Belts 9mm or 15mm?

[Chief Hedgehog]

4607 typically uses 9mm when we use belts. In 2016 we used them with no problems. However, there was no reduction; just strictly transfer of power (1:1 ratio). We purchased extra belts and even though we sheered a few drive shafts, our belts were never a problem. And we played in some pretty tough matches throughout the regular FRC season and in the offseason (looking at you 2052 and 5172).

Maybe this year if we have the room (we won't) we will try out the 15mm belts and pulleys we bought so long ago...

Good luck!
