Anyone here use protective tape to protect a new frame? To which areas do you apply the tape? I have a new frame and I am worried that other bikes sharing bike racks will scratch my ride.
I use helicopter tape. You can find it on Amazon or from most any race car supply shop. It's a little pricey but well worth it. It's very sticky and thick enough to absorb impacts from rocks. I use it on the bottom side of my downtube, on the drive side chain stay, and anywhere a cable is close to the frame.
A protective covering is useful on the chainstay if it is prone to frequent chainslap. Other than that, I'd say that it is worse to try to protect your frame with tape than to just allow it to get an occasional nick and scuff.
On a practical note, if you do get some paint chip on a steel frame it is a good idea to dab a little clear nail polish on it to prevent rust from getting started.
Finally, if the frame is worth it, you can always have it professionally powder-coated when the time comes. It is like having a new bike.
Pieces of old inner tubes secured with painter's or electrician's tape. Roll a few lengths of inner tube around the toptube as needed. Also wrap innertube around your D lock to prevent scratches, or just keep some handy where you carry your good spare inner tube.
You can buy clear tape meant to fit your bike, or you can save some cash and fit some clear packing tape on the areas that are scratched the most.
