About the TaylorMade RSi 1
The RSi 1 was TaylorMade's mainstream game-improvement iron for 2015 and the model that introduced Face Slot Technology, a pair of slots near the heel and toe of the face in the 3- through 8-irons intended to keep ball speed up on off-centre strikes. The 3- through 7-irons also carry the ThruSlot Speed Pocket in the sole, and the head uses a deep undercut cavity with Inverted Cone Technology. Lofts are strong, with a 30.5-degree 7-iron and a 44-degree pitching wedge, and the stock range runs 3-iron through a 60-degree lob wedge. Specs below are the men's standard steel-shaft build with the True Temper Reax 90 shaft.
Stock shafts
- True Temper Reax 90 — steel · 90 g · flexes: R, S
- TaylorMade Reax Graphite 90 — graphite · flexes: L, M, R, S

Frequently asked questions
What is the loft of a TaylorMade RSi 1 7-iron?
The TaylorMade RSi 1 7-iron has a loft of 30.5 degrees, with a 63-degree lie and a 37-inch steel-shaft length.
What is Face Slot Technology on the RSi irons?
Face Slots are two slots cut near the heel and toe of the clubface in the 3- through 8-irons. They let the face flex more uniformly across its width, which protects ball speed on strikes toward the heel and toe. The 3- through 7-irons additionally have the ThruSlot Speed Pocket in the sole for low-face strikes.
What is the difference between the RSi 1 and the RSi 2?
The RSi 1 is the larger game-improvement model with stronger lofts; its 7-iron is 30.5 degrees against 31 degrees for the RSi 2, and its pitching wedge is 44 degrees against 45. The RSi 2 is a more compact multi-material head with a forged face in the short irons and tungsten weighting in the long irons.
Finding a used set
The TaylorMade RSi 1 ran from 2014 to 2016 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
