Our son came home for Father's Day and brought my '05 Specialized Dolce Comp, which I loaned him a couple years ago, with him.
Father's Day was also his birthday. So he borrowed cgallagh's Fuji and we rode the tandem; managed the kid's age +6. He crashed hard a month ago and is finally getting back into riding.
We went to the LBS and helped him purchase a new bike, a Fuji SL-something Pro. It weighs less than my Diva, has Ultegra components, and of the nearly-dozen bikes he rode, he liked this on the best.
After sealing the deal and riding the new bike home he brought in the Dolce... He crashed it at least once. Never cleaned it as far as I can tell. The 105 components are barely worth posting on eBay. My 5 yr. old bike, my first road bike in 25 years, is pretty much toast. There are a few parts -- front and rear derailleurs, crankset -- that we can try to sell. I'm going to donate the frame to the local police force organization that fixes and gives bikes to kids.
That bike took me from the "let's take a ride" cyclist to "let's do a century a month" to "hey, let's try a time trial" to an eventual upgrade and a racing license. While I was saddened to see it so abused, I knew that it had served a purpose: It got me and my son addicted to cycling.
Cgallagh took off the brifters and customized them for use as faux brifters for my stoker bars. It strikes me that this is akin to being an organ donor: Every time I ride the tandem a part of the Dolce will go with me.
