Video Transcript for Will the Yakima HighSpeed Roof Bike Rack Fit Your 2019 Jeep Cherokee?

Colin: Hey everyone. It's Colin here at etrailer. Today we have in here at 2019 Jeep Cherokee. We're test fitting the Yakima HighSpeed roof bike rack. This is going to be a fork mounted or through axle mount roof bike rack. It's going to allow you to get your bike loaded up on top of your roof so you can conserve space on your hitch.

You're not going to have to invest in a hitch mounted bike rack, or even try to cram it inside your vehicle. This is going to come set up so you can add on some locks. So it has a plastic pop lock right here. Basically, the reason that it does not come with locks is because they want you to be able to key it alike with your Yakima roof rack system, if you have locks for that. That way, you don't have to deal with two separate keys.We're also going to have a spot on the back where the cable lock comes from.

But again, it's just going to have this plastic lock right here. We're just replacing it with that same key system from Yakima. And then it's less keys to deal with. You would just wrap that around the frame of your bike, right about right here, and then lock it up.Now the bike itself is going to be secured at two different points. Right now we're using the fork mounted option.

Once I get the bike removed, I'll show you what you need to do to use the through actual option. We just have a clamp on our fork mounts right there, and then we're going to have a strap on our rear wheel, securing it onto the bike rack. With those two points, it's a very solid contact. It's going to be very solid for the trip.Now I'm going to go ahead and remove the bike. With these roof bike racks, you always want to start with the strap, because even though the strap is doing a good job of holding that back wheel, the bulk of the bike is being held in place by that front clamp.

Because I have a bit of a height restriction, I'm going to go ahead and climb up this door jam right here. Hold onto the bike. Just pull this clamp out. That way it's loose. You can get the forks up and out, and then unload our bike. Again, you do want to be careful stepping down.Now right here, I can show you how to use the through axle option. We have our skewer right here in this clamp. All we need to do is loosen it up. Then we can pull the skewer out. Now we can use the through axle option on this bike rack. When you want to use the clamp option, the fork mount, you just turn this knob until you hear those clicks. Now, we're going to have three different rubber coated steel strap securing our bike rack to our roof rack. You can see they come up and under our roof rack and come up top. I'm going to go ahead and climb up here so we can show you guys that.All three straps are going to operate the same. We have, again, some more plastic locks that we can replace with those lock cores to provide security for our roof rack. Our back cradle can slide back and forth to accommodate bikes of different wheel basis. With this clamp, it just comes under our crossbar just like that. That rubber coating on the steel strap is going to make sure it doesn't harm or scratch the finish of our crossbars. It goes into this slot right here. Then you just push the clamp on like that to tighten it up. If you need to loosen or tighten it up, you just spin this little gray knob right here, left or right, depending on what you need, and then lock it into place like so. It's going to be the same system for our front two straps as well.Well, thank you all for watching. That's going to do it for our test fit of the Yakima HighSpeed roof bike rack on our 2019 Jeep Cherokee.Here on our test course, we'll start by going through the slalom. This is going to show us the side to side action. This simulates turning corners or evasively maneuvering. Once we get to the full speed bumps, we'll see the up and down action. This will be just like driving in and out of a parking lot, parking garage, or driveway. Once we get to the alternating speed bumps, we'll see the twisting action. This will simulate hitting a curb or pothole or driving over uneven pavement.

While I'm very impressed with the design and functionality of the yakima bike rack and would highly recommend them, I'm more impressed with the speed of free delivery and customer service of etrailer. Great product selection and great service!

The rack fits my 20 year old roof rack perfect.

Awesome customer service and great guidance getting me exactly what I wanted and making it easy

I just received the bike rack but since it's winter, I haven't had a chance to use it beyond a quick test mount to my car.
Pros: Easy to install and remove. Seems to be sturdy and when I had my bike mounted (see cons) it seemed to hold well.
Cons: This is a big one if you have 12mm thru axles. The included adaptor requires you to still use the 9mm skewer. My right fork axle threads are capped so I'm unable to use the included 12mm adaptor. I had to buy another 12mm adaptor (yay, another $60) to mount my bike.

