Our Robusta was $8300. With 2 sets of speedplays, belt drive, new stoker stem, new seats, Zipp wheels, ceramic bearings, we're getting close to $12,000.
For a fair accounting, though you'd have to back out the cost of some of the stock components (i.e. original seats, original stem, chain, timing rings.)
And the cost per mile should drop below $1 this year.
