- Pirelli P Zero Velo Race TLR SL 26
(100% is best)
The Pirelli P Zero Race TLR SL is a faster and lighter version of the Pirelli P Zero Velo Race TLR (read our review). To make it faster and lighter, Pirelli simply removed the puncture strip under the tread and also made the tread a little thinner.

All other aspects of these tires are essentially the same as both the Race TLR and Race TLR SL come with a tubeless-ready 120 TPI casing and the same SmartEVO compound. The SmartEVO compound is still a balanced compound and not solely optimized to provide the lowest possible rolling resistance.
The Race TLR SL is available in the 24-622, 26-622, and 28-622 sizes. The Race TLR is also available in the 30-622 size but we think it's a good choice to drop that size for the SL as this tire is more targeted towards the performance crowd.

| The Road Bike section is a multi tire size section, air pressures have been adjusted to the measured casing width. All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs. Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load. |

Conclusion
- Pirelli P Zero Velo Race TLR SL 26
(100% is best)
The Pirelli P Zero Velo Race TLR SL offers a low rolling resistance but it comes at the cost of a greatly decreased puncture resistance of the tread. When we compare it to the regular Race TLR (read our review) that comes with a puncture strip and a 25% thicker tread, rolling resistance isn't all that much lower while puncture resistance of the tread drops from 12 points to 8 points for the SL.
We think you'll have a hard time justifying the use of the SL over the regular Race TLR as the performance of these tires is this close. This is a good tire, but we rate the SL a bit lower at 4.0 out of 5 as we think the regular Race TLR is a more balanced tire. Compare the Race TLR SL against the Race TLR side by side.
