Callaway Quantum Max Over Sized Single Irons
Choose the Callaway Quantum Max OS Single Iron to add a specific club to your set or replace an iron while keeping a forgiving, oversized profile through the bag. The Quantum Max OS is designed for golfers who value confidence at address, useful ball speed and more help on off-centre strikes. Its larger shape gives a reassuring look behind the ball and supports consistent carry across a range of lies.
This retailer-listed steel version is right-handed and comes with a True Temper Elevate 85 steel shaft in regular flex, paired with a 50g Lamkin Crossline 360 Black Cap grip. The single-iron format lets you select the club loft you need rather than buying a complete set. Available head options include 4- to 9-iron, pitching wedge, approach wedge, gap wedge and sand wedge; confirm current loft and shaft availability with the retailer before checkout.
Callaway’s standard Quantum Max OS loft progression runs from 19° in the 4-iron through 55° in the sand wedge. Higher-loft custom specifications are also listed by Callaway for this model, so use the retailer’s selected options to confirm the exact build.

The Bold Golfer FAQs
Got questions? We’ve got answers! If you do not find your answer here, please use the contact page to let us know.
What makes The Bold Golfer different from a traditional online pro shop?
Unlike standard retail outlets, we do not stock physical inventory, manage transactions, or ship orders. We operate as an independent golf publication and globally aggregated product catalog, sourcing real-time deals from trusted manufacturers and merchants worldwide to simplify your golfing gear research.
How do your country-specific live pricing buttons work?
We partner with premium golf merchants across different continents. When browsing a product, simply click the button matching your region (e.g., USA, UK, AUS, or EU) to be directed instantly to an authorised local retailer with current stock and localised pricing.
Do I pay any extra fees or hidden premiums by using your outbound links?
No. Every outbound link on our site redirects you directly to the official merchant's checkout at zero extra cost to you. Our platform is fully supported through tracking commissions paid to us by our retail partners when you complete a qualifying purchase.
Who should I contact if I have an issue with an order or a delivery delay?
Because all sales are finalised directly on our partner merchants' secure websites, any questions regarding order processing, shipping, tracking numbers, or returns should be handled directly with the specific retailer you purchased from.
Are the products featured on your site brand new or pre-owned?
Our automated product feeds primarily highlight brand-new, current-generation golf equipment from major manufacturers. However, when we link to specialised premium clearance warehouses, any pre-owned or refurbished status will be clearly indicated on the partner site.
How do you choose which golf brands and products to feature on your website?
We select brands based entirely on manufacturing compliance, tournament-tested reputation, and user feedback. From industry titans like TaylorMade and Callaway to elite direct-to-consumer simulator labels, we aim to cover the full spectrum of high-performance gear.
How often is the product data and retail stock updated?
We utilise dynamic product data feeds that sync regularly with our global affiliate networks to ensure that our configurations, manufacturer names, and global retail channels remain accurate for our community of golfers.
