Are OnCore golf balls any good?

The performance data says yes, the quality data says check your dozen. Golf Monthly measured the VERO X2 at 6,895 rpm on wedges, roughly 200 rpm under a Pro V1x, and Plugged In Golf found the ELIXR's full-wedge spin within a few hundred rpm of premium tour balls. The caveat comes from Ball Lab, which has cut the ELIXR open twice. Its 2020 teardown of the original flagged 14 percent of the sample for concentricity problems, and its 2023 teardown of the current 350-dimple ball flagged five of 36, two of which weren't ELIXRs at all.

What is the difference between the OnCore VERO X1 and VERO X2?

Compression, and that's mostly it. Both are 4-piece cast-urethane balls at $40 a dozen with the same metal-infused mantle. OnCore rates the X1 at 85 and the X2 at 95, so the X1 suits the 90–105 mph band and the X2 wants 105 mph and up. Plugged In Golf described the X2 as markedly firmer than the ELIXR with strong greenside response; Golf Monthly noted it should be the firmest of OnCore's three balls at the time. Pick by swing speed.

Do OnCore golf balls still have a metal core?

No. The hollow-steel-core lineage ran from the MA 1.0 in 2014 through the Caliber in 2016, and both are discontinued. Current OnCore balls chase the same perimeter-weighting goal through the mantle instead: the VERO X1 and X2 use a metal-infused mantle layer, and the VERO XP1 uses a dense metal-injection-molded mantle that OnCore says raises moment of inertia by 25 percent. The ELIXR uses a polymer mantle with no metal at all.

What swing speed do you need for an OnCore VERO X2?

About 105 mph and up. The X2's 95 compression is the firmest ball OnCore sells, and it feels firm at moderate speeds. TrackMan's amateur data puts the average male driver near 94 mph, which sits below the X2's window and inside the ELIXR and VERO X1 band at 84 and 85 compression. If you're under 100 mph and reaching for the X2 because it's the tour ball, that's the mistake worth avoiding.

Where are OnCore golf balls made?

Taiwan, mostly, through contract manufacturers rather than an in-house plant. Ball Lab identified Foremost in Taiwan as the factory for the original ELIXR and both VERO models, and reported that the enhanced 350-dimple ELIXR came from Launch Technologies, also in Taiwan. Foremost also builds urethane balls for Vice and Maxfli, which is part of why the value-tier urethane balls perform so similarly. OnCore designs and specs the balls from Buffalo, New York; it doesn't mold them.

What happened to the OnCore GENiUS ball?

The tee-to-green version still hasn't shipped, nine years after the concept went public in 2017. The original pitch was a GPS-equipped ball reporting location, speed, flight, and spin. By 2023 that had become the i-Roll putting and wedge ball using onboard sensors and Bluetooth instead of GPS, partly because a metal shell blocks GPS signal. A putting-only GENIUS ball debuted at the January 2026 PGA Show at $240 for three balls, a case, and a year of the app, with shipments planned for Q2 2026. OnCore's technology page still lists the tee-to-green version as coming soon.

OnCore Golf Balls: The Complete Lineup and Buyer's Guide (2026)

Q: Is the OnCore ELIXR worth it compared to a Pro V1?

It's about half the price for most of the performance, which is the whole direct-to-consumer pitch. The ELIXR lists at $30 a dozen against the Titleist Pro V1's $57.99. Plugged In Golf measured the enhanced ELIXR's driver spin under 5 percent below the reviewer's own tour ball, with half- and full-wedge spin within a few hundred rpm of premium balls. What you give up is manufacturing consistency (Ball Lab flagged five bad balls in 36 on the current ELIXR in 2023) and the tour validation Titleist has and OnCore doesn't.

Quick answer

OnCore sells five balls built around one idea: push mass toward the outside of the ball. The tour tier runs the VERO X2 (95 compression, $40) and VERO X1 (85, $40), with the newer VERO XP1 (85, $44.99) on top. The ELIXR (~84) is the value-urethane pick at $30, about half a Pro V1. The 2-piece AVANT 55 anchors the bottom at $20. Independent spin numbers land close to tour balls; the manufacturing consistency data is the weak spot.

