WTB Nano TCS Light road bike tire on a rolling resistance test machine

The WTB Nano is a gravel bike tire with a tread pattern that should be good for a broad range of conditions. When we compare it to the WTB Riddler that we tested a couple of weeks back, the Nano has a much more widely spaced tread pattern with much bigger knobs in the center of the tread.

When looking at the specifications of both the WTB Nano and Riddler ,(read our review) it's easy to see these are very closely related. The versions of the Nano and Riddler that we've tested (TCS Light) both use a tubeless-ready, single-ply 60 TPI casing, and Dual DNA compound.


We've tested the 40-622 "TCS Light/Fast Rolling" Nano with tan sidewalls. The version with tan sidewalls is a bit lighter which is why we choose it over the version with black sidewalls.

Rolling Resistance
Real tire width in mm:
30-32 = 66 psi/4.6 bar

Rolling Resistance
Real tire width in mm:
30-32 = 44 psi/3.0 bar
33-35 = 40 psi/2.8 bar
36-40 = 36 psi/2.6 bar

Rolling Resistance
Real tire width in mm:
30-32 = 33 psi/2.3 bar
33-35 = 30 psi/2.1 bar
36-40 = 27 psi/1.9bar
Extra Low Air Pressure
32.3 Watts
CRR: 0.00968
The CX/Gravel 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


  • WTB Nano TCS Light
Performance compared to all other CX/Gravel tires
(100% is fastest - lightest - highest - strongest)

The WTB Nano performs reasonably in the rolling resistance tests when we take the tread pattern into consideration. Just like the WTB Riddler, the Nano gets a points reduction because of the sub-par puncture resistance of both the tread and sidewalls. If you do a lot of gravel riding and get cuts regularly, look for something else.


Rated 3 out of 5 as we think this can be a decent tire if you're riding somewhere where punctures and cuts are not that common. Visit our CX/Gravel overview page to compare for yourself and pick the best tire for your conditions.
