Serafino said:I've actually riden a lot of carbon. My first carbon bike was a Peugeot in the mid 1980's (used in the TdF by the Peugeot team and ridden to great effect by Rober Millar). Not much carbon back then I assure you and it feature carbon main tubes and an Alu rear triangle and Simplex gruppo.
Lower price carbon from Tiawan is just that ... lower priced carbon. There is a reason that many lines have several grades of carbon in their line up. All carbon, like all Alu, Steel, Ti, etc., is not the same.
My point is that at the high end, Steel is very, very close in terms of weight (down to 16 lbs certainly), ride quality (some would argue its superior), to Alu, Ti, and Carbon. The issue with carbon is longevity (still too early to tell really) given the expensive of a mid end or high end carbon bike.
The ProTour bikes have little in common with your 2000 USD Carbon bike. I'd say that carbon is probably, once you amortize investment, easier and cheaper to spit out in mass production at the lower end that high quality steel or aluminum.
Let's not forget that the ProTour was won on an aluminum bike last year (Bianchi's FG Lite) and many teams still use Alu when its required (CSC's Soloists, Lampre, Liquigas, Phonak, DL, etc.).
Carbon's great, but if you are a heavier rider (even 175 lbs qualifies) and want a longer term investment, I'd also investigate high end steel and aluminum personally.
Lastly, its not the bike .. its the rider. 🙂
Well, we are in agreement that Al and steel still make fine frames, and certainly races can and will be won on Al and steel in the future. But for the weight-wienie set, strong, stiff and durable CF frames are now on the market at 1 kg or less. Al may be close, but no steel frame I've seen is in the running below 1500 grams. Not that it matters to most of us....a full water bottle weighs 600 g.
As far as longevity, personally don't think it's an issue for the average (non-racing) recreational rider doing maybe 3000-5000 miles a year. After all, millions of older CF frames and forks are on the road everyday now.
On the other hand, strong high-mileage racers will break anything in 2-3 seasons of hard hammering. I know a couple on them that have been through over a dozen frames; steel, Ti, AL, CF....doesn't seem to matter. One ex-racer still rides an older 5200 Trek frame....he got 2 warranty replacements before Trek got wise and cut him off. (Like all major brands, they don't warranty against fatigue or "normal" wearout).
Bottom line for me: get the frame material you like. Very high-quality CF frames are coming out of the big Taiwan factories now, but if you don't care for "plastic" bikes, then you have other great options. FYI, I have a couple of Raleigh steel 531 bikes (not high-end), but now ride a locally-built Al frame with CF fork and rear stays. Would like to try a super thinwall steel frame (eg, True Temper S3) sometime.