You mentioned that you had to buy another fork adapter and I wanted to ask why kind of adapter that it was? Can you explain in more detail why the included adapter would not work for you?

by:
So far this has been a very nice bike rack. The integrated lock, the ability to accept a front fork with or without axle, have been nice. The action of the big tightening knob is good. And I had to take it off quickly to put kayaks on, and it took less than 30 seconds to remove from the roof.
by:
Yakima has fallen! Yet another outdoor company who used to actually serve the needs of real outdoors people. Now their products have become mid tier all purpose overpriced Normie slop. You would think an outdoor sports rack company selling a $300+ dollar bike rack might actually fit a real mountain bike. It does not. This appears to be for road bike forks or the very basic Walmart tier mountain bike fitment. And does this outdoor enthusiast company offer a wide fork extension part. Of course not! Do not buy if you ride a real mountain bike.

I am sorry to hear about your experience with this rack not working with your mountain bikes. We will reach out shortly and help find you a better fit solution and get this one returned.

by:
I already have one of these and needed another. The best and easiest rack I have ever used. A little pricy but what can you do?
by:
Not only did etrailer have what I needed- (many retailers didn't have this product due to covid related production issues), but it was delivered with tracking info and updates to my door promptly, with free shipping. The instructions were as top-notch as the service. I had my Yakima HighSpeed bike mount on the car and ready to roll within minutes. The mounting is solid, and the finish looks great. I am now able to carry any of my bikes securely on this mount... I will definitely order from these folks again!
by:
Purchased this rack to haul my mountain bike across the country on top of my truck. It was easy to set up, the bike was very stable on the trip, and the integrated bike lock cable was a great feature.
by:
This was the easiest part to put on the entire truck rack. Went on really easy, and the straps hold it down very securely. The 2 bikes don’t move at all on the rack! Plus the included locking cable is a great security feature
by:
Product works as described. Thanks for the great service and fast shipping!
by:
Can’t believe it’s already been a year since I have had these. Never had an issue with these to this day. Easy install and removal, great for through axle, look great and are built with quality in mind. I’m extremely happy with this product and would definitely recommend it.

  • Is There Roof Bike Rack that Fits Rhino Rack Vortex Bars that Fits Thru Axle Bikes
    Hey Ron, the Yakima HighSpeed roof bike rack part # Y78DJ is compatible with your Rhino Rack Vortex roof crossbars and also fits the 12 mm, 15 mm, and 20 mm thru axles so it would work great for you unless you have a different thru axle size.

  • Differences Between Second and Third Generation Yakima HighSpeed Roof Mount Bike Racks
    Great question, Kris! The Yakima HighSpeed Roof Bike Rack # Y78DJ is the newest edition of the HighSpeed and is replacing the part # Y02115. There aren't any life-changing upgrades to the newest edition, but enough that I recommend going with it over the older version. For example, the newest model has an off-road rating (which doesn't matter to a lot of people) and then it fits with a slightly larger wheelbase - up to 50" as opposed to 48" that the older one was rated for. Another subtle...

  • What is Your Recommended Roof Rack and Bike Rack for 2024 IS350?
    Hello Alec, No, the # C11372 fit the Lexus IS 350 through 2012. The last year that they made a hitch for the IS 350 was 2021. There might have not been a high demand for them, or the IS 350 is no longer rated for a hitch. I do have a different option for you. Your best bet is going to be to get a roof rack like the Yakima BaseLine Roof Rack # Y88XB. The # Y88XB is a kitted part number, so it will come with everything you need to get the roof rack on your vehicle. Then you will want a...

  • Does Inno Truck Bed Cargo Rack Come with C Clamps and Crossbars
    Hey Travis, yes the Inno Truck Bed Cargo Rack # INRT101-65 does come with the C-clamps and the crossbars needed to complete a rack in the bed of your truck. Then for a bike rack the Yakima HighSpeed roof bike rack part # Y78DJ would work as well. This works with thru axles and is compatible with the Inno bars as well.
