I was on the Surly website looking at their bikes, and I was considering possibly building my next "new" bike, some time in the late future. And then I realized that all their bikes were 4130 Cromo. I thought "well my 11.8 is made out of the same stuff, why not slap some higher quality parts on it?" But then I was looking at an article on their blog about caring for a steel frame and in the first paragraph they state "steel has a special ride, snappy, comfy. With a bit of care, it'll ride the same in 10 or 15 years as it does now." Wow you don't say, a whole 10, and hey if your really lucky 15 years, until it turns to junk?! So what do you all have to say about that? Is a 4130 Cromo frame's prime only up to 15 years, and then what? I find that "fact" hard to believe.
Also, on a side note, I was hit on my 11.8 a couple months ago, and though I don't see any damage to the frame is it possible it still could have weakened it?
