We Tested Gravel Equipment In A Wind Tunnel And The Results Were

We Tested Gravel Equipment In A Wind Tunnel And The Results Were We took my gavel bike to the wind tunnel and tested a lot of the aero questions that gravel riders have like tires, packs, on bike storage, aero bars and mor. This article summarises an aerodynamic comparison of 3 different gravel wheelsets and 3 different gravel tires. swiss side tested the gravel wheels in the full size wind tunnel and explained the aerodynamic gain or loss for each rim depth and tire width. we used the schwalbe g one and the cervèlo aspero.

Experimental Equipment Of The Wind Tunnel Test Download Scientific Before testing the wheels in the wind tunnel, we run a tare run. this allows us to calculate and compensate for the drag caused by the fixture used to hold the wheels in place. this “tare value” is then removed from future tests so we have accurate aero results. then, we set tire pressures for each wheel using an ashcroft pressure sensor. Swiss side publishes wind tunnel results for gravel tires. schwalbe, continental, wtb, vittoria, and panaracer gravel tires measured for aero drag in german wind tunnel. i don’t know if they’re well suited for gravel, but i do know if you take a gp5k 32mm tires & put them on a flo g700 gravel wheelset it’s very, very aerodynamic. Cervelo aspero with swiss side gravon 250, continental terra speed tr. 40mm tyre, 3.0bar pressure. for making the comparison, two typical high performance road and gravel bike setups were measured in the wind tunnel at 30, 37.5 & 45 km h. rolling resistance data is representative of on road riding in order to make a direct comparison. Velonews recently completed a lab test of rolling resistance for 24 models of gravel tires at wheel energy in finland. join velonews today to read the full results of that test. this is just one of many gravel tire studies swiss side published on its site. schwalbe, continental, wtb, vittoria, and panaracer gravel tires measured for aero drag.

After a round of testing at the arc wind tunnel to determine the most beneficial rim tyre combination, johnson selected reynolds black label 60 expert road wheels that feature a 21mm internal rim. We soon learned there wasn’t a real answer. after hours of research, computational fluid dynamics testing, and a trip to the a2 wind tunnel, we now know what makes a cycling wheel aerodynamic. below are several paragraphs discussing how we designed our flo cycling wheels and of course our w ind tunnel results.
