Well, let's see....

$30 for a new fork spring (needed, as the weaker old one pitched me off the bike, breaking my c-bone in 5 places); $70 for a new rear shock to replace the failed OEM.

$40 for new cables after 2 years; 12 tires (some went on other bikes in the family cuz I didn't like 'em, but I used up 8, including the two still on the bike), total cost there about $260.

$400 after two years, which doesn't count upgrades (saddle, crank) or chain lube; I do need to add $50 for a new cassette/chain.

I spent more than $450 on gas & PLPD in six months! And that was before the spike in gas prices!

I think I'm money ahead....
