Product Overview

A soft foam grip provides a compressible hand contact around a bicycle handlebar. The NBR foam sleeve needs an internal fit and an installation method suited to the supporting bar, particularly where it must pass an end feature before reaching its final position. Pulling hard on one thin edge can damage the foam before the grip is fully installed.

Check the usable bar length and clearance beside the controls. The grip should reach its intended position without bunching or pushing against a lever assembly. Any installation aid needs to suit the materials and leave the finished sleeve securely retained once assembly is complete.

Before riding, check that the grip cannot rotate or slide unexpectedly during normal hand movements and that nearby controls remain unobstructed. A soft feel does not establish secure attachment. Inspect the ends and main hand contact for tears or lasting compression during routine care, and keep residues from changing the surface feel. If the sleeve becomes loose, address its retention before use rather than relying on a tighter hand hold to keep it positioned.

Material options
NBR foam for the handle cover; density and cellular structure selected around the required grip feel.
Hardness range
For bicycle grips, consider 35-45 Shore C to balance a cushioned feel with support at the handlebar. Hardness can be tailored to your preferred riding feel.
Custom shape & size
Bore, outside profile, wall thickness and grip length matched to the handlebar and intended hand position.
Color & OEM
Custom colors and OEM packaging; marking options reviewed for the foam surface.
Tooling & samples
Samples evaluated for cushioning, handle fit and resistance to unwanted rotation.

The photos illustrate a foam grip's structure and material, rather than a fixed size or hand feel. ETOL manufactures custom-shaped silicone and rubber products directly, tailoring this cover's bore, wall and length to your handlebar and grip requirements.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
