I am reading the Shimano specs and I cannot figure out what is the "top sprocket". An example: https://bike.shimano.com/en-EU/product/component/sora-r3000/RD-R3000-SS.html



"Low sprocket" (I couldn' tell what it is, but the value is more meaningful) describes the rear sprocket, ok, "Total capacity" this I understand as well, but what is "Top sprocket" with min/max values 11/14T (accordingly)?






derailleur sprocket

          In that context, Top sprocket is the smallest one on the cassette, which gives you the Top or highest gear. (You would think they would match terms Low and High or Top and Bottom.)

          • Specifically, the smallest cog on the cassette is to be from 11 to 14 tooth. You can't have a smallest cog outside that range. There's a similar restriction on "Low sprocket" being from 25T to 32T.

          Refactoring coordinates for Minecraft Pi buildings written in Python

          Image
          0 $begingroup$ I'm fairly new to coding and I wrote this script in Python for a house with a roof in Minecraft Pi. I've found different ways to write the coordinates to make the code base shorter, but I'm wondering if it is possible for me to refactor it any further so I don't have to list each coordinate line by line. import mcpi.minecraft as minecraft import mcpi.block as block mc = minecraft.Minecraft.create() p = mc.player.getTilePos() mc.setBlocks(p.x+1, p.y, p.z+1, #Main structure starting coordinates (DO NOT ALTER) p.x+19, p.y+4, p.z+6, #Structure size/coordinates (Alters cube size) block.STONE_BRICK) mc.setBlocks(p.x+2, p.y+1, p.z+2, #Hollowing out main structure interior p.x+18, p.y+3, p.z+5, block.AIR) mc.setBlocks(p.x, p.y...
