Hello all,

I am selling authentic, brand new, unused and undamaged Yonex Poly Tour Pro 17 reels (1.20mm thickness) also known as Yonex PTP 120 or PTGP120. 17 gauge

Each reel has the full 200m / 656 feet length of string and is still in the unopened packaging from Yonex

The reels are made in Japan🇯🇵 and the strings are Cobalt Blue

• Co-polyester monofilament tennis string with a round profile designed for modern, controlled ball striking. Gauge: 17 (1.20 mm) in Blue. Single-set length: 39 ft / 12 m. Made in Japan. Product code often listed as PTPRO12012B.  

• Why players choose it

• Known for a softer, more arm-friendly feel for a poly while preserving the directional control people expect from polyester. Frequently described as spin-friendly with a plush “pocketing” response on full cuts. 

• Play characteristics (lab-style signals)

• Spin Potential (TWU index): ~5.2 for the 1.20 mm version (unitless ratio; higher = more snapback/spin headroom in their rig).

• String-to-string friction (COF): ~0.093 measured in Tennis Warehouse University testing (lower COF supports easier snapback). 

• Fit & use cases

• 17 g/1.20 mm suits hitters who want a livelier response and easier spin access than thicker gauges while keeping a predictable launch angle. Retailer notes explicitly call out the thinner gauge’s added spin potential. 

• Typical stringing approach

• Install at or slightly below your racquet’s recommended mid-range; a common baseline for polys is stringing a bit looser than nylon/gut (e.g., ~2 lbs below the middle of your frame’s range). This keeps the response lively without sacrificing control.  

• Packaging options

• Single set: 12 m (39 ft) in Blue.

• Reel: 200 m (≈660 ft) for frequent restringers or multiple frames. Blue reels in the 1.20 mm gauge are widely available.  

• Series context

• Part of the Yonex POLYTOUR PRO family, produced in multiple gauges (1.15/1.20/1.25/1.30 mm) across the line; the Blue 17 g variant highlighted here is the 1.20 mm option. 

• Pro tour visibility (as listed by retailers)

• Retailer pages associate the POLYTOUR PRO line with players such as Elise Mertens (Blue 17 page) and, for the 1.20 mm line in other colors, Nick Kyrgios and Jasmine Paolini. 

• Construction highlights

• Polyester (monofilament) build for a clean, consistent response; many listings note controlled-temperature stretching in manufacturing to bolster consistency and durability.  

• Type: Co-poly monofilament (round)

• Gauge: 17 / 1.20 mm

• Color: Blue

• Length: 200 m reel (≈660 ft)

• Origin: Japan
