Lead tape beneath the bumperguard

Q: I have been reading on some on-line tennis message boards that top players add lead tape under the bumperguard or grommet strip so that it can’t be seen. How is this done?

A: Adding lead tape beneath the bumperguard or grommet strip is an advanced technique. You have to strip the frame to do the modifications, which means either that you must have replacement grommet kits on hand, or the racquets must be brand new so the existing bumperguard and grommets can be lifted to allow installation of the lead tape, and then reinstalled. Some new grommet kits are flared from the factory, which means that even when working with new racquets, you will need to replace the bumperguard and grommet kit. Also, not every bumperguard is going to have much space underneath it for lead tape, or anything else except some clay dust. Finally, making alterations means you have to strip the racquet again of the bumperguard and grommet strip, if you wish to remove lead tape or conceal additional tape.

To start, strip each frame piece by piece, measuring weight, balance, and swingweight every step of the way. Then calculate how much lead tape you need to add beneath the bumperguard and/or grommet strip (USRSA members can use the on-line tools at RacquetTECH.com), and see if there is even room for that much tape. Cut the tape into pieces (or strips) small enough to be hidden by the grommets or bumperguard. Once you have each of your bare frames the same, reassemble them and recheck the specs. This type of modification is a lot of work, but it is rarely called for except when you’re dealing with top touring pros. If you’re going to attempt it, we recommend that you first make certain that each racquet to be matched has the same flex.
