Vision TriMax UCI Alloy Base Bar

This flat (0mm drop) wing-shaped base bar is made from high-strength triple-butted 6066-T6 aluminium, allowing a complex aero shape at low weight. A broad, straight 31.8mm centre section gives plenty of room for stem and clip-on aero extensions. The bar flattens into aerodynamic wing sections before curving into a powerful forward section. Full internal cable routing ensures that disrupted airflow is kept to a minimum.

UCI (Union Cyclist Internationale, cycle sport's world governing body) regulations demand that base bar profiles conform to a 3:1 depth to height ratio. In other words, the tube diameter measured front to rear can't be more than three times the diameter measured top to bottom in a UCI-sanctioned event. Make sense? Vision, a sub-brand of FSA, has redesigned these base bars to fall into line with this rule.

Since its birth in Kona in the '90s, Vision has been synonymous with a no-expense spared assault on wind resistance.

Recent years have seen the innovative application of carbon fibre and the creation of dream-like shapes to enhance performance.

Vision is the brand to beat, leading the way in time trials and triathlon by creating slippery-fast aero products with proper fit adjustment that allow the rider to push their limits in race conditions. Vision continually refine, test and innovate in the quest for speed, with industry-leading products throughout the range.
