Although I just a bought an XCL (review pending my Bootleg trip this weekend), I am already eager to lust over something else.. so where's that steel 29er frame that's been rumored...... I heard there's some "inside" guys on this forum :thumbsup: .
Aluminum isn't actually stiffer than steel. Steel has a higher modulus than aluminum and as result frame makers use thinner steel tubes analagous to thicker aluminum tubes. This means the cross section of steel tubing has generally has a higher area moment of inertia than a thicker aluminum tube of comparable strength. The higher the area moment of inertia the higher the slenderness ratio - the key factor in what we percieve as stiffness.ChumbaJason said:Aluminum is generally stiffer than steel. Both have unique quality's. :thumbsup:
