This is the Dunlop Aerogel Rush squash racket. It’s an older model that’s targeted towards doubles players.
I’m posting about it because I’ve seen it crop up a couple times recently. I first learned about from from Clarke on Twitter.
I’ve also seen from my Amazon reports than a few people have ended up buying this racket after visiting my site, even though I’ve never posted about it. So it must be a popular one or a favorite that people are looking for.
The manufacturer’s description says this is head heavy and weighs in at 167 grams (strung), which makes sense for a doubles racket. Anyway the racket has been discontinued but it is still available on Amazon.
