Being the cost-conscious (or cheap bastard, whichever you prefer) cyclist that I am, I could not justify spending $15 on a piece of neoprene and velcro to keep my chainstay paint looking good. I also didn't like the giant inner tube wrapped around the chainstay and zip tied into place every couple of inches.
Enter my creation, the lightweight zip tie/ tape free inner tube guard. Its easy and cost is $0 if you've got an old inner tube lying around like most cyclists do. Bonus frugal points if the inner tube you use is covered in patches.
Start with a bare chainstay. Cut an inner tube lengthwise about an inch wide. Some tubes even have lines on them to aid you in cutting straight.
Now place the end of the tube across the chainstay and begin wrapping over itself around the chainstay. See photo.
Wrap the inner tube around the chainstay in a uniform fashion. When you near the end place a flat object against the chainstay and wrap the tube tightly over it.
Trim the tube to length and stuff it behind the flat object.
Slowly remove the flat object keeping the inner tube uniform. Then remove the tool used for stuffing. Viola. You now have a $0 DIY chainstay protector with no zip ties, tape, glue, etc. Looks mighty fine too.
