Swix Top Speed Black (TSB) waxes are gliders for competition that work exceptionally well on warm wet dirty snow as well as cold dry friction conditions. The TSB line has excellent durability thanks to a solid black lubricant that reduces friction. TSB can be used as a race wax alone but is often used as a base for top coats. Replaces HFBWX (Black Wolf) race wax. This wax line is part of Swix’s fluoro-free racing glide wax system and is based on new speed additives that conform to their global sustainability strategy. Environmentally friendly and fit for racing and performance-oriented training. They follow the traditional color and number logic for wax selection. TS10B 180g Yellow 0°C to +10°C (32°F to 50°F): TS10B is an excellent wax in wet conditions, typically when new or transformed snow is melting. Repels dirt reducing friction in contaminated snow. Recommended iron temperature setting of 120C (248F).
