Callaway Lightens Up with Ultra-Premium GBB Epic Star Line



Callaway’s new Epic Star line targets golfers seeking maximum distance from lighter golf clubs: think seniors, juniors, women, and other slow-swingers.

The new drivers, fairway woods, hybrids, and irons incorporate the same technologies as Callaway’s flagship Epic products, but they’ve have been lightened up with head design tweaks and lightweight, ultra-premium components to help golfers hit higher, faster, and longer shots.

The new clubs are available for preorder on September 22 and in stores September 29. Learn more about each of them below.

GBB Epic Star Driver and Fairway Woods


Callaway’s Epic Star Driver (12 degrees).

The Epic Star driver is an import to the U.S. market, where the lightweight driver is the No. 1 seller in Japan. Its Japan-inspired theme continues through the shaft and grip. The stock shaft is an ultra-premium, 39-gram Mitsubishi Grand Bassara shaft that’s made at Mitsubishi’s renowned Japan facility. The driver also comes with a Golf Pride J200 grip that was also designed for the Japan market. It has a smaller diameter than standard grips, helping it tip the scales at a mere 41 grams.


“There are pockets in the U.S. with some [golfers] who are looking for a premium experience with Epic, but in a more lightweight package,” says Callaway Brand Manager David Neville.


Like Callaway’s GBB Epic driver, the Epic Star (available in lofts of 10 and 12 degrees) includes the company’s Jailbreak technology, two titanium bars located behind the club face that stabilize the crown and sole to improve energy transfer at impact. The new driver also uses the company’s extremely lightweight crown and sole construction, highlighted by its 9.7-gram triaxial carbon crown.


The Epic Star is different in two important places, however, starting with its sliding rear weight that weighs just 11 grams — that’s seven grams lighter than the GBB Epic’s sliding weight. Callaway also saved seven grams from the driver by shifting to a fixed-hosel design, allowing the club head to weigh just 190.3 grams. The total weight of the driver is a mere 286 grams, making it Callaway’s lightest driver in history.


The Epic Star fairway woods (available in 15, 18 and 21 degrees) also have a fixed-hosel design to reduce clubhead weight. Their Mitsubishi Grand Bassara shafts weigh in at just 49 grams.

The GBB Epic Star driver will sell for $699. The GBB Epic Star fairway woods will sell for $399.

Epic Star Hybrids and Irons

Callaway’s new Epic Star hybrids are available in three lofts (18, 20 and 23 degrees), and like Callaway’s Epic hybrids, they bring golfers more distance by way of 455 Carpenter Steel Face Cups and an ultra-light, carbon triaxial crown. They also have a center of gravity (CG) that’s concentrated low and deep in the club heads via a metal-injection molded process (MIM) and a tungsten-infused standing wave. This technology, combined with their 50-gram, Mitsubishi Grand Bassara shafts, helps golfers send their hybrid shots higher and farther down the fairway or toward the green.


The new Epic Star irons come stock with 55-gram Mitsubishi Rayon Grand Bassara shafts, as well as a Black PVD finish that gives the irons a sleek look at address. They’re available in 4-9, PW, GW, and SW.


Like Callaway’s Epic irons, the GBB Epic Star irons showcase a 360-degree Face Cup design that measures just 1 millimeters at its thinnest point to help golfers maximize distance and forgiveness. They also share the company’s Exo-Cage design, a lightweight, steel framework that provides rigidity to help the irons deliver more ball speed at impact.

“There’s kind of a lighter, longer, stronger spec in order to maximize distance,” says Luke Williams, Senior Director of Global Product Strategy for Irons and Putters. “We’ve seen that there’s sort of an emerging category here and an emerging segment in certain players that really are looking for this type of product. So while this isn’t a broad offering for us — it’s a really targeting offering — there is a market.”


In conjunction, a hollow-hosel design helped Callaway engineers shift more weight toward the center of the Epic Star iron heads to provide a better feel and optimize the launch conditions of each iron. In the long irons, the CG is positioned lower in the club heads to improve distance. In the short irons, the CG is positioned higher in the club heads to improve trajectory control. According to Callaway, each of the irons are close to achieving the USGA’s legal limit on COR, or coefficient of restitution, a measure of ball speed retention.


The Epic Star hybrids will sell for $299 each, while the Epic Star irons will sell for $300 each, or $2,400 for an eight-piece set.

    New gear from Callaway, gee it must be at least a month since they promised we could win everything with there last offering. Might wait another month to see what changes the world and then there’s Christmas. Old Mr Callaway would be so dissapointed at these cowboys

    I am not a slow swinger (108 mph swing speed with the driver) so 7 years ago I bought the Taylormade Superfast TP Burner driver at 284 grams. Then I removed the 50 gram grip and installed a 25 gram grip. Sucker swings fast. Still have it. Still outdrive everyone in my foursome by 25 – 60 yards, averaging 265 to 295 (300 downhill, downwind, firm ground :)). But I will be checking out this new, lightweight, Epic Star. If you put a good swing on it a lightweight club will go… and go… and go…

    Looks like the big OEMs are concentrating their marketing to the upper 1% where price doesn’t matter, and neither does performance because rich guys are mostly incompetent. Their personal clubs are only for show and status symbols.
    An $800 driver is equivalent to $8 for a multi-millionaire….. and a $3000 set of clubs is like $30….. and a $100,000 car is like $1,000 ….. get the drift? And that’s the market the golf OEMs are targeting with their new offerings because multi-millionaires are bigger suckers for glitzy clubs.

