Push rim: “Curve Tetra-Grip” and “Curve Tetra-Grip Large” by Carbolife

Clear

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

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

The CURVE TETRA GRIP will take your mobility to a new level.

Who are the CURVE TETRA GRIP handrims suited for?

Designed specifically for tetraplegics with triceps function, and suitable for wheelchair users with complete hand function but limited hand strength.

What are the advantages of the CURVE TETRA GRIP handrims?

Being larger than conventional round profiles, this innovative profile provides tetraplegics with triceps function with a gripping surface optimised for exerting considerably more pressure on the handrim. As a result, propelling the wheelchair along a flat road and uphill requires less physical effort while being much gentler on the joints, and ensures better and more secure wheelchair handling. Along with the extremely durable anti-slip coating, the handrims make riding and steering your wheelchair much safer. When braking, the larger gripping surface helps to distribute the pressure much better and thus reduces heat generation.

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

Generally, we recommend using the CURVE L TETRA GRIP handrim to all tetraplegics with triceps function.

The shape of the CURVE push rim is designed to support limited arm and finger function. For the first time, the innovative profile offers greater contact and pressing area on the push rim, due to its bigger size compared with a conventional round hand rim section.

Curve Tetra-Grip and Curve Tetra-Grip Large are optimised for people with tetraplegia, but are also suitable for any wheelchair user who prefers rubberised hand rims. (If you prefer a non-rubberised push rim, choose the Curve product instead).

Two push rim sizes:

Curve Tetra-Grip Large is a very ergonomic hand rim with a rubberised coating.  With its height of profile of 35 mm, Curve Grip L is especially made for average and larger hands.

Curve Tetra-Grip is a smaller version of this ergonomic design with a rubberised coating. With its height of profile of 28 mm, Curve Grip is especially made for smaller hands.

You can also order these rims with loopwheels, in which case, we will dispatch the wheels ready fitted with the push rims. The fitting that is suitable for loopwheels is the 6 rivnut option. Tab fittings are not compatible with Loopwheels.
