I have multiples of everything. I could rebuild a bike several times with all my spares. I have spare wheels, bearings, stems, cranks, pedals - you name it, I have it. I have rows of tires, boxes of saddles, drawers of cables.

Much of it was salvaged from all the bikes I have had to part out over the years, but a lot if it is new in the box stuff.

I commute by bicycle and always liked the fact that if anything ever went wrong with my ride, I could tote it into the basement and have her ready for the commute the next morning.
