Wilson RF7 Grommets alternative?

I have a prostaff RF 97 autograph, the latest version that's in red and black, which needs new grommets, These seem impossible to find. Are there any other grommets that can be used instead? This is my favourite racquet and I will play until it eventually cracks. I have a newer tuxedo version, but this plays completely different from the red, even after trying to balance and modify with weights (feels more head heavy).

Wilson Pro Staff 97 & RF97 Grommet (2016) may fit. Unfortunately TW won't have them until Sept 9. @TW Staff - any updates?

If you can't wait that long, then you have to search online using Google. If you do so, be very specific as to what you want including model year.

Yes, it is the 2016 model, thanks. I can wait until Sept 9. Perhaps my racquet was a bit under spec., and that's why it's so hard finding a newer version that feels similar... I had a v11 also, it was a bit more similar, just a little heavier, but it cracked unfortunately.

You need to measure the mass, balance, SW etc of your favorite frame. Then try to match your 2nd one to those same specs or to a common set of specs. To make a frame less massive depends on what needs to be changed. Too HH, use a heavier grip or lead. Or if too HL, add lead to the hoop. To reduce mass in the hoop, you can trim the sides of the bumper guard. You can drill a bunch of 3 mm holes in the bumper guard. You can sand paint off the tip of the hoop because the mass of paint is NOT negligible.

Yes, I did (except the SW). Most noticably It was too head heavy. I put silicone and some lead in the handle. Even though I have the weight and balance and strings matched it still feels differently, unfortunately. I don't have a SW machine and I don't trust the SW app (SwingTool).

SW app just automates the counting of the swings so that it is much more accurate than using a stopwatch. Measuring hang point, balance point, mass and timing the swing times uses exactly the same formulas used by TWU. Being off in measuring all the input varies the resultant SW (Kg-cm² note the exponent on cm.) Just putting silicone in the handle is not a good idea for matching balance. I would have used lead tape because it is much more easy to remove. You may need to search for a pro shop near you with a SW measuring device like an RDC or Accuswing. If you elect this option, do it with bare frames because it is easier to mod them to spec. TWU has a frame modifier app that is precise and accurate based on input. If you measure strung frames with OG, leather grips, you just wasted your $ since those items affect balance etc. [I did mention that you can drill out a new bumper guard if you are a DIYer]

The current RF97 grommets should fit all versions of the RF97. Actually until the PS97v13, both the RF97 and PS 97 took the same grommets--the changed pattern on the v13 requires its own grommet strip (i.e., no longer the same). Good luck.

Thanks for all replies. Drilling holes in the bumper guard is interesting,never tried that… I used silicon because it’s easy and fits and sticks inside the handle without moving parts. On a side note I tried switching racquet to a Yonex Vcore pro HD. Love the racquet, great for my BHs. What’s perhaps lacking compared to prostaff is the stability when returning serves. I think I can get used to this however, or add some weight to the butt cap.

I just wanted to show you guys what my grommet swap looks like. I swapped the v13 grommets onto my 2015 RF97. The grommets were very easy to put in, everything went smoothly. You can see from the pics, the side grommets are a little bit different and rise up higher. So if you are not picky, the the v13 grommets fit he older RFs

Thanks! I just got my replacement grommet parts and will try to do the same as soon as my new stringing machine comes. What tools did you use/have to use to change your grommets?

^^^All you should need is an awl to center each grommet in the racquet hole. The sides are super easy. The headguard part is a little more challenging but the RF is pretty easy as compared to other racquets. My technique is to flex the headguard in my hand for a minute or so and then I start the headguard on one side on a firm surface (like a stone countertop)--once it get it started I then roll the racquet slowly with medium pressure over the hard surface while setting each grommet from inside the frame with the awl--DO NOT push too hard if the grommet is not set or you will crush the grommet and the strip will be ruined. Take your time. Good luck.

Yes the RF grommets are probably the easiest for me to change. I like how the grommet holes in the head guard do not deform too much after stringing. It’s allowed me to take the head guard off and on multiple times while adjusting the amount of lead tape underneath.

When installing the head guard, I actually start from the center and then go left and right. But either way seems to work.

I replaced my grommets with the RF v.13. Guiding the grommets with an awl was pretty easy. When weighing my old worn out bumper guard I found it to be 7g, compared to 10 g of the new, so it will affect the balance slightly. I did my first string job also, with rpm power blue 1.25. 90 minutes .
