Well, as long as we’re talking about materials, I’d like to ask a question about aluminum. I’ve heard it’s more comfortable for heavier riders than for lighter ones. At the same time, I’ve heard it’s not the material that matters, it’s what’s done to it that affects ride quality the most. I’m starting to look at a new bike, and a lot are aluminum or aluminum/carbon which concerns me as I’m about 130lbs and my current bike (albeit a low quality frame and no carbon fork) rattles me around quite a bit. I’m looking for a pretty light bike, which seems to be where aluminum excels for the price.
