Although the normal BB shells for sell are excellent for singles, etc., I went looking for something a bit stronger for heavy touring bike builds and for toring tandem builds.

I was pleasantly surprised to find a nice set at www.AtomicZombie.com

Part Number: BBRAC_Steel_Bottom_Bracket_2Pack_Part

Cost: $28.95 for 2 pack + $8.80 shipping ...or basically $19 each delivered.

Much thicker and better machined than most shells I have used/seen. When they arrived, I also noted threads were deep, clean and unusually well cut.

Here are pix;



Appreciate thoughts and/or other sources for building bits.
