- Challenge Strada Pro HTLR 25
(100% is best)
The Strada Pro is Challenge's all-round road bike tire for a wide range of conditions. We already tested an older clincher version of the Strada Pro back in 2017 (read our review) and found it to be an average performer in our tests. As 2017 is a long time ago, it's interesting to see how the newer tubeless version stacks up to the best tires of the last couple of years.

The Strada Pro is closely related to the Strada Bianca Pro (read our review) that we tested a while back in the 36 mm size. The interesting part is that both the Strada Pro and Strada Bianca Pro are available in the 30 mm size which can be a bit confusing. The main difference is the Strada Pro comes with a finer 300 TPI casing while the Strada Bianca Pro comes with a slightly thicker 260 TPI casing that should be more suitable for rougher conditions.
Picking the right version of the Strada Pro also can be challenging as it's available in a lot of different versions and sizes. This is a test of the most high-end Strada Pro HTLR version where the HTLR part stands for "Handmade Tubeless Ready". Also available is a "Handmade Clincher", "Handmade Tubular", "Vulcanized Tubeless Ready", and "Vulcanized Clincher" version. The vulcanized versions are a bit cheaper and come with a more standard 120 TPI casing.
The Strada Pro HTLR on test here comes with the 300 TPI "SuperPoly" casing with tan sidewalls and PPS anti-puncture breaker under the tread. We tested the 25-622 version but you can also get them in the 27-622 and 30-622 size.

| 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
- Challenge Strada Pro HTLR 25
(100% is best)
The Challenge Strada Pro HTLR is an overall strong performer in our tests but its main weakness appears to be wet grip of both the center and edge (cornering) of the tire. Although it's not the fastest rolling tire out there, performance at lower air pressures is relatively strong when compared to other tires. Puncture resistance is slightly above average and good enough for all-round usage.
If you don't mind the lower grip of this tire, or hardly ride in wet conditions, this can be a fine tire. If you're looking for tubeless tires with tan sidewalls we recommend taking a look at the Veloflex Corsa Race TLR (read our review) and Corsa Evo TLR (read our review) as they both perform better in our tests and are available with tan sidewalls.
