Opinions wanted. Carbon or Aluminum?

Question

It's time for a new bike and I don't know enough about the pros and cons of aluminum vs. carbon fiber. I can get a low-end carbon bike or a high-end aluminum for about the same price, so the budget is not really a major issue. Any opinions would be appreciated.

Answer 1

If you're going to get carbon, get a high-end frame....either as a complete bike or one that you build up with possibly non-top-level parts if you're concerned about money.  

I prefer aluminum for mountain bikes, steel for jump/urban bikes, and carbon for the road.  A good aluminum road frame is still nice to ride but carbon is really sweet on pavement.

Well-made carbon will minimize flex in the wrong areas, but leave enough compliance to give it a nice road feel.  Well-made aluminum will always be a bit harsh on a road bike but can be made darn close to the same light finish weights of carbon, especially if you choose a scandium frame.  The disadvantage of carbon is its relative fragility.  If they get damaged beyond superficial scratches, they're destined for the "lightweight and expensive" dumpster most of the time.  It's possible to repair damage to carbon, but the repairs are so expensive it's usually not even worth it.  Aluminum can be repaired more often, but they're often trash, too.....depends on the frame.  

Don't rule out titanium from the mix unless you have something against it.  Not as many offerings in the marketplace, but that's mainly due to it's expense and the training involved in working with it.  Titanium rides are pretty sweet.  

Hope this helps....enjoy the new bike whatever you get.   :o)

Answer 2

Answer 3

the cannondale rush 3 is a good aluminum bike for a reason price

Answer 4

Just a little personal story here.  I recently bought a new old stock Carbon Giant TCR Limited at a great price, did some wheel upgrades and the like then took it out for a ride.  The difference between that bike and my Colnago  Aluminum Dream (still have it) was amazing.  The whole ride quality, smoothness and climbing ability of the CF bike was supierior to that of the Colnago.  Or was it just the novelty of the newness?  Sure the two have different geometries and gearing but I feel so much more comfortable on the CF giant for long (over 50 mile) rides then the Al. Colnago.

Test ride them both, you'll see.
