Its slick surface encourages the mains to slide, capture the ball and snap back, creating added revolutions while maintaining a forgiving response for power players. Supplied in a standard 12.2 m (40 ft) reel, the RPM Blast 17 is a reliable option for frequent stringers who demand spin, control and a familiar polyester resilience.\u003c\/p\u003e\n\n\u003ch3\u003eHow does RPM Blast produce more spin than traditional strings?\u003c\/h3\u003e\n\u003cp\u003eThe string's octagonal profile increases friction against the ball and the slick coating helps mains move and rebound quickly, creating a snapback effect that generates extra rotation.

Babolat RPM Blast 17 is targeted at club players, tournament competitors and heavy topspiners who want a spin-biased polyester that is slightly more forgiving than older, harsher monos. It suits big-armed baseliners seeking enhanced rotation and control, stringers building hybrids to balance comfort and bite, and anyone preferring a 1.25 mm gauge for its versatile play characteristics. If you string frequently and prioritize spin without sacrificing comfort entirely, RPM Blast 17 in black is a strong match.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is RPM Blast 17 good for beginners?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It can suit beginners who want spin, but its polyester feel is firmer than multifilaments; consider a hybrid or lower tension for extra comfort.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use RPM Blast 17 at high tension?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: You can, up to the 66 lb max recommended, but higher tension increases stiffness—lower tensions improve comfort while still offering spin.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Babolat","offers":[{"title":"Default Title","offer_id":48020246626465,"sku":"B0039AH8J4","price":67.7,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0758\/6532\/5729\/files\/babolat-rpm-blast-17-front-packaging.jpg?v=1791293612","url":"https:\/\/canadiansporting.ca\/products\/babolat-rpm-blast-17-gauge-tennis-string-black","provider":"Canadian Sporting","version":"1.0","type":"link"}
