The cost per kilometer (includes purchase price & upgrades) of my bikes:
1983 Kuwahara MTB (stolen 2008)… 1.6 cents/km
2004 Giant OCR3 (sold 2009)… 5.0 cents/km
2008 Redline single speed flip flop… 23.0 cents/km (so far)
2009 Colnago Strada SC… 38.0 cents/km (so far)
I’ve decided that I’ll try to follow the rule that I can’t replace a bike until I hit the 5.0 cents/km return on investment (ROI) threshold. Only 61,000 more km’s to go on the Colnago (approx 11 years at my average seasonal pace)! Of course, a new MTB would not be a “replacement” bike that would be an “additional” bike and that’s a whole other rule…
On the topic of MTB’s, this is a link to a very cool video that a colleague sent me. It’s a four part series, although I’ve only watched part one.
What’s your best ROI on a bike? I bet Jim or Pete have a ride that’s in the range of 1 penny per km….
