Topeak Extra Long Rack Mounting Bracket – 34.5 cm Extension Arm for BabySeat II and MTX Tubular Racks – Durable Steel Construction for Small Bike Frames – Improves Rack Stability and Fit

Worked perfectly on my recumbent trike! Just the right length to connect my Blackburn bike rack to the seat stays on my TerraTrike. They have just enough give to allow them to be bent into position for proper attachment. The hardware included seemed to be decent quality. I did need to get some extra bolts/nuts for my install though due to my bike being "unique".

The original brackets that came with the basket were too short to allow the basket to fit behind the seat on my bike. These were the perfect fit and work just great. Now I can have my basket clipped on the back of my bike and still be able to sit on my bike seat.

Heavier than many others. Worked well to level rear bicycle racks that had shorter mounts.

I purchased a new bike for my wife and the old brackets were too short. Her basket would have crashed into her seat. These did the trick. They are extremely sturdy. They were easy to install and are adjustable for all your needs. They are very light weight but very strong.

Sorely disappointed when I found the arms included in the bike rack were too short to properly fit my bike rack. I have an XS frame and after reading lots of reviewed found others who have xs or small bikes had the same prblm. This solved the prblm. I am annoyed I had to purchase this tho. Personally I think it's too expensive for 2 pieces of metal. The bike rack should've came with different length arms so I didn't have to purchase this separately. Brought the overall cost of bike rack way over what I wanted to spend. Easy to install and bend my hand. Came with way more screws and washers than I needed.

Worked great!

Ok, so this is a pretty simple item, right? But, often the simplest of things can be the worst quality. These two rails and supplied hardware were excellent quality and were a joy to install. And I’m sure they’ll last longer than the bike I put them on. So glad I went with the Topeka brand instead of the slightly cheaper no-name. Also, despite the description, these appear to be stainless steel.

Wanted to mount bike rack on my folding bike this worked out to be perfect.

Exactly what I need to keep a Raleigh child seat on my bike. The manufacture rack came short in some bike model, especially small frame bike

Bought as OHs bike has 29” wheels on a smaller frame (she’s a short ar*e) and mounting lugs were a way down the seat post so struts provided with the pannier were slightly too short. These solved that problem perfectly. Just the job!

Die Halter haben gut gepasst. Gut fand ich auch, dass genug und passende Befestigungsschrauben dabei waren

Just what I needed, easy to install.

These are aluminium (Not magnetic) and not steel as someone suggested so will not rust. I had to flatten out the twist as I needed a straight bracket but they fitting my Topeak rack perfectly to stop it moving sideways with the luggage on.
