Decks usually last 2 months at the most. I always like to try something new, I can get used to just about any shape, concave etc. but it has to be 8" wide, I've tried the 8 1/8, and the 8.25, just too wide for me. Trucks last a long time, I've never really paid attention, but at the least 6-8 months, these new theeve v3's might last longer though. Shoes, last me forever, at least 3 months. The only shoe I've ever had in 13 years of skating that blew out immediately were the fallen jack curtin model, the Capitol. Wheels, I skate those things till there completely dead, 3-4 months. And bearings I try to hold onto for as long as I can, I usually replace those individually.
