Babolat RPM Blast Tennis String Reel 17 (1.25mm) 660 ft Black — Octagonal Spin & Control

Babolat RPM Blast 17 (1.25mm) is a 660-foot reel of octagonal-profile monofilament tennis string designed to deliver exceptional spin, feel, and durability for aggressive baseliners and stringers.

This 660-foot reel in black gives club stringers and frequent players a high-volume supply of Babolat’s spin-oriented polyester. The extruded monofilament features an octagonal cross-section that bites into the ball for increased rotation while maintaining consistent tension and reliable durability. Use it to string multiple rackets, stock a pro-shop, or replace worn mains and crosses without switching brands.

What performance can I expect from RPM Blast 17 on court?

RPM Blast 17 prioritizes spin and control. The octagonal profile creates more friction against the ball, increasing bite and spin potential without sacrificing predictable feedback. Players who hit with heavy topspin will notice improved ball rotation and clearer response on aggressive strokes.

• Spin-focused octagonal shape for enhanced ball bite
• Monofilament polyester composition for controlled feel
• 1.25 mm (17 gauge) balance of playability and durability
• Black color for a clean, professional look on any frame

How does the 660 ft reel suit stringers and frequent string-changers?

A full reel supplies enough string for several rackets, making it cost-effective for stringing shops, clubs, and avid players. Reels reduce the need to repeatedly open packages and ensure consistent string batches. The length also simplifies stocking and inventory for pro shops or tournament stringing stations.

• 660 ft reel covers multiple rackets for ongoing use
• Ideal for club shops, coaches, or players restringing often
• Bulk format reduces packaging waste and per-racket cost

What tension and string patterns work best with this 17-gauge polyester?

RPM Blast 17 performs well at moderate-to-high tensions where control and spin are desired. Lower tensions will boost comfort and dwell time, while higher tensions sharpen control and spin consistency—ideal for players who spin aggressively. Use common patterns (16x19 or 18x20) depending on power versus control preferences.

• Try 50–60 lbs for a starting tension range; adjust to taste
• 16x19 opens produce more bite and spin; 18x20 increases control
• Consider hybrid setups with a softer multifilament for added comfort

How durable and easy to string is this monofilament reel?

As a polyester monofilament, RPM Blast balances long-term tension retention with solid resistance to notching and breakage from heavy hitting. The extruded shape can be a little stiffer than multifilaments, so stringers should ensure clean clamps and smooth feeding to avoid kinks. For players who cut strings often, the reel format reduces waste and simplifies restringing workflow.

• Polyester construction provides strong abrasion resistance
• Octagonal profile may need careful handling while stringing
• Reel format minimizes joins and leftover small-package scrap

Who is this for: Babolat RPM Blast 17 (1.25 mm) reel is aimed at competitive club players, coaches, shop stringers, and tournament teams who want a consistent, spin-oriented polyester available in bulk. If you prioritize increased ball bite, repeatable performance, and the economy of a 660-foot spool—especially for multiple rackets or a busy shop—this reel is a practical, high-performance choice.
