I am due to change the sprockets and drive chain on my Pulse Adrenaline and have come across a 17T front sprocket that should provide approx 13% extra top speed for a loss of 13% torque whilst using the standard 51T rear sprocket. Has anyone tried this?

To be honest, the more I think about the less I want to try it. Perhaps its more torque I need. /boggle.

Bjonk.