    If you have a slow (<90 mph) swing speed and dropping yearly, equipment will not compensate significantly to restore speed. Your aging body just can't put out any more swing speed effort and if you believe an $800 "driviagra" will rejuvenate you, you are clinging to hope based on fantasy.
    Just buy a simple economical driver with extra face loft and that is the only prescription for retaining distance. Of course if you want to send your money to Japan ……

    • James

      Sep 12, 2017 at 3:15 pm

      Have you seen any testing with XXIO? Keep holding onto that idea that equipment won’t effect distance as your swing speed slows.

      • XO

        Sep 12, 2017 at 5:59 pm

        No I have not seen any testing with XXIO clubs and I just don’t trust manufacturers data on their own clubs. I have read the many promises made by the company here:
        …. but I am still dubious. If you are with XXIO send me a set of forged clubs and I will test them for you.

        As they age they will see things differently, unless they are the old guys who still think they drive it 290 when it’s closer to 150.

    So you are getting a lighter Epic with a $450-500 aftermarket shaft in the driver. I own that shaft – in R Flex, it is 43g and is incredibly stable with a smooth kick. If you are using a 60g shaft, you may pick up 2-3 mph in this shaft.

    The issue is whether a liteweight shaft fits you – if you are a 70-90 mph speed with a smooth transition, odds are you will like it if you can get sufficient clubhead feel – swingweight D2 or so – to get a consistently high smash factor. Like any other club, get fit.

    I think it’s a club for the 55+ club who don’t have the greatest swing and just want to play, and range time is not play time.

    • GB

      Sep 12, 2017 at 1:27 pm

      U will only have a stable shaft with this 39gram Bassara if the driver head weighs very little. 190 grams is still on the heavy side, so I’m surprised that Callaway didn’t go sub 180gram, as this shaft will bend a lot because of that 190 weight and might make the ball spin too much. But to put that Epic head on it, this is as much as they could have done. And they didn’t want to put a heavier grip on, obviously, nor shorten the club.

    • James

      Sep 12, 2017 at 3:19 pm

      Anyone who thinks that you’re getting the $500 Grand Bassara is greatly mistaken. Please look at the link and tell me where there are the 49 gram wood options and any resemblance of an iron shaft with Grand Bassara name. You also do not own a 43 gram Grand Bassara shaft. You may own the GG or P Series, but not the Grand Bassara.

      That’s wrx for ya! The owners and staff get free equipment plus they get invited to all the corporate outings. Of course they’re more than willing to run these ads. Don’t bite the hand that feeds you. And believe me, these guys are fed well!

    Callaway will be going the way of TaylorMade sooner than most think (holding company). Laughable price tag and product strategy.

    I see the Epic Star line more of a competitor to the XXIO Prime line of clubs rather than PXG.

      I have an 85 mph swing speed and launch the ball over 250 yards carry. My Smash Factor is 1.65 !

      • Kym

        Sep 28, 2017 at 12:44 pm

        A Smash Factor of 1.65 when only 1.50 is possible. You should perhaps do your homework before posting such a non-sensical comment

        • Kym

          Sep 29, 2017 at 11:32 am

          Further if we take your Club Speed of 85 mph, even on your best day you will only see 229 Carry (Club Speed X 2.7)

          With an impossible Smash Factor of 1.65 and a Swing Speed of 85 the Ball Speed would be approaching 140+ which is very unlikely with a Club Speed of 85

    $800 driver, $300 each iron. Laughable. Heads should roll at Callaway for this strategy. I’m pretty sure they’ve misread the market….

    • Swingman/Jerry

      Sep 12, 2017 at 12:10 pm

      You can always pull the shaft and re-use it – it is a great shaft for the market it fits and its aftermarket price is $450.

  22. Scott

    Sep 12, 2017 at 8:06 am

    $800 driver!? Bye

    • Shadow

      Sep 12, 2017 at 8:56 am

      Agree bye! Geeze you really getting ripped off in the US with this driver. First of all it comes in 10.5 & 12*. The 12* is not even offered in Japan. Overall you are getting a recoloured driver from Japan. The grip mentioned, not even stock or an option in Japan – I cant find it here in Japan. The bassara shaft is just a one off option in customisation for Japan. They don’t even make this driver/shaft combination to buy off the rack!

      The stock offering in Japan is 9.5 & 10.5*. The stock or base model Epic star weighs 289grams just 3 grams more than the US version. Stock shaft is 49grams. The Bassara in Japan also comes in 32.5 & 35.5 grams. The “speeder” option shafts come in weights of 29.5, 33 & 35.5 gram options.

      Save yourself money and buy the stock Japan version through Rakuten @ about US$450.

      For US$799 I would look at the GBB Epic Forged driver direct from Japan.
