I'll be needing to change brake pads soon on my 2020 Rad Rover step through. I first checked at Rad and they want $13 per set and it doesn't appear that includes a new spring. On top of that they want a whopping $15 to ship them to me. So I looked on Amazon and Ebay and found lots of Tektro Aries E10.11 brake pads with springs for good prices and free shipping but the other numbers didn't match the A30 and IC344 shown at the Rad site. So is the E10.11 the important number and as long as that matches I'm good?
