Excellent price on a quality aero helmet with some venting. Limited quantities available.
The Rudy Project Synton Open helmet is a budget-conscientious Tri-TT helmet designed to improve performance and keep you cool. Rudy targeted their research effort for total air flow control. The design team at Rudy Project consider the Synton a technical breakthrough because it delivers the quite significant benefit of outstanding aerodynamics with quality venting. So now you can get the benefit of an aero helmet for hotter and longer events without the worry of excessive heat buildup.
Venting is accomplished with two front ports plus an internal air channel system that exhausts air through six rear ports, two side ports and three top ports. The vent holes are designed specifically to balance aerodynamic efficiency with heat escape and air movement. This allows better temperature control compared to less vented aero helmets. Other details include a RSR Micro T retention system for easy adjustment and an optional Visor lens available separately - not included. S-M size fits a 54-58cm (21.25-22.75") diameter noggin.
