Last torty minutes of my ride I came up with this theorem
Casette for jobbers like me should be convex, not concave

No, retard, you do NOT need 11-12-13-14 for your sunday schnitzel ride with you're retard friends
No, retard, you can't tell a different if you score 2.45 rpm less at exactly 34 km/h

Instead, I need a fluid sailing and FOR SOME REASON majority of my rides fell in the category where BIG ring - 6-7 cog is optimal, but it starts to rattle, and SMALL ring - 4-5th cog is optimal and also starts to rattle

I think the bike industry has been held captures by boomers who refuse to give up the low cadence meme (despite the fact they won't be able to sit up from they're couch at 50)
And also jobber who think they ONE DAY gonna make a BIG race and HIHG speed

FUCK
