Video Transcript for Review of Thule Replacement T2 Bike Carrier Locking Ratchet Arm Assembly - 752-1272-001

Hi there, I'm Michael with Today, we're gonna take a quick look at this Thule Replacement Locking Ratchet Arm Assembly. This is going to replace the locking ratchet arm assembly for your Thule T2 Bike Carriers. You can see the two different part numbers there on the screen, so if you have either one of those, this is gonna do a great job of replacing that original locking ratcheting arm for you. Because it is a direct replacement from Thule, you can trust it is going to fit right in place, give you that full functionality again, you're not gonna have to worry about compatibility issues or anything like that. And so, it is going to have this ratcheting arm that will allow you to tighten everything down, make sure your bike is nice and secured, we also have the locking cable here, so that we can get our bikes securely attached and not have to worry about someone coming along taking off with our bikes.

The lock core is sold separately, so it's not gonna come with a lock core, you might be able to reuse the original, make things easier for yourself. As you can see, we're only gonna have 1/2 of this cradle, so you'll need to reuse the hardware and everything from the original, but if you are just needing to replace that original ratchet arm assembly, this is gonna be exactly what you need. That completes our look for today. Again, I'm Michael with, thanks for watching..

Replacement Locking Ratchet Arm Assembly for T2 Bike Carriers - 752-1272-001

Average Customer Rating:  4.8 out of 5 stars   (76 Customer Reviews)


I recently purchased a 29" bike and unfortunately my older T2 bike carrier only accommodated up to 26" bikes. I purchased a replacement locking ratchet arm assembly for my T2 bike carrier from etrailer and the installation was a breeze (approx 30 minutes).

Last year I ordered a hitch for my truck from etrailer ( so did my Father) and I was just as pleased as I am now with the ordering process, product and installation process. Thank you etrailer!


Works exactly as reported. Pretty easy to install, too. This ratcheting arm is about 1.5 inches longer than the previous version so it raises the support arm to allow clearance for fat 26 inch tires, or mid-fat 29ers. The old arm/ratchet system BARELY fit around a 45NRTH Dillinger 4.0 fat tire on a 26er, with pretty low pressure.

I didn't account for the fact the new arm also has the integrated cable lock system, so I had to order 2 matching core locks to take advantage of that functionality. I already have the arm locks, but two locks are better than one.

The pic is of a Niner ROS plus with 29x3.0 tires. Fits with room to spare.


Was perfect upgrade to my Thule classic 917, really happy parts are interchangeable! Thank you


I bought this replacement arm to accommodate larger wheels like 29er. I use it primarily for my Fatbike with 4.8" tires.


Product looks great and delivery timely. I realized after examining the contents that all parts needed except....multiple replacement screws/bolts, washers and nuts were not included. Upon removal of those parts for I’m well worn bike rack none of them were functional and needed replaced. 6 pairs of the aforementioned parts would have been appreciated.

Thule lists all of their replacement parts individually. If you need the screws and nylon locknuts that attach the hook to the assembly, you would need the Replacement 10-32 x 1.5 Phillips Screw # 853-5972
Replacement 10-32 x 1.5 Phillips Screw for Thule Sidearm Roof Mounted Bike Carrier
and the Replacement 10-32 Nylon Locknut # 853-5973
Replacement 10-32 Nylon Insert Locknut for Thule Sidearm Roof Mounted Bike Carrier
. For the bolts, washers, and clamp for the base of the arm assembly you would want the Replacement M8 x 1.25 x 25 mm Bolt # 853-5976
Replacement M8 x 1.25 x 25 mm Bolt for Thule Sidearm and T2 Bike Carriers
, Replacement Washer # 951081654
Replacement Washer for Thule Spare Me Spare-Tire-Mounted Bike Rack or Sidearm Roof Mounted Bike Rack
, and Replacement Bearing Clamp for Thule Sidearm # 753-3591
Replacement Bearing Clamp for Thule Sidearm Roof Mounted Bike Carrier

The quality of the product is well-made, and eTrailer service and pricing are excellent, however I can not recommend the Thule T2 Classic, or any version of this style bike carrier. After owning the T2 2-bike carrier, plus 2 bike extension for many years, the stress finally got to me, and I sold it to someone else.
The problem with these style bike racks is the further from the hitch, the more each bump in the road is exaggerated, and the whole rack reacts like a diving board, to the point the furthest bike was “bounced” out of the tray several times on road trips. Also, a simple google search reveals the many ways these racks are easily defeated and don’t actually secure the bikes at all.
I spent the money and bought a Recon Rack, which holds 6 bikes vertically, by the front wheel. Much larger rack, but more secure.
Again, etrailer is great, and I will continue to shop with them, but I can’t recommend the Thule T2 Rack, or any parts for it.


Great replacement for a part after the lock was broken and cut. Saved the need to replace the entire rack


Still working perfectly after a year, nice to be able to fix the existing rack instead of buying a whole new one. Thanks for carrying the replacement parts etrailer!


works well


Exactly what I needed to carry my 29+ bike and my Fat Bike. Very easy to change out and I was able to sell my stock arms. I will likely purchase 2 more because I have the 2 bike add on. Cable lock is a nice feature. It wouldn't stop a pro but will slow an opportunistic thief.

