Re: Longtime lurker, first time poster
It has been a couple years and I learned something about internally gear hubs:
Sram is the way to go.
Sturmey Archers and Shimano 5 and 8 speed hubs DO NOT like to be shifted when under a load. Both manufacturers tell you to stop peddling THEN shift. This is a bit of a challenge with the SBP Shift Kit. I burned through 2 SA's and one Shimano.
The Sram 8 speed CAN be shifted under a LIGHT load. AKA I let off the gas, shift, then back on the gas. 2 years later and this thing is rock solid.
