On typical South African XC and marathon terrain, like in Jonkershoek Stellenbosch where the Cape Epic and Origin of Trails events pass-through is a 100mm or a 120mm bike faster?
With various Strava segments setup around a 2.82km lap to time
Yes there are many variables to these kinds of tests and we want to reiterate here that these are real world conditions and not a science lab. Although the section of singletrack on the test loop may look very technical, it is an actual piece that the Cape Epic uses and is as such a real race course.
The test track is 2.82km long and two flying laps were done on each bike. Per lap the climbing portion is 1.11km, the flat section is 750m and the descent is 900m of 100% singletrack. The total elevation gain per lap is 115m. The average heart rate on both bikes is within 2%. If any brands want to come forward and offer us a power meter for future testing please feel free to reach out to us. Enjoy!
