cannondale hybrids

Hello all! I have what appears to be a 1992 cannondale H400.. It appears well taken care of, has a few scratches...should it still be safe to ride it on the road?.. The reason I am asking is I have never had an older aluminum bike, I have heard aluminum doesn't last...and the cantilever dropouts look like an odd design..thanks for any replies!

First of all, if you're not comfortable working on bikes, have a mechanic at your lbs take a look at it. There's no reason to stop riding a bike from 1992 just because it's aluminum. Check the frame carefully for cracks, especially around the welds. Also check the rims for cracks, especially around the spokes.

Can you take a picture of the dropouts and post it here? Also take pics of anything that looks sketchy.

If the bike has not been ridden for a while, you might want to take a look at the tires and brake pads, or have a mechanic do it.

Hiya anyone with a Hybrid:

There is a battle going on to make Hybrids a variety of bicycle that is it's own variety. As is, posts about Hybrids are flung all over these forums. And they are also widely discriminated against. Want to lend a hand & voice to help us enact this long-overdue change?

Oh by the way - did you know the metal-cap on the Washington Monument is made from aluminum? It's been there since 1886. Taken many lightning-bolts since then. And it's doing fine. Thus far no one has been able to say aluminum will fall apart after 'x' number of years. Well - they say it, but not one shred of proof has been presented.

Tally Ho!

That cap doesn't undergo the kind of cyclical stress that a bicycle frame undergoes. Aluminum definitely does have a fatigue life, as witness by all the early Jetliner failures and the aircraft industry's extreme inspection measures. Specifically, in the bicycle industry, while most steel frames have a lifetime warranty, most aluminum frames are limited to 3 -10 years. If aluminum didn't have an endurance limit, we wouldn't have those restrictions.

Having said that, life span can be prolonged by over-engineering. In the case of a Cannnondale hybrid frame, I would have no concerns over life expectancy, provided it is not abused.

I hope my Cannondale hybrid does not fall apart. It's just way too much fun to ride! I'd get all teary eyed.
