Helps stabilize handle bars when mounted. Fits my front and rear lights!!! Love this bar!!!

Purchased two for use with my wife's and daughter's mountain bikes. We have the Yakima Double Down-4 bike rack and the Tube Top adapts the 26" women style frames to fit securely and easily. Push button release on sides can be a bit tedious for big fingers but rigging on and off the bikes can be handled by even my 9 year old daughter. Give your self an extra 15 minutes the first time you use them and make sure your seat post latch is tight as possible since this mounts to it.

First off, this is a very solid adapter, and should do the job very well for those who need one. I have compared it to others by Saris (my favorite), Swagman, and Allen.

The Yakima Tube Top does not have an internal tension band, but it really doesn't need it. Once it's sitting in the rack cradles, and strapped down, it's not going anywhere.

The one thing that I really didn't like is that it has an exposed nut on one side. It's not anything you would really notice...until your rack strap catches on it, which mine did often. I also think that this exposed nut and screw end might be prone to rusting over time, although I really can't be sure of that.

For me, the biggest issue was whether I actually need a top tube adapter. My hybrid bike does sit on the rack at a fairly steep angle, but it's very secure when strapped down on the rack, and even at the steep angle, the lowest (front) tire still has 19" of clearance from the road.

When I called Yakima about the angle of my bike on my Yakima rack I was told I needed this Tube Top. The problem is that while it improves the angle of the bike on the rack (and it's only a marginal improvement), the bike sits lower, and the lowest tire road clearance is down to 13".

I don't plan on doing any real off-road driving, so I really don't know what the minimum safe road clearance would be. It just seems to me that 19" of clearance is better than 13". I really don't know how important it is to have a bike hanging on a rack at about a 30 degree angle instead of a 40 degree angle.

Of course Yakima wants me to keep the Tube Top, but I'm not sure if I really need it.
