Hello! How can we help you?

Which grips should I choose?

Hands come in all different shapes and sizes. You can easily measure your grip size measurement at home. Your Trionic grip size is the measurement in inches or centimetres around the palm of your hand. If you are right-handed, measure your right hand. If you are left-handed, measure your left hand. Use the table to find your best match.

Grip Options

You can choose between two different grips, that are both available in two sizes.




Ergon GP1

The original ergonomic grip. The GP1 sets the Worldwide standard in ergonomic comfort, materials and quality.

The GP1 eliminates numb hands, aching fingers and tyred forearms.

The uniquely shaped grip body is made from 100% German, TÜV-certified rubber compounds of the purest quality – with infused Medical-grade white mineral oil for improved flexibility and durability. A forged aluminium clamp allows the grip angle to be adjusted for a perfect fit, can be easily readjusted and eliminates twisting once installed.


Size: S (hand size 6.5–8.5) or Size: L (hand size 8.5–12.0)

Ergon GP1 BioKork

Combining ergonomics, function and sustainability, the GP1 BioKork is a top-rated grip and a consumer favourite.

The grip is made from 40% cork, sourced from sustainable forests in Portugal, which are certified for their ecologically sound production. This green, sustainable theme is echoed throughout the complete construction of the grip, with an inner core made of a reinforced plastic containing natural fibres, which make up 20% of its mass.


Size: S (hand size 6.5–8.5) or Size: L (hand size 8.5–12.0)




"Numb fingers, painful hands, or forearm discomfort—common problems that many rollator users experience. Ergon grips solve these issues and correct the root of the problems."
