Bontrager R3 Hard-Case Lite TLR road bike tire on a rolling resistance test machine

According to Bontrager, the R3 Hard-Case Lite TLR is a tubeless-ready road bike tire designed for speed, traction, and durability for everyday riding. Bontrager's description fits well with other tires that we categorize as all-round road bike tires like the Continental Grand Prix 5000, Schwalbe Pro One, Michelin Road, Vittoria Corsa, etc.


The basis of the R3 Hard-Case Lite TLR is a 170 TPI tubeless-ready casing with an extra layer of puncture protection material under the tread, which is a well-known recipe for an all-round road bike tire. The "TR-Speed" compound is developed by Bontrager itself, has a hardness of 60a, and should roll very quickly according to Bontrager.


The R3 Hard-Case Lite TLR is available in the 25-622, 28-622, and 32-622 sizes. We think this is a good size availability for tubeless road bike tires as some cyclists are really looking for the 32-622 size for more comfort and better sealing capabilities if you do have a puncture.


Bontrager claims the R3 Hard-Case Lite TLR is easy to assemble and inflate because it should work perfectly with its own wheels. Unfortunately, we don't have a Bontrager wheel available to test this. On our standard test wheel, the tire went over the edge easily, but inflation was impossible without a compressor and the valve core removed.


Let's see if the Bontrager R3 Hard-Case Lite TLR is worth checking out at all if you're not completely tied to Bontrager...

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.

We're not impressed with the Bontrager Hard-Case Lite TLR. In almost all of our tests, the R3 Hard-Case Lite TLR comes out as an average road bike tire. If we also take the high price Bontrager is asking for this tire into consideration for our final judgment, it is better to pick a tire from another brand. We only recommend this tire if you're tied to Bontrager or have some nice Bontrager wheels and want to stick with Bontrager tires.


Although the R3 Hard-Case Lite isn't a stellar performer in our tests, there is a reason for celebration as it's the 100th road bike tire we've tested since we started this website back in 2014. If you're looking for some road bike tires, we recommend you to visit our road bike overview where you can compare the R3 Hard-Case Lite TLR against 99 other road bike tires.
