Sure, as unlikely as that seems, a high quality modern Aluminum bike will be a future classic. The question is can you ride them for 15 or 20 or 25 years, and reasonably expect that they will have functional frames for a future investor? I have heard from many, that the answer is no. An aluminum frame has a very limited life expectancy. Now we all know that the combination brake and shift controls have a life expectancy of (no kidding) six months of steady use. Those plastic seats will hold up in some fashion for a decade or two. The double pivot brakes will last a century (or as long as the single pivot side pulls). The rims will last a long time. The chains, cogs and such will need to be replaced constantly to make those 9 and 10 speeds work. So here comes the future collector, in the year 2020, and spots a classic, Canondale Cad5 STI with Rolf wheels. The price seems low at only $25,000 but it has a few problems. One problem is that both STI levers don't work. That's OK, he was able to hoard away two sets at only $1,000 per. (Perfect, that will give him a year or two of carefree shifting-braking before he needs to scout out other sources.). Problem two is more serious: The frame is disintegrating, and the bike really can only be used for display purposes. Does this sound like a future collectable to you? Garth Libre
