LeMieux Vector Contol Stirrup The LeMieux Vector stirrups are a new generation of safety stirrup - technically advanced and lightweight, but retaining a classic style expected from LeMieux Machined from aviation grade aluminium offers an impressive strength to weight ration, making them lighter than most stirrups on the market at just 419g each, whilst not compromising on stability. The ergonomic footplate of the Control Stirrup is set at 0º with a cross-track grip surface with embedded hardened steel pins to provide maximum security of the boot. The footplate is supported by a twin balance arch system that distributes the weight evenly across the base of the stirrup frame. The apex of the frame is recessed and off-set, encouraging a 45º outward orientation which makes it easier for the rider to locate the optimum angle for the foot and regain a lost stirrup.
