My lowepro roller wheels have seen better days and after years of use they needed to be changed. The rubber part was coming off the wheels. I researched online and found this website.
I also contacted Lowepro as they have a lifetime Warranty on the pro roller cases but the wheels are part of normal wear and tear and are not included. So I search also for the parts to buy separately from Amazon etc...And found that Joel Spring's kit on Ebay was the easiest and best solution and price wise a great option considering the ProRoller cases are not cheap to just replace for 2 wheels! So here is my experience in picture, before and after!
