Several months ago, Proto Concept announced the C03 TC cavity-back iron which replaced the original C03 CB model that it launched a bit over a year ago. As one might expect, the JDM (Japanese domestic market) upstart is also replacing the first-generation C01 muscle-back iron with the C01 TB. Technically, the moniker is C01 TBic—we’ll handle that “ic” part momentarily.
If you know me, you’re aware that I have a fever for Japanese gear and the only cure is more Endo-forged irons and wedges (though I wouldn’t balk at a forged cow bell, I suppose). That aside, the objective of the C01 TBic is to provide golfers with a true muscle-back iron that can be paired with the C03 TC, though the C01 TBic is offered from 5-iron through pitching wedge for those who wish to play a full set of blade-style irons.
It’s also fair to note that the C01 TBic is the embodiment of a niche product. It caters to highly skilled ball-strikers who aren’t easily dissuaded by an elevated price tag, like $450 per club elevated. That said, the standard pricing disclaimer applies: If expensive goods draw your ire, you’re likely not the target consumer. Moreover, the existence of luxury items does not eliminate the availability of lower-priced alternatives.
Proto Concept Refresher
Plenty of golfers know the name Lydia Ko. Serious followers might recognize Haeji Kang or Ryuji Imada. What they have in common is that they’re part of a growing contingent of professionals playing Proto Concept equipment.
With that, Proto Concept isn’t as recognized as JDM stalwarts Miura, Epon or Yonex. Growing a brand takes time, particularly when you won’t find it in your local big box retail store. So there’s that.
