What is the best grade of aluminum for road bikes?

Question

I am looking to purchase a road bike and i see all different grades of aluminum, but I don't know which ones are better than others.

Answer 1

That's like of like asking which is the best coffee. There is going to be a lot of disagreement because The material matters just as much as how it is built, so what do you like on your pizza?

Keep it in the big ring.

Answer 2

You will get many different views. Anything above 6061 will work for your needs.

Answer 3

There really isn't a "best" grade. They all have different riding characteristics and different strengths and weaknesses.

Ride a couple of bikes and discover it for yourself!

Answer 4

6000 or 7000 series Al alloy

BUT, note that aluminum has a reputation as being very stiff and unforgiving: undesirable characteristics for a touring or long distance racing bike. While this obviously relates to frame design as well as material, you may want to consider -- depending on price range and your intended use --whether aluminum is the best material for your next bike.

You will find as many opinions as cyclists, I would suggest carbon fiber, titanium or steel are all preferable to aluminum.  That said, aluminum is probably the best choice for the $500- $1000 price range though.

Answer 5

6061 is  a very common one (along with 6011 and 6013)....they're durable and have good working qualities for the welders.   7075 is also common.....it can be made into a lighter weight frame and will cost a bit more.   A few mfrs are using a scandium alloy (higher percentage of scandium in the aluminum mix)....those are very light frames, but pricey and they have a short lifespan.  

For most general road riding, it really won't make a difference unless you're going for light weight....in which case you should be looking at different materials anyway.   Keep in mind that whichever metal your frame is made of, the manufacturer has probably designed the tubing and frame with the characteristics of the material in mind.....so don't worry too much about it.  Pay a little more attention to the geometry, sizing, and components that will come on the bike.  Those will matter a lot more to you as a rider.  

Hope this helps.....happy shopping!  :o)
