Buying Guide
Aerodynamics and Positioning
In time trials, small posture changes can yield meaningful drag reductions. Aero handlebars like the Legacy II add forward reach and arm support to maintain a low, stable torso angle. When choosing components, consider how easy it is to adjust width, rotation, and fore-aft position. A noseless saddle can help maintain a hydrodynamic line while safeguarding leg clearance, but ensure you can ride it comfortably on long efforts. For helmets, look for streamlined shells with proper venting to minimize drag while keeping you cool in hot conditions.
Helmet Selection for TT and Triathlon
Helmet choice directly affects aerodynamics and safety. TT-specific helmets with visors or integrated goggles help reduce wind resistance and protect eyes at high speeds. Magnetic visors allow quick lens changes without removing the helmet, while vent layout matters for cooling. For events with rapid transitions, a helmet that balances a tight fit, light weight, and easy visibility is ideal. Safety certifications such as MIPS and robust impact protection should guide selection, especially on challenging TT courses.
Tire and Wheel Setup
Tire selection influences rolling resistance, weight, and grip. Time-trial tires like the MICHELIN Power TT line are designed for efficiency, with compounds and tpi counts that reduce drag while maintaining durability. Ensure your rims and brakes are compatible with the chosen tire width. The correct tire pressure is essential for minimizing contact patch and rolling resistance, but must be tuned to ride conditions and personal preference. Consider tubeless options or sealant if you frequently encounter nails or debris on race day.
Saddle and Comfort
A noseless saddle can improve blood flow and reduce numbness on long TT rides, but comfort remains rider-specific. The ISM PN 3.1 emphasizes leg clearance and a forward-facing cushion to support continuous pedaling. When selecting a saddle, assess sit bone width, riding position, and the need for frequent sprints or aggressive corners. A well-chosen saddle reduces pain points and helps you maintain power without distraction during critical race segments.
Budget, Durability, and Maintenance
Durability and maintenance are practical considerations beyond initial performance gains. Aluminum components often balance cost and strength, while high-end helmets emphasize protection features beyond basic safety standards. Regular inspections of aero bars, levers, and quick-release mechanisms prevent performance issues during races. Keep all fasteners tight, clean, and free of corrosion, and replace worn parts promptly to preserve consistent handling and braking performance across training and race days.
