It still maintains high speed and excellent maneuverability, but with a slightly \"fuller\" feel underfoot.\u003c\/p\u003e\n\u003ch3\u003eWhat skill level is recommended for this kit?\u003c\/h3\u003e\n\u003cp\u003eThe kit is suitable for intermediate-advanced riders who already have good control of wing foiling. It can also be a top choice as a first high-performance setup for those coming from larger, slower freeride foils.\u003c\/p\u003e\n\u003ch3\u003eIs it suitable for wave use or more for freeride?\u003c\/h3\u003e\n\u003cp\u003eThe Balz Pro 905 is a true all-around wave\/freestyle\/fast freeride, with great fluidity in turns and hold in steep sections. It also performs very well for fast freeride, especially if you enjoy surfing chop and varying wave sizes.\u003c\/p\u003e\n\u003ch3\u003eCan I customize the foil's behavior?\u003c\/h3\u003e\n\u003cp\u003eYes, thanks to the modular full carbon fuselage, you can try different stabilizers and use positive or negative shims to modify lift, speed, and feel. This way, you can make the kit more stable and \"locked-in\" or more free and flowing, depending on your style.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference compared to the 965 Balz Pro?\u003c\/h3\u003e\n\u003cp\u003eThe 965 offers even more lift and support at low speeds, making it easier for starting and pumping, but less twitchy and quick in direction changes than the 905. The 905 is the ideal compromise for those who want comprehensive performance across speed, maneuvers, and wave control.\u003c\/p\u003e\n\u003ch3\u003eIs the 85 cm mast sufficient for chop and waves?\u003c\/h3\u003e\n\u003cp\u003eThe 85 cm height is an excellent compromise for handling chop, waves, and touchdowns, with enough clearance for deep carving without breaching the water. It also provides enough leverage for significant jumps and aggressive freestyle maneuvers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e```\u003c\/p\u003e","brand":"Sabfoil","offers":[{"title":"998 \/ 370 \/ To modularize","offer_id":61467933966666,"sku":"KBZ905-FCM-370-85\/BB","price":1889.0,"currency_code":"EUR","in_stock":true},{"title":"998 \/ 385 \/ Integrated","offer_id":61467933999434,"sku":"KBZ-905-385-85\/BB","price":1889.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/3547\/6810\/files\/Screenshot2026-03-31alle15.11.13.jpg?v=1774962879","url":"https:\/\/shop.zzsurf.com\/en\/products\/bb-balzpro-905","provider":"ZZSURF","version":"1.0","type":"link"}
