Hey guys, I often see lots of people upgrading their P Line from 4 speed to 7 speed, some via 7 speed external while some via the internal wheel set.
What’s the key differences? And for existing owners that have done some mods, does upgrading to 7 speed allows you to maintain at a higher average speed?
If there are any cons (aside from $$$ it costs to upgrades), feel free to kindly share them! 😊
