Push rims: “Curve” and “Curve Large” by Carbolife


No more bumps, all the suspension is in the wheels itself, even going up and down curbs.

The biggest thing I have noticed is no more pressure on my back/spine.

CURVE handrims – perfect ergonomics with each propulsion.
Based on the natural anatomy of the hand, the Curve’s ergonomically optimized profile guarantees a controlled and effortless grip, while stabilizing the wrist.
Full control with Curve – the ergonomic push rim for active wheelchair users. Engineered and made in Germany by CarboLife.


Who are Curve push rims suitable for?

For wheelchair users with complete hand function.

What are the advantages of the CURVE handrims?

The innovative profile enables you to gain controlled, low-effort grip while stabilising your wrist. Compared to conventional handrims, the hand muscles tire less and so help to reduce cramps and relieve pain due to carpal tunnel syndrome creating a relaxed and lasting riding experience.

What is the manufacturer’s recommendation in terms of profile size and coating?

Wheelchair users with small hands should use the small CURVE profile. If you have normal-sized or large hands, we recommend choosing the larger CURVE L profile. Those who enjoy fast downhill rides in higher temperatures should use the anodised surface.

Two push rim sizes are available:

Weighing just 470g, Curve Large is a very lightweight, ergonomic hand rim. Available in anodized aluminum, with a black, matt finish. With its height of profile of 31 mm, Curve L is especially made for average and large hands.

Weighing just 330g, Curve may be the world’s lightest ergonomic hand rim. Available in anodized aluminium, with a black, matt finish. With its height of profile of 24 mm, Curve is especially made for smaller hands.
