About the Miura CB-57
The CB-57 was the cavity back of Miura's Series 1957 class — the "57" denoting the company's 1957 founding — released in late 2014 as the maker's first new iron after the MB-001 blade of the previous October. A medium-sized players cavity with a narrow top line, it carried a weight bar in the cavity that changes size club to club to tune the centre of gravity through the set, plus the leading-edge sole grind of the MB-001. Lofts were among the weakest in the Miura range, with a 34-degree 7-iron and 47-degree pitching wedge across a 3-PW right-hand-only run. The model was still in Miura's official line in 2017 but was gone from the lineup by the company's mid-2019 relaunch, with no direct successor named. Miura sold heads through dealers and published no standard assembly lengths, so the length column is omitted here.

Frequently asked questions
What is the loft of a Miura CB-57 7-iron?
The Miura CB-57 7-iron has a loft of 34 degrees and a lie of 61 degrees. No standard length was published because Miura dealers built every set to order.
What does the 57 in Miura CB-57 stand for?
It references 1957, the year Katsuhiro Miura's company was founded. The Series 1957 designation is reserved for the designs the Miura family regards as its benchmarks.
Is the Miura CB-57 forgiving?
It is a medium-sized players cavity back — more forgiving than the MB-001 blade thanks to a progressive weight bar that repositions mass by loft, but far smaller than a modern game-improvement iron.
Is the Miura CB-57 discontinued?
Yes. It was still in Miura's line in 2017 but was gone by the company's 2019 relaunch, and no direct successor was named.
Finding a used set
The Miura CB-57 ran from 2014 to 2019 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.

- Note: year_discontinued 2019 reflects the model's absence from the iron lineup on miuragolf.com's relaunched site (archive.org capture of 19 July 2019, which lists CB-301, CB-801, IC-601, ICL and MC-501 only); no direct successor was named, so the successor field is null. Length, offset and bounce are omitted: Miura sold the CB-57 component-style through dealers and no standard length chart was published. Confidence is medium because the numbers come from agreeing secondary charts rather than a surviving manufacturer spec sheet.
