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..

Replaces the lockable ratchet arm for your Thule T2 bike rack (TH916XTR or TH917XTR). Lock cores are sold separately.


I bought a mountain bike and my current thule ratchet arms on my bike rack did not fit over my bike's 29" wheels. Thankfully I found etrailer and all the helpful reviews that other people bought this arm to fit over their mountain bike tires. I bought one arm to test it out. It was super easy to install! I'm going to order an additional arm for my two bike rack and the thule lock core system to install as well! Thanks etrailer and everyone who left reviews! Very helpful all around and it helped me save money from buying a brand new bike rack! Thanks!!


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!


I believe your customer service communication is really, really superior to other companies. Solid follow-up before shipping, during, and post delivery. I would definnately recommend etrailer! Great Job and thanks for being a breath of fresh air in the Client Relations world!
FYI ... installed all the parts and my Thule T2 is back up and working as designed! Thank you etrailer my new retailor!


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.


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


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.

Glad to hear that you are getting good use out of your bike rack! Thule actually redesigned the T2 bike rack and made improvements to the tilting/folding mechanism as well as the anti-rattle device. You can find the various configurations at the link provided as well as review videos for each of the bike racks on their product pages.


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.


Needed to upgrade my old T2 Classic for 29" bike. This replacement arm work perfectly!


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 and the Replacement 10-32 Nylon Locknut # 853-5973. 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 Washer # 951081654, and Replacement Bearing Clamp for Thule Sidearm # 753-3591 (no longer available). If there are other replacement parts you need just let us know!


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.


Arrived quickly and was easy to install. Now my old Thule T2 will fit my new 29” MTB.


After a brief phone call, I was certain that I was going to receive the correct part. The two ratchet arms for my bike rack was exactly what I needed. Lauren was extremely helpful!!
Thanks again for your efforts


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.


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.


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.





Have an old SportsWorks Rack and I love it... built out of steel and like a tank. The ratcheting arms were wearing out after a decade of use. These replacement arms were just what I needed!



Hey Erich i was planning on also getting this part too for my sportworks t2 rack. Did you do any modification to make it fit the old rack?? Any info helps. Thanks in advance.Jeff


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.


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.


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


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.


Had to replace swing/lockarm and tray after someone hit my car. :(
etrailer had the parts in stock...and started processing and shipping over the weekend! This was a NICE surprise! This is the one with the integrated lock cable replacing a non cable style and fits any T2 perfectly.


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 upgraded my bikes from 26ers to 29ers.... So glad to be able to update my Thule bike rack with these parts with out having to buy a new rack!!! Great prices!!! Installation/replacement was a breeze!


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!


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.

  • What is the Overall Length of the Thule T2 Replacement Ratcheting Arm # 752-1272-001
    I went out to the warehouse and pulled a replacement arm for T2 bike racks, # 752-1272-001, to measure it. The measurement I came up with from the center of the pivot end to the end with the lock was about 30-1/2 inches. Overall length is 31-1/2 inches. These measurements should be more in line with the original arm.

  • Why Doesnt Thule T2 Classic Come with Cable Locks
    The Thule T2 Classic does not have a cable lock since the arms have locks built into them and the shank of the rack has a lock to secure it to the hitch of the vehicle. There is a replacement arm that will give you a cable lock though. For that we had a customer come back and state that the part # 752-1272-001 gave them the ability to use a cable lock.

  • Purpose of Integrated Cable Lock in Replacement Locking Ratchet Arm Assembly for T2 Bike Carriers
    One of the features of the Replacement Locking Ratchet Arm Assembly for T2 Bike Carriers, # 752-1272-001, which you referenced, is the integrated cable lock which provides extra security for your bike. It retracts inside the upright post. You simply pull out the cable, and feed it through the frame of your bike. The cable comes back around into the plastic housing. A lock core secures the cable to the plastic housing. Check out the linked video which shows how this cable lock is used.

  • Can Longer Arm Be Installed on Thule T2 Classic for Larger Bike Tire
    As long as you have the pre 2012 version of the Thule T2 Classic bike rack then yes, the Replacement Locking Ratchet Arm Assembly # 752-1272-001 will allow you to carry 29" tires on your bike (see attached photo customer sent in). If your Trek E-Bike has different sized tires then we'll need to look into a different solution. Attached is a review video of the replacement arm for you to check out.

    I made a short video with a basic overview of how to insert a lock and then lock the arms on a Thule T2 bike rack like # TH916XTR. If you have followed this method and the arms still moves freely when it should be locked then there is a problem inside the unit and the arm should be replaced.

  • Replacement Arm For Thule T2 Classic Bike Rack
    I can definitely understand not wanting to buy the whole arm if you don't have to, though I checked directly with Thule and the lever on the arm assembly is not available as a separate part, so to replace that you will need to replace the entire arm. I verified with Thule the correct replacement arm for your Thule T2 Classic bike rack is the following: - Replacement Non-Locking Ratchet Arm Assembly # 753357902

  • Parts Needed to Replace an Arm on a Thule T2 Trailer Hitch Mount Bike Rack
    First, you would need the arm itself, # 752-1272-001, that you have referenced. Then you would just need the hook portion, # 753-3583. That should be all that you need to replace one arm on a Thule T2 bike rack.

  • Replacement Ratchet Arm Assembly for Older Thule T2 Hitch Bike Rack
    I spoke with my contact at Thule regarding the Locking Ratchet Arm Assembly # 753-3579 referenced in your question. He stated that it does not appear that the replacement part has had any recent upgrades, but it will also depend on which particular model T2 you currently have as to whether or not this will be compatible. This ratchet arm is designed for older Thule T2 hitch bike racks TH916, TH916XT, TH917 and TH917XT. I did also go out to the warehouse to take a look at this part and measured...

  • Replacement Thule T2 Ratchet Arm Assembly Compatibility with Wide Fork
    The Replacement Locking Ratchet Arm Assembly for T2 Bike Carriers # 752-1272-001 is about 1-1/2 inches longer than the original T2. This helps especially with Fat Bike Tires. I can only assume that it will eliminate your fork contact issue without knowing your bike as obviously fat bike tires require a wider fork as well. This arm also has the integrated cable lock so you may want to get the lock cores # TH450200 to take advantage of that feature.

  • Should Replacement Thule T2 Bike Rack Arm be Lubricated Before Installation
    The first thing you will want to do is clean off the dirty areas you mentioned. You will want to avoid spray lubricants like WD40 because they can attract dirt and clog up the works. Some light grease such as LubriMatic White Lithium grease in 14 oz. Cartridges # L11354 will work fine. Grease isn't a necessity, but you can use it.

  • Recommended Locking Ratchet Arm Assembly For T2 Bike Carrier
    I called my contact at Thule and explained the problem you said you were having with your fat bike. They told me that you may have an older model T2 bike carrier. If you do not have the cable at the top of the wheel arm you have the older model and it will not fit over the wheel. I do have good news though. We offer a replacement arm that is longer and is designed to fit bikes with a wheelbase up to 29 inches. You just need to order part # 752-1272-001. This will install on your T2 bike...

There is a longer one, # 752-1272-001, which is 31-1/2 inches long overall which is about 2 inches longer than the original. It has been reported to fit the original T2 (916 or 917) but I cannot verify that.
