About the Tour Edge Hot Launch C522

The Hot Launch C522 is the second Competition Spec iron in Tour Edge's value line, announced in autumn 2021 and at retail from November 2021 as the 2022-season line. It strengthens the C-range ladder by two to three degrees over the C521 — a 29-degree 7-iron and 43-degree pitching wedge that would carry through the C523 and C524 unchanged — and introduces VIBRCOR, a feel-enhancing TPU fill inside an expanded 360-degree undercut cavity, to the Hot Launch line. The wide-sole, toe-weighted 431 stainless head carries over, the stock graphite shaft moved to Mitsubishi Chemical's 50-60 gram Fubuki HL, and the KBS Max 80 remained the steel option. Sold right-handed with matching C522 hybrids for combo sets.

Frequently asked questions

What is the loft of a Tour Edge Hot Launch C522 7-iron?

The Hot Launch C522 7-iron has a loft of 29 degrees, a lie of 62.5 degrees and a length of 37.25 inches.

How do the C522 lofts compare with the C521?

The C522 strengthened the whole ladder — the 7-iron went from 31 to 29 degrees and the pitching wedge from 44 to 43 — and that stronger ladder then carried through the C523 and C524 unchanged.

What is VIBRCOR in the Hot Launch C522?

VIBRCOR is a high-grade TPU material injected into the deep undercut cavity. It damps sound and vibration for better feel while contributing to the perimeter weighting, and the C522 was the first Hot Launch iron to use it.

What shafts did the Hot Launch C522 irons come with?

The stock graphite shaft was Mitsubishi Chemical's super-light Fubuki HL at 50 to 60 grams depending on flex, with the KBS Max 80 as the stock steel option.

Finding a used set

The Tour Edge Hot Launch C522 ran from 2021 to 2022 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.

Year note: the Hot Launch 522 series was announced in autumn 2021 with retail from November 2021, marketed as the 2022 line; year_introduced records the announcement year per the schema convention. Tour Edge does not publish offset, bounce or swing weight for this model, so those keys are omitted.
