I saw 40 miles and thought that’s a bit extreme for a MTB shake down, but then, oh yeah, roadie content again on Singletrackworld. Does anyone here ride mountain bikes any more? 😛
Just mocking 😉
Seriously, I guess so on a road bike. I’m no roadie, but sounds like a good test if you mean shake down before something serious (races?).
An MTB, I’d be taking to local trails with plenty of rough stuff but not take it too far from the car with tools in the car, or better take tools in bag to adjust things that make slacken or need adjustment on first ride (headset etc), not to mention a shock pump assuming it’s not a fully rigid. If freshly tubeless then prepare for potential leaks or blowing off rim, i.e. spare tube and pump/CO2.
