Just got these grips on a new bike and would like to replace them but keep the clamp they came with.

Not ODI style but someone might have seen something similar from Race Face etc.

Single (inner) clamp.
Clamp area is 10.8mm
One cutaway area to match flat on clamp.

Cheers

That looks like a superstar grip

does to me too. My old Spearfish came with Superstar Grips like them.

Aye, could well be a generic brand/design that SS have picked up.

Any other ideas of brands that might use this type of clamping folks?

Discobrakes/Carboncycles and many eBay sellers unbranded jobs.

All the Superstar grips appear to have two grip areas with two flats.

Same with Carboncycles/Discobrakes (apart from one Waffle grip)

It’s cool, I found them. It’s the same clamp as the Raceface Half Nelson.
