Sub 70 sells the 639 CB for about a hundred bucks per iron, direct from their shop in Sycamore, Illinois. That number tends to dominate any conversation about this club, which is a shame, because the iron underneath the price tag holds up on its own. This is a forged players cavity back with a compact head, a thin topline, and minimal offset. Set it down next to irons costing twice as much and nothing about it looks budget.
The pitch is simple. Sub 70 skips the retail markup and the tour advertising budget, forges the head from soft carbon steel, and lets you build the set with a long list of shafts at little or no upcharge. Founder Jason Hiland spent years running a component club business before launching the brand, so the direct model isn't a gimmick bolted onto a startup. It's the whole company.
What you give up is the fitting cart experience at a big box store and the resale recognition of a Titleist or Mizuno stamp. What you get is a legitimate players iron, built to your specs, for the price of a mid-tier set. For a lot of single digit handicaps, that trade is easy.

About the Sub 70 639 CB
The 639 CB is forged from 1025 carbon steel, and it feels like it. Strikes off the center are soft and quiet, and misses tell you exactly where you caught them. The cavity is shallow and honest. There's enough perimeter weighting to take the sting out of a slightly thin strike, but this is not a game improvement iron wearing a players costume. The head is compact, the sole is reasonably narrow, and the ball flight is controllable rather than launched. Sub 70 offers the head in a brushed satin or a black finish, and the black version has a clean, understated look that photographs well and wears about how you'd expect a dark finish to wear. Shaping stays consistent through the set, so the transition from long iron to wedge doesn't produce any visual surprises at address.
Who Should Play the Sub 70 639 CB?
- ✓Low to mid single digit handicaps who want forged feel and workability without paying $1,400 for a set.
- ✓Players considering a 639 MB blade who would honestly benefit from a little cavity back help on mishits.
- ✓Combo set builders, since Sub 70 will happily mix the 639 CB with their more forgiving 699 heads in the long irons.
- ✓Golfers who know their specs, or don't mind a phone fitting, and don't need to hit the club in a store before buying.
자주 묻는 질문
Is the Sub 70 639 CB forgiving enough for a mid handicapper?
It depends on your ball striking more than your handicap. The cavity gives you some help on small misses, but the head is compact and the sole is narrow, so fat strikes and big toe misses will cost you distance. A 12 handicap who hits the center often can play it. A 12 handicap who struggles with contact would be happier in the 699 or 699 Pro.
How does the 639 CB compare to the 639 MB?
Same family, same forging, different margin for error. The MB is a true blade with a smaller sweet spot and slightly better workability. The CB adds perimeter weighting that keeps mishits closer to your normal distance. Plenty of Sub 70 buyers split the difference and run MBs in the short irons with CBs up top.
Why is the Sub 70 639 CB so much cheaper than a Mizuno or Titleist?
Direct to consumer economics. Sub 70 doesn't pay retail margins, doesn't run tour player contracts, and doesn't spend heavily on advertising. The forging and materials are comparable to the big names. You're paying for the club, not the marketing around it.
Can you get the 639 CB custom fit?
Yes, and you should. Sub 70 offers phone and email fitting consults, a demo program so you can try a head before committing, and a wide shaft and grip catalog with most options at no upcharge. Lie angle, length, and grip adjustments are all part of the order process.
What handicap range is the 639 CB designed for?
Sub 70 positions it for roughly scratch to low double digits, and that matches how it plays. It rewards consistent contact and gives you real feedback on misses. If you're above a 15 or still developing your strike, the extra help in Sub 70's 699 line will save you more shots.
