Today we're going to be taking a look at the replacement speed knob and wedge assembly for the Yakima bike racks, part number 8880508. The Yakima replacement speed knob is to be used with the Full Swing, Swing Daddy, Ridgeback and Full Tilt bike racks when their speed knobs are either damaged or the threads at the end are stripped out. It comes with the black knockout here which you're going to remove that and it has the control key to remove the lock core from your previous speed knob to replace it into this one. To get started we'll first remove our wedge piece here by unscrewing it and set it aside now we'll grab our damaged speed knob and start replacing it as well. Now we'll move on to our bike rack and have our Yakima Ridgeback here on our table and the issue with is the thread is stripped out in our wedge. We'll push that off to the side, remove our speed knob as well, now we'll get our new one and start installing it. First since this is a Ridgeback, we'll have to remove this top piece from the wedge. Take our allen tool, unscrew those two allen screws, move onto the one on the inside.
Now we can grab our new wedge and install this piece on top of it. What this piece actually does is it takes up the additional space on our Ridgeback so it'll fit properly in a two inch hitch. If you we're to convert this into an inch and a quarter you would remove this piece again. Finally, our second screw, one last turn to make sure it's nice and tight. Next we'll move onto our lock core switch out here. To remove this plastic cap, we'll take a small flat bladed screwdriver and just pop that out, very easy, and then we'll take our master key here put it into the core and it pulls out like so. Again, very easy.
To place it into our new lock, we'll push it in holding onto the end of the core and pull it out. Now we're ready to install this. We'll take our lock washer and install it on our replacement speed knob here and we'll install it at the end of the shank like so. Then we'll take our wedge and we'll just start to screw it in on the inside. You see the cutout here, you want to make sure that the wedge fits along that area. Here's the end of our speed knob so we'll just match them up, just start threading it in so it catches.
Now we can place it into our vehicle, slide it into our trailer hitch and go by the normal installation procedures for this bike rack. Now we'll go into the end here and tighten down our new knob. As we tighten it down, you'll notice that the shake and play has gone away which means it's working properly. All right, it looks like we're ready to go, we'll lock it into place so it's secure in the vehicle and now we can load up some bikes. There you have it for the replacement speed knob and wedge assembly part number 8880508.

We love how etraler easy it was to order the part from etrailer and get it quickly.
We have traveled all over the country and love its versatility of the bike rack. But the Yakima SpeedKnob placement could use some redesign. It is designed to be too low - below the Trailer hitch. No matter what vehicle the bike rack is on SpeedKnob wedge will bottom out when backing out of steep driveways or curbs thus damaging the wedge. This is our 2nd replacement in 18 months.
I bought a used Full Swing Rack that was missing a few parts. The Yakima Website was out of them all (and according to other reviews on their site, had been so for several months), and Yakima didn't have a date on when they expected to get them in. etrailer had the parts available (with one exception).
I thought this was going to be a knockoff SpeedKnob, but it is a genuine Yakima product. As such, it fits perfectly. It it super easy to add a lock tumbler and install on the hitch rack.
Awesome product just as needed and great fast shipping
I really enjoy the customer service at etrailer.
There was a slight mixup on my order but etrailer sent the part out right away, no questions ask.
Arrived early, perfect fit
This is the third time that I have had occasion to use etrailer since I purchased a bike rack for my car a number of years ago. Each time the service is great--the website is easy to use, the goods are reasonably priced and they get to me in just a few days. In this case, I needed a new Speedknob and wedge assembly used to tighten my Yakima Ridgeback bike rack into my hitch (the old one stripped out). I got it quickly and once again, I'm ready for another spring of bike riding.

Great—I just put the bike rack on the car getting ready for the spring and all is fine.
Great communication!! Fast Shipping!! T hanks!!!
Great. It took me ordering this new item for the missing item to show up. I will likely hold on to this piece longer than I have the bike rack forgetting what I purchased it for but that it cost me to have it replaced.
Ordered the replacement knob and wedge. Short install video was extremely helpful. Took all of 3 minutes to install. Saved having to purchase a new Yakima rack. Fit perfectly.
Oh, so my issue wasn’t that the old metal piece that goes into the hitch was stripped, rather that the red wedge mechanism wouldn’t engage the shaft, eg it spinned endlessly without loosening or tightening. So to remove I had to twist the shaft with a pair of pliers to unthread the existing shaft. (Included this comment in case it helps someone)

I really appreciate all the information you gave - thats what makes a review helpful for other folks! Thanks for taking the time to do so :)
Perfect match for the original that I had to replace. Getting lock with just one key is a minus. Bike racks go on cars, cars come with two fobs. Good to have a spare.
Simple, straightforward replacement!
A good replacement part for our bike ra ck.
Easy online ordering and at my house on time and fast.
Misled. Sure, the ad shows (sold separately) for the lock core down in the description.
However, the image of the key with the lock in the product combined with the owners manual showing that the lock core and keys are indeed part of the package drives this to a 1 star. History shows I’m not the only one. Just include the lock core and keys in the package, as the instructions you sent me show.
Excellent product and delivered quickly!
Bike strap replacements are great, all work well.
It was delivered as ordered and exactly what I ordered.
Perfect replacement for my original par t.
Exact fit for my Ridgeback 4
Thank you
Exactly as pictured, and quick shipping.
Product was great and I had excellent customer service when ordering.
Fits like a glove,im glad I didn't have to buy a new rack, thank you for supplying the replacement part.
Great customer service, got exactly what I needed quickly. Thank you!
It didnt come with the lock which makes the product unusable. I have tried to call to get a refund or lock sent to me

It seems odd to me as well. The SKS lock cores are available separately as # Y07202
I’m so happy to be able to use my bike rack again. Quick fulfillment of the order and accurate description of the product helped make it a successful purchase.
