I have seatpost, bb spindle, and every single nut and bolt in titanium...I did have a watanabe seat with titanium rails and stimulatorz pedals with titanium spindles.When i ditched the pedals i kept the gold TiN coated spindles incase they fit other pedal bodies.
what killah said is true. the hardware swap is best for rust resistance. a little ti anti seize helps.
posting pics on this forum is literally a chore. Sorry man.
