The two speed always seemed a bit gimmicky in the TF2 – I’ve never noticed any increase in torque in the lower gear and what with the ‘slop’ from the gearbox and drivetrain you can roll/coast two inches with the drag brake on. I set it so it’s basically in top gear the whole time.
Probably the most pointless upgrade…. ….in the world. (sorry, it was the mention of Top Gear)