OnCore golf ball lineup at a glance

Model	Cover	Compression	Layers	Best for	MSRP/dozen
OnCore VERO XP1	Cast urethane	85	3	95–105 mph, highest-MOI build	$44.99
OnCore VERO X2	Cast urethane	95	4	105+ mph, firm feel, max greenside grab	$40
OnCore VERO X1	Cast urethane	85	4	90–105 mph, softer tour feel	$40
OnCore ELIXR	Urethane	~84 (mid)	3	90–105 mph, value tour ball	$30
OnCore AVANT 55	Surlyn blend	55	2	Under 90 mph, soft feel, straight flight	$20

Only the ELIXR is fitted in BallCaddie’s ball catalog, so its ~84 compression and $30 MSRP come from our own data. The other four numbers come from OnCore’s product pages, and we haven’t found a recent independent gauge reading for any of them.

What OnCore is actually selling

Every OnCore ball is built on one idea about where the weight should sit. Move mass out of the center and toward the cover, the theory goes, and you raise the ball’s moment of inertia, which slows the rate at which it spins down off the driver and stabilizes flight.

OnCore pushed that idea all the way to a metal core. In 2013 the USGA advised that a rigid core no larger than 0.9 inch could be permitted, and OnCore’s EVO prototype went onto the conforming list that November — the ruling was reported at the time as the approval of a hollow-metal-core golf ball. The MA 1.0 shipped in January 2014 with a hollow steel sphere roughly 0.9 inch across at its center, which Golf Digest covered as the hard-core ball that had just been declared legal. The Caliber followed in 2016.

Both are gone. What survived is the objective, executed through the mantle: the VERO X1 and X2 wrap a conventional core in a metal-infused mantle layer, and the newer VERO XP1 uses a metal-injection-molded mantle that OnCore says raises MOI by 25 percent. The ELIXR does it with a perimeter-weighted polymer mantle and no metal at all.

The metal-core lineage ran MA 1.0 into Caliber, and neither is in OnCore’s lineup today. The AVANT, which old coverage sometimes lumps in with them, launched in 2016 as a conventional soft-core ball.

How to pick an OnCore ball by swing speed

Swing speed is a useful first filter because it shapes how much launch and spin you need. (It doesn’t set a minimum compression: in MyGolfSpy’s 2026 robot test, firm balls were the fastest off the driver at every speed.) OnCore’s five balls sort cleanly across three bands:

Under 90 mph: the AVANT 55 at 55 compression is a 2-piece Surlyn-blend ball built to compress easily and fly straight. It’s the only non-urethane ball OnCore makes, so it trades greenside bite for $20 pricing and durability.
90–105 mph: the ELIXR (~84) and the VERO X1 (85) sit within a point of each other on paper and $10 apart on price. This is where TrackMan’s amateur data puts the average male driver, near 94 mph, so it’s where most golfers reading this belong.
105+ mph: the VERO X2 (95) is the firmest thing OnCore sells, aimed at fast swings that want a firm tour feel.

The VERO XP1 complicates that a little. It carries the same 85 rating as the X1 with the highest-MOI construction in the line at the highest price. OnCore pitches it as the all-round ball and the unreleased XP2 as the one for faster swings, so treat the 85 as your guide and the MOI claim as the reason for the $5 premium.

Don’t know your number? The swing-speed fitting framework covers how to measure it without a launch monitor, and the golf ball compression chart plots the wider market on one calibrated gauge.

The VERO tour balls

The VERO line is three balls at two compressions, $5 apart. It’s where OnCore competes directly with the Pro V1 shelf, at $13 to $18 less per dozen.

VERO X1: the softer tour ball

The X1 is a 4-piece cast-urethane build at 85 compression. Plugged In Golf’s review recorded just over 1,900 rpm of driver spin for the reviewer at a 1.50 smash factor, with full wedge shots stopping where they landed. A second tester with a 105+ mph swing saw average driver spin, not the low spin OnCore advertises. That’s a useful check on the marketing, since high MOI slows spin decay and doesn’t promise low spin at launch.

Golf Monthly’s review put the feel close to a Pro V1x on long shots, with a slightly tinnier sound, and flagged one limitation — lower-flighted drives sometimes fell out of the sky sooner than comparison balls.