Great! I use this rack almost daily. Things that need improvement are the latch for lowering the rack - could be a smoother operation. Also, it would be nice if there was a retrofit to tighten the hitch into the receiver. As far as holding the bikes securely, Ive had no issue.

Upgraded my older Thule T2 Classic with the new arms (752-1272-001) so that my 29x2.6 wheels would fit securely. The upgraded arms installed easily, and my larger wheels now fit as intended. I also installed the lock cores (TH450400) so that I could use the arm locking mechanism and the included arm cable lock (there are two separate lock cores per arm). Super easy install.


Seems to be a good product for an old rack. Installation was straight forward and took only a few minutes. Can't give 5 stars because for what you're getting, the cost is too high. It's cheaper than replacing your whole rack so you're kind of stuck buying this if you need new, longer arms.

I ordered a part for my bike rack. It was delivered when promised. I was emailed from etrailer throughout the ordering process up to the delivery to our front door. I've used etrailer on on several occasions and will continue to do so.


I bought a new Bronson and needed that little bit more of a reach than my old arm could handle. This worked just like I thought it would.


This replacement worked perfectly on my Thule T2 hitch rack. A light pole unfortunately snuck up and ran into my rack damaging the ratchet arm. Found the replacement part with ease on etrailer's web site. Shipping was super fast and the installation took literally minutes. Saved the expense buying a new rack.


I got arm assembly to squeeze some more life out of an old Sportworks rack. The rack was purchased by a family member in 2004. Amazingly, this part fits perfectly on the old rack. Thule knew a good design when they saw it and didn't change a thing for the ratchet arm assembly. The old mounting hardware mated perfectly with the new part. The old arm is still in great working order, however I needed extra length for the larger diameter 29er wheels I now ride. The price was great and worth the gamble to extend some life on a classic hitch rack. Note-you get exactly what is shown and mentioned in the part listing. If you need extra mounting hardware, a replacement hook or cylinder core locks, you'll have to order those separately.


Purchased some replacement parts for my 10 year old T2 Thule rack and brought it back to life! New swing arms for 29in tires with locks and new bushings have made all the difference. Easy installation and replacement and quick turn around from etrailer.


The arms were very easy to install on the rack, turning it from a non-cable-locked 26" rack to a 29" cable-locked rack. I will say that the plastic covers (with the "Thule" stamp in the picture) feel looser than the old ones when not engaged with a bike. Overall I am happy because now I can hold a 29er without having to get a new rack.


Perfect fit for my older Thule T2 Rack. I recently got a 9er Mt. Bike to add to the collection and realized my T2 rack was old enough that it was made before 29 inch bikes where popular... So the arm was not long enough to go over the 29 inch wheel. The ability to buy just this part is great, rather than having to buy a completely new rack. Install time was about 5 minutes tops. Simply unscrew the tire hook from the old arm and place it on the new arm. Two allen head bolts connect it to the rack and your done. Very quick shipping as well. Thanks


This replacement arm is a couple of inches longer than my older ratchet arms and is a must have when carrying a fat bike on the rack. It will work well when combined with the new fat bike trays but is a very tight fit with bikes that have the new Bluto suspension fork. It appears the fork and arm will rub on each other during transport. I believe this arm will work when I put 29+ wheels and tires on my fat bike as well. New nuts and bolts with the arm would be nice.


The clamp was vandalized during a probable attempted theft mid vacation. I had the newer cable style lock delivered express by It arrived a business day ahead of schedule well packed. It was quickly installed and fit my Thule classic platform style as expected. I discovered that the key cylinder could be removed from the old style track lock and inserted into the cable lock, so I could retain my old keys for the time being and continue with the planned trip. Thanks for the great service.


I bought the Replacement Locking Ratchet Arm Assembly for T2 Bike Carriers because I got a 29er MTB and the original arms weren't long enough to fit over my front tire. These fit well for my 29er and have done a great job over the last year. No complaints


Fits the original T2, but you can tell the arm and ratchet mechanism are not as robust as the original equipment (Thule must have changed the parts when they released the T2 Pro). One of the arms (bought two) had a paint chip in it from shipping. Also, keep in mind this part does not include the clamp that fits over the bike wheel. That is a separate part.


This arm is the perfect replacement for the original Thule T2 to add extended length for 29" wheels. It also adds the locking mechanism to keep honest people honest. has once again come through with exceptional service getting this items shipped right away as well as keeping me informed with communication emails on the order and shipping. etrailer is a company all online companies should model their customer service after...they are that good at what they do!


Everything exactly as I expected. High quality product and service. I bought a new bike with 29" wheels and didn't realize that the larger wheels didn't fit in the older rack arms as well. Noticed I had a problem when bike fell over in rack while I was driving on freeway! Fortunately bike didn't fall out of rack so it wasn't damaged but I new I had to do something fast before I had a bigger problem.

Would highly recommend eTrailer for all like transactions.
