Replacement Knob for SportRack Hooks - 050045

Average Customer Rating:  4.8 out of 5 stars   (55 Customer Reviews)


My cheap, thin, round knobs for my bicyle rack cracked under pressure of loosening and tightening the bike clamps. Your replacement knobs look like they will withstand hand cranking indefinitely. They were inexpensive. I appreciate being able to locate replacement knobs without trashing the whole rack assembly. Thank you for having old fashioned selection and service. I'm happy with what I received.


I ordered a replacement part for my SportRack bike rack. I was a perfect fit.


I was having a hard time finding a replacement piece for my bike rack. I came across the website and it was very easy to navigate, ensure i was getting the right part and for a fair price. Shipping was easy and nice that it had updates on when it was coming.


Great replacement knob for my sportrack bike carrier. Works like a charm


Was as depicted. Works fine however, these knobs do wear out. Just had to replace the knob 1 year later.


This knob fit my 12 year old Xport hitch mount bike rack. Didn’t think I could find replacement parts anymore. Thanks etrailer!


Was the incorrect knob provided to me it did not fit my roof rack

This knob is used to tighten the bar on a bike rack. I think the one you are searching for is here: Item # SR05005600000.

I just put the replacement knobs on my bike rack. They fit
beautifully and are an exact match to the other knobs. I am pleased as this is the 1st time I've ordered a replacement part online!

My husband did notice that the knobs did not seem to have a "locking ring" to keep the knobs from loosening; so I have to be sure the knobs are secure.

Great. No problem.

Ordered some replacement hardware for my older model hitch mount Sportrack. Although there was a delay in the shipping, I was well informed the entire time and when the parts came, they were a perfect match.

Exactly the part I needed. Still working great.

I just ordered 4 different knobs in hopes that one of them would be the correct thread size to fit my old 2 bike Xport bike rack I purchased from Performance Bike in 2005. Well 2 of them fit! They were made for SportRack bike racks so I guess that brand is similar. Very happy with the purchase.


I got the part quickly, fixed my bike rack and I'm ready to go! Thanks, etrailer!

Works great! The part was exactly what I needed.

I got the part I needed because etrailer had good selection and prices. I don’t know if I could have got the part anywhere else but the result is I can keep using my bike rack. Fast service too!


So glad that you guys stock parts for the Sportrack. Love the rack and just needed some new parts for it.


I just bought this to replace one broken on my XPORT flatbed rack. Works as an original part.

etrailer service was fast.. highly recommended.


Service from etrailer is always great. These bolts and knobs work well. They're a soft metal so it's easy to over tighten and strip which is why I had to order extras.


Nice and smooth transaction. Pieces works fine. Super follow up with customer.


Exactly the larger knob needed for an Xport platform bike carrier arm that had come off & been lost while driving. Shipped fast and in protective bubble envelope. All good.


Hello Julie,
My order was delivered
today. provided a first-rate customer experience from start to finish! Thank you for your direct contribution - it was a pleasure speaking with you last week.


Google vers good


The part I needed, a little pricey, but otherwise what I expected.


These replacement knobs work great for the Sport Rack Hooks on my bike rack. I'm glad I was able to find these as replacements.


I ordered this knob for our SportRack. The original knob ended up getting stripped and would not tighten properly. This knob is an exact replacement. It arrived quickly and works great!


The product was a replacement part for lost bike rack part and it works as required.


I received exactly what I ordered. Perfect fit for my bike rack. The order was delivered sooner than I was expecting. I would order from this company again and will refer my family and friends to this web site.


Great product and fast delivery! Would highly recommend.
