I was restoring my Moulton F frame, and I was trying to dismantle the front fork suspension. It was so rusty and old, so I used a hammer to take it out. It finally came out, but the problem is that I somehow broke the nylon bearing on the top of the fork. I am trying to find a replacement, but I cannot find any same part for sale. The only option was buying a whole fork for parts. However, the cost is way over my budget and paying around 300$ for one bearing is unreasonable. I am considering to order 3d printed one with nylon material, but I don’t know if it is a good idea. I want to find a cheap alternative, like using a nylon ring. Please leave your suggestion!