VERO X2: the firm one

The X2 is the same 4-piece architecture with the core firmed to 95. Golf Monthly measured it against a Pro V1x and published the numbers most useful for a fitting decision: 2,243 rpm and 282 yards of carry off the driver for the X2, against 1,986 rpm and 291 yards for the Pro V1x. On wedges the X2 produced 6,895 rpm, about 200 rpm above the previous VERO generation and about 200 rpm below the Pro V1x.

The X2 spun more and carried nine yards shorter than the Titleist Pro V1x (~102) in that test, and landed within about 3 percent of it on wedge spin, for $18 less per dozen. Whether that trade is good depends on whether nine yards of carry or $18 matters more to you.

VERO XP1: the newest and priciest

The XP1 is the 2025–26 release: 3-piece, an NRG core, a dense MIM mantle, and a 0.035-inch cast-urethane cover at $44.99. It’s the only OnCore ball priced within $13 of a Pro V1. We haven’t found an independent review with published launch-monitor numbers for it, so the MOI claim is OnCore’s word for now. A VERO XP2 has been announced but isn’t on sale.

The ELIXR: the OnCore ball we actually fit

The OnCore ELIXR (~84) is the only OnCore in BallCaddie’s fitting catalog, and for most golfers it’s the right one anyway. It’s a 3-piece urethane ball at $30 — roughly half a Pro V1 — built on a polybutadiene core with a perimeter-weighted polymer mantle.

Plugged In Golf’s review of the enhanced generation measured driver spin less than 5 percent below the reviewer’s own tour ball, with half- and full-wedge spin within a few hundred rpm of premium alternatives, and described a premium putter feel with a soft, almost squishy sensation on full wedges. Golf Monthly’s take singled out long-game distance and cover durability, with slightly more rollout than comparison balls on partial wedges.

OnCore’s own product page says the enhanced white ELIXR uses the newer polybutadiene core and a 350-dimple cover at 84 compression, while the yellow and matte green versions keep the original 318-dimple build at 80. The reviews above are of the newer ball.

Our catalog also rates the ELIXR as cold-weather friendly. An 84-compression core holds feel and carry below 60°F better than the 95-compression X2 will, which makes it the OnCore to keep in the bag through shoulder season.

What the quality data actually says

Ball Lab has cut the ELIXR open twice, and neither report is clean. Read both before you order six dozen.

MyGolfSpy’s Ball Lab teardown of the original ELIXR, published in November 2020, flagged 14 percent of the sample as bad for layer concentricity and noted minor defects in another 42 percent. Compression across the sample spanned nearly 14 points, and two different core compositions turned up in the same sample. The True Price came to $42 against a $35 MSRP — 20 percent over retail. Average measured compression was 78.

The second teardown is the one that applies to the ball on sale now. In March 2023 Ball Lab tested the enhanced 350-dimple ELIXR, which it traced to Launch Technologies instead of Foremost (both in Taiwan). Compression averaged 83 with a 7.3-point spread, and every ball conformed for diameter and weight. Five of 36 were still flagged bad: three for thin spots in the mantle, and two with pale cores that weren’t ELIXRs at all, which OnCore put down to a factory mix-up. The score was 75 on Ball Lab’s pre-2026 scale, two points above the database average at the time, with a True Price of $34.84 against $30. In both teardowns every ball passed for roundness and stayed under the USGA’s 1.620-ounce weight limit, so these are consistency findings and the balls still conform.

No OnCore ball has been through Ball Lab’s relaunched 2026 scoring, so that 75 can’t be set beside this year’s numbers. What 2026 does show is what a clean sample looks like: the Wilson Staff Model, which scored 90 out of 100 in 2026 Ball Lab testing with zero bad balls in 36. That’s the reason a $30 ELIXR isn’t automatically a better buy than a Kirkland Signature V3 (~95), which runs about $15 a dozen in the Costco warehouse ($29.99 for two dozen) and about $20 shipped from Costco.com ($39.99 for two dozen). Our fuller read on how much the factory decides is in golf ball brands, ranked.

