Maxxis Re-Fuse Gravel road bike tire on a rolling resistance test machine

The Maxxis Re-Fuse has been given this name because it refuses to puncture. The name makes it immediately clear what Maxxis has developed this tire for: preventing you from stranding somewhere with a flat tire. With a tire designed mainly to provide a very high puncture resistance, we do not expect a low rolling resistance. That doesn't have to be a problem as long as we know the trade-offs of this choice.

The Re-Fuse consists of a 60 TPI tubeless-ready casing, dual-compound rubber, and a layer of MaxxShield anti-puncture material, which must ensure a very high puncture resistance. The tread is a virtually slick design with only a very light diamond-knurled pattern. 


We already tested the Re-Fuse in the 25-622 size for the road bike section. This is a test of the 40-622 version which is made for gravel bikes.

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

36-40 = 45 psi/3.1 bar
Medium Air Pressure
30.8 Watts
CRR: 0.00923
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
Low Air Pressure
33.9 Watts
CRR: 0.01016
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
38.6 Watts
CRR: 0.01157
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


  • Maxxis Re-Fuse Gravel
Performance compared to all other CX/Gravel tires
(100% is fastest - lightest - highest - strongest)

The Maxxis Re-Fuse is by far the most puncture-resistant gravel bike tire you can find. Compared to the tires we tested so far, the Re-Fuse has almost twice the tread puncture resistance than the next tire. The puncture resistance of the side walls is a bit more in line with the rest, but certainly not bad.


As can be expected from such a puncture-resistant tire, rolling resistance is very high. Also, the grip on loose surfaces will not be great because the tire has a nearly slick, diamond-knurled tread pattern.


If your priority, however, is that you want to reduce your chance of a flat tire as much as possible, we consider that chance with the Maxxis Re-Fuse to be very small. Of course, for extra puncture resistance, mount them tubeless with sufficient sealant.
