not the lightest, but if you are having problems with your tubes flatting from the inside of your wheels (not tire punctures but ribbing expanding into spoke holes).
This stuff will fix it!
I keep extra rolls of it in in lots of sizes because it is so handy, after a few years of riding a new wheelset, you will need this stuff.
Tried to install latex tubes with OEM rim tape, but that was not successful. Talked with customer service and their recommendation was to use Velox Rim strip.
Received it a few days latter, installed on the wheels in a snap. Problem solved, tubes are doing well and love the ride.
Some easy to use tube insurance. I applied this ribbon of cloth tape to Mavic Ksyrium Elite rim on my '07 Jamis Supernova. Never'd used tape on these rims previously and thought it couldn't hurt. Sticky-side sticks as expected, width just fine for the application.
The two bikes I purchased for strengthening my arthritic knee came with a very light weight rubbery plastic rim strip which I knew in time would cause a tube to blow out. And because like most bicyclists, I do not enjoy needlessly repairing flats or replacing tubes, I got the Velox rim strip to replace the factory strip. Velox really shouldn't be called a strip, but a cloth tape, and the cloth is very heavy and it has a strong adhesive, so once installed, it isn't going to move.
This is one of the best rim tapes on the market. I have been using it for years as my go to tape. I work on many of the bikes in my club and always keep a couple of extra rolls on hand. I have seen many other brands of tape roll or slip out of place. I replace it with this tape and know I will never have a problem with it ever again.
I bought the white rim tape as suggested by the sales person at their on-site store. The white tape allows better visibility of the position of the tube within the rim when fixing a flat to help eliminate pinched tubes. It was a great suggestion. The rim tape was easy to install.
