[New Onza Ibex](https://www.onza-tires.com/products/ibex)
Not quite into 750g unicorn territory, but the **Onza Ibex** in soft compound comes pretty close in a recent Bike (Germany) Magazine tire test.
They rated it equal to a Butcher T9 in cornering and braking traction (which itself was near the top of the Trail bike tires for grip). But, weight for the 2.4 Ibex was 852g vs 982g for the Butcher(grid casing).
And even more impressively, in the drum rolling resistance test it had **_19W_** of rolling resistance vs 42W for the Butcher! (And most other grippy tires were similar to that)
For comparison, that is similar to what they measured for a Nobby Nic in Speedgrip compound, and identical to a **Recon Race** in **Dual compound**!
The ‘_no free lunch_’ comes in the form of reduced pinch- and puncture-protection.
So, either add an insert, or run it front only, but it is certainly an interesting option for this sort of bike, especially if your trails have deep, loose dust or wet.
