Good value.
Size: 2 Pack
Nice to have brand name product and quality at the same price as generics. This product does not immediately show up in searches for some reason. Use is simple enough although the long locking lever can be tricky in tight spots. I found very quickly this will NOT work with some kids bikes as it is too long and the lever locking requiring too much space. Will need to get something shorter and with a different style of locking for at least one end. Overall though, it is heavy duty, works well for adult and youth bikes. ... show more

Game Changer for Bike Rides!
Size: 2 Pack
The Yakima TubeTop Adapter is a must-have for anyone with a bike! I recently got it for my step-through bike, and it has made transporting it so much easier. The installation was a breeze, and it fits perfectly on my car rack. No more worrying about my bike wobbling during the drive! It’s super sturdy, and I love that I can use it with different bike styles. If you're looking for a reliable adapter, this one is definitely worth it! Highly recommend! ... show more

Sturdy and Secure
Size: 1 Pack
A must have for any bikes with a slanted top tube (ie. mountain bikes or women's casual bikes). The adapted bar holds my Trek Fuel level and behind the trunk out of the wind (see photo). Before (without the adapter), one of my wheels was up in the air and I was afraid that the wind would rip the bike off at highway speeds. With the adapter bar, it's a non-issue and I don't worry about it now. The bar feels very solid and sturdy and the weight limit should be adequate for most bikes (maybe not for ebikes or downhill bikes). The closure mechanism feels very secure and I like how the ends overlap for additional support. One nice feature is the rubber end has a groove that keeps the handlebars from twisting and prevents the front tire from rubbing on my bumper. I have another adapter bar (thinner bar with the white label in the photo) that feels much more flimsy (and has a lower weight limit). I thought the clamp would be useful on the cheaper bar to prevent it from extending, but it doesn't really work very well and isn't necessary. The two bars aren't even comparable, and I definitely prefer the Yakima top tube adapter. ... show more

Solid Adapter, Not Sure If I Need It
Size: 1 Pack
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. ... show more

Solid Construction
Size: 1 Pack
My wife’s cruiser bike can’t be easily mounted on our bike rack, due to the slanting frame. This product makes mounting a snap, and it’s very easy to use. The telescoping cylindrical bar should fit any size bike. I reviewed other less expensive products and was concerned that their light-weight construction could result in structural failure during transport. I have no such concern with this item; it’s sturdy and the connection to the bike’s seat post and bar stem is securely solid. I think it’s well-worth the extra cost for the peace of mind that the bike will still be on the rack when we reach our destination. ... show more
