Review on SHIMANO Altus Right 7 Speed SL M315 7R by Brandon Guidroz

Great upgrade to OEM switches. Used them to help my wife shift gears on her new electric bike. Their small hands and short fingers made it difficult to push the button on the seven-speed Shimano OEM derailleur that was on the bike. Using a lever instead of a button, this shifter simplifies shifting because it requires less effort to shift and pushing instead of pushing results in upshifts. In general they work great. Doesn't quite fit due to bike manufacturer's component choices (not a Shimano issue) but they are very easy to install and work great. Very responsive and easy to switch.
