The GA3 with Miniwing support is based on the well-established and proven design of the MTB-specific GA2 grips. The particular shape of the grips provides you with great comfort and grip, without compromising the freedom of movement. This allows you to have all the control you need to tackle the most demanding of trails with full confidence.​​ Ergon partners with Supernova to create an ergonomic and sleek design to control your bike light. The design allows you to keep your hands on the handlebars and easily switch your bike lights on and off whenever needed. The switch for your lights is constructed within the Ergon grip clamp and can be used with Supernova M99 and MINI 2 PRO series lights. This control is perfectly integrated within the clamp of the Ergon GA3 grip.​​ Combining trail-proven ergonomic shaping with a secure lock-on clamp and integrated light control, these grips are engineered for riders who demand comfort, precise handling, and convenient on-bar lighting operation. The lock-on system ensures reliable attachment while the Miniwing profile supports wrist ergonomics for longer rides and technical sections. Ideal for mountain biking and all-terrain use, these ergonomic grips deliver improved control, reduced fatigue, and seamless access to Supernova light switching without removing your hands from the bars.
