- Veloflex Corsa Evo TLR 25
(100% is best)
Veloflex is a small tire company that designs and manufactures handmade cotton tires in Italy. Veloflex revamped many of their tires in 2020 and released their first tubeless-ready road bike tires with the Corsa Race TLR and Corsa Evo TLR. The Corsa Race is the fastest, with the Evo version being oriented a bit more towards durability.
The main difference between the Corsa Race TLR (read our review) and Corsa Evo TLR seems to be the casing which is 350 TPI corespun on the Corsa Race TLR and 320 TPI corespun on the Corsa Evo. The 320 TPI casing is slightly thicker and should make the Evo TLR a bit more durable and puncture-resistant when compared to the thinner and lighter 350 TPI casing.
When we look at all the other specifications, there don't appear to be many other differences. The specified weight of the Evo TLR is just 10 grams higher than the Race TLR, which is an indication that the casing is the only thing that's changed. Both tires come with the same Air-Lock membrane and non-extendable Zylon beads that make it tubeless-ready. The tread is also the same as both tires use the "natural rubber and silica exclusive" compound and the same RKB (Resilient Kinetic Belt) to add extra puncture protection
Mounting the Corsa Evo TLR was very similar to the Corsa Race TLR, as it was effortless to get onto the rim but required an air compressor to get the tire inflated (may be different on other rims). Sealing also wasn't that spectacular as this tire requires a couple of hours for the sealant to do its job; you can't just mount these and go for a ride as you won't get far.
Unlike the Race TLR that's only available in the 25-622 size, you can get the Evo TLR in both the 25-622 and 28-622 sizes. If you like cotton tires with gum/tan sidewalls, the Evo TLR and Race TLR are pretty much the only option for tubeless tires.

| 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
- Veloflex Corsa Evo TLR 25
(100% is best)
Performance of the Veloflex Corsa Evo TLR comes very close to the Veloflex Corsa Race TLR (read our review) with the Evo TLR having a slight edge in puncture resistance at the cost of a 12% higher rolling resistance.
We're not sure if the durability of the tread will be higher than on the Race TLR as there hardly is a difference when we look at the total tire thickness at the center of the tread and consider that some of that 0.2 mm is consumed by the slightly thicker casing. The weight is still exceptionally low for a tubeless-ready road bike tire that offers good puncture resistance.
If you have to choose between the Evo TLR and Race TLR, it's going to be up to you to decide which will suit you best. In that case, we recommend you to jump over to our comparison section and compare them side by side: Veloflex Corsa Evo TLR Vs Veloflex Corsa Race TLR.