Buffalo, investors, and the GENiUS ball

OnCore was founded in Buffalo, New York in November 2011 by Bret Blakely and Steve Coulton, and still runs from downtown Buffalo. It sells primarily direct, and skipping conventional pro-shop distribution is what funds the gap against major-brand premium prices.

The investor roster is unusually athletic: Charles Schwab came in during 2018, and the shareholder group has included Josh Allen, Ezekiel Elliott, Gary Player, and Thomas Pieters. One name that circulates doesn’t check out. We found no record of Ernie Els investing in OnCore; his documented golf-tech investment was in 18Birdies.

On the tour side, OnCore was the official ball of the 2023 APGA Tour, put the VERO X1 in PGA Tour veteran Erik Compton’s bag, and the X1 is the official ball of Pro League Network’s Putt Tour series. That’s validation a level below the PGA Tour, and none of it shows up in PGA Tour ball counts.

Then there’s GENiUS. Announced in 2017 as a GPS-equipped ball that would report location, speed, flight, and spin, it became the i-Roll sensor ball for putting and wedge play by 2023 — OnCore’s own explanation being that onboard sensors plus Bluetooth removed the need for GPS, and that a metal shell would have blocked the signal anyway. A putting-only GENIUS ball debuted at the January 2026 PGA Show at $240 for three balls, a case, and a year of the app, with shipments planned for Q2 2026. Nine years on, OnCore’s technology page still lists the tee-to-green version as coming soon, so don’t factor it into a ball purchase.

Is OnCore worth it?

For the 90–105 mph golfer who wants urethane and doesn’t want to pay $57.99, yes — the ELIXR at $30 is the pick, and the numbers behind it are close enough to premium balls that you’re unlikely to see the gap on the course. The VERO X1 at $40 buys a fourth layer and a slightly firmer feel; whether that’s worth $10 comes down to feel.

The mismatches:

You swing under 100 mph and grabbed the VERO X2. Your swing still compresses it, but you’re paying for firmness and spin you may not want. The ELIXR or X1 at 84–85 feels softer.
You’re shopping purely on price. The Kirkland Signature V3, at about $15 to $20 a dozen, is urethane too, and undercuts the ELIXR by $10 to $15. Its build consistency is better documented, though the record is uneven: earlier versions varied badly dozen to dozen, while the 2026 Ball Lab reports scored the yellow V3.0 84 and the white 85, both a grade B, with zero defects across 36 balls each. The best value golf ball guide runs that cross-shop properly.
You need documented lot-to-lot consistency. Ball Lab’s last look at the ELIXR, in 2023, flagged five bad balls in 36. The 2020 VERO X1 did better at 84 on the same pre-2026 scale, but nothing in the line has been through the 2026 retest.
You want the metal-core ball. OnCore no longer sells one; the last, the Caliber, launched in 2016. The current balls put the metal in the mantle.

On conformance: OnCore’s current balls are standard conforming products. Before a competition, check your exact model against the current USGA and R&A conforming list.

The next step

This guide narrows OnCore to the one ball that fits your swing and budget. To pressure-test that against the wider market, take the BallCaddie fitting quiz — it scores the ELIXR alongside the rest of the catalog on swing speed, typical miss, greenside priority, and budget. The quiz runs about 90 seconds. Your fitting report is free; your #1 ball is paid. The ranking carries no affiliate tilt toward the pricier ball.

Key takeaways

Five balls, one thesis: perimeter weighting, now delivered through metal-infused and MIM mantles.
The ELIXR (~84, $30) is the pick for most golfers — roughly half a Pro V1’s price, with Plugged In Golf measuring driver spin under 5 percent below the reviewer’s own tour ball.
The VERO X2 traded nine yards of carry for $18 against a Pro V1x in Golf Monthly’s test, at 2,243 rpm versus 1,986 rpm off the driver.
The quality data is OnCore’s weak spot: Ball Lab flagged 14 percent of the original ELIXR sample in 2020 and five of 36 balls on the current one in 2023.
The metal core is history — MA 1.0 in 2014, Caliber in 2016, both discontinued.
GENiUS is still coming soon for tee-to-green play, nine years after announcement. Buy the ball in front of you.
