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.
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.
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.
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.
I bought this tape because my hybrid rims came with a flimsy rubber rim strip the stretched and let the tube enter the spoke holes and pop. I got the 22mm width which was a tad too wide for my hybrid rims, but it doesn't interfere with the bead. I've rised the pressure more with these to 100psi, no signs of ever failing! This rim tape is a must for any tire with deep spokeholes in aero rims, or anybody tired of inferior rim tape popping tubes.
Velox has been THE rimstrip since.. well, I'm dating myself - but despite all the newer plastic alternatives it's still the one I can trust. I've had the slip on plastic ones move around on me and cause a flat more than once. To be fair, the Schwalbe rimstrips seem pretty reliable but you just can't beat the security of the Velox product.
Plus there's a certain vintage cool to a cloth strip, especially one made in France. Even if it's only you that knows its there.
I use this brand in all my wheels, road and MTB (two sizes available), and have been using it for decades. Other cloth tapes fail over the holes on double wall wheels where this protects the tube forever. The adhesive is fantastic. The cloth is thick. There is even a little extra length if you want to trim it to give equal thickness on both side of your air valve. I've tried others and this is the best.
