Calling BS.Hugor said:Easily steel. Aluminium is the harshest by a long shot. If you've got the dough then go titanium. As mentioned get some large volume tyres live the Schwalbe big apples for the city or WTB Weiwolfs for trails at 25 - 30 pressure. Any more comfortable than that and you may as well be on an armchair.
That is my experience on my road and mountain bike as well. I recently changed from a steel Karate Monkey to an cheap aluminum Access 9r from Performance. The Access is IME more compliant.simenf said:Comfort in frames is all about the design and build, not about the material.
For added comfort look at large volum tires, low pressures, thinner seat posts and a fitting comfy saddel. As stated before in this thread...
I have to disagree based purely on frame material. The compliance of "steel" frames per se is an urban legend. Tires, assuming they are not inflated to ridiculous pressures, have far more compliance and would mask any vertical frame flexing.MendonCycleSmith said:See what not asking a properly worded question does? You make a bunch of folks give you more confusion than you started with.
Is steel more compliant than the other material? Yes, all day long (unless you mean some crazy cheap, thick walled POS). Thin walled butted steel has a ride with no equal in terms of forgiveness and snap.
Is aluminum stiffer, therefore, less flexible, and thus, capable of building a less compliant frame? Yes (unless you mean some of the uber-expensive offerings that have aluminum pushed to it's limits, often with carbon involved, or things like Scandium). Cheap, thick walled pricepoint type alloy frames are like riding with a jack hammer up your arse.:eekster:
Comfort is so many things. Back pain, butt pain, shoulder pain, hand pain, they all have different solutions, (fit, component choice, design, body type, fitness level etc) .
But to call steel no different in ride quality than aluminum is a disservice to the OP, and the material.
That's the part that depends on bumpiness.prphoto said:So let's say hypothetically, that you had 2 bikes one a steel hardtail and one aluminum and they had the same geometry and same wheels tires etc. that they would feel the same?
