Oversized Cam-Lock®

Our regular Cam-Lock® hooks work perfectly with diameters of 15mm or less. We also have the Oversized Cam-Lock® that works with rack tubing diameters of 15mm up to 21mm. Simply follow the instructions below.

My rack tubing diameter is 15mm to 21mm

  1. Click here to add the Oversized Cam-Lock to your cart.
  2. We will adapt your pannier. In other words, an Arkel staff member will switch the regular Cam-Lock with the Oversized Cam-Lock on your bike. The regular Cam-Lock will also be sent along with you, in case you change racks in the future.
  3. Once your receive your pannier, there is no extra installation required by you. Simply put the bag on your rack, hop on the saddle and ride on!

I don't know my rack tubing diameter

If you’ve just read the title and don’t understand a word of it, you’re not the only one. The cycling world can get quite technical sometimes, but we’re here to help you out. Before we go any further, we will need you to measure your rack tubing. We have a step by step tutorial below.

How to Measure your Rack Tubing

1. Get a pen/pencil, a ruler/measuring tape and a strip of paper.

2. Wrap the strip of paper around a section (circumference) of your rack tubing.

3. Mark the paper at the overlap.

4. Measure from the edge of paper to the mark.

5. Locate your measurement in the table and click on it for further instructions.

Unfortunately, your rack tubing is too thin for our Cam-Lock®. In other words, all of our bike panniers are not compatible with your current setup. If you’re interested in changing your rack with one that is compatible with the Cam-Lock®, feel free to check out our Rack Fit Guide for rack recommendations.
