NEW AERO v LIGHT WEIGHT Bike or combine the 2?
Moderator: robbosmans
Can you actually demo any of them? That's what I would do. There is no better way to determine what is best for you without riding them. You think you want aero for the watts saving but would you be happier with a light weight bike? The reverse is also true or a combo of both.
Don't make the mistake of your quantitative approach without considering the qualitative side or maybe more importantly which one turns you on.
I've ridden some aero bikes that don't handle well and some light bikes that are squishy.
Since the frame is a small part of the total package(considering wheels, helmet, bars, positioning and clothing) in watts savings then I'd focus on getting the ride quality you like and add the aero after. If its the aero frame then that's a bonus. The good news is that some new aero frames are getting lighter and more compliant and some light bikes are getting more aero. Still can't decide? Get the F8

Even a hi-end steel frame will be 500 grams heavier and at the same time much less stiff and responsive than a good 1100gr carbon frame.

Aero frames and nice paintjobs are cool but the reality is that neither does actually matter when racing.

Nice post!

Normally I would say aero or at least semi-aero but 1500m in 60km (25m/km) is a wicked amount of climbing. As a damn yankee I view climbing in ft/mile so please bear with me. My climbing scale is as follows:
50ft/mile (9.5m/km)-Rolling
75ft/mile (14.2m/km)-Hilly
100ft/mile (18.9m/km)-UGH
150ft/mile (28.4m/km)-WTF
With most of your rides falling squarely between UGH and WTF you have to go with the light,stiff and hopefully comfortable climbing platform. You can always add wheels to the arsenal later. In conclusion.... Scott addict!!!

Whichever has the best geometry for you.
Assuming that is equal which it isn't my rank list would go:
Non racer: Comfort, weight, stiffness, aero.
Racer: Stiffness, comfort, aero, weight.
Realistically comfort probably affects aero more than any other factor. I could also change the rank list for racer depending on the style of racer.

with your climbing to distant ratio you are basically doing hill repeats.. I would get a light comfortable climbing bike with bars with big reach and big drops so you can get into the most aero position for when your descending. / your rest day.
Are you going to ride tubulars or clinchers?

Narrowed it down. Have decided to go the "lighter" over the "fully-aero" options. I think the nature of the climbs I do and frequency would warrant a lighter over an aero bike. I have narrowed it finally to the following:
1. C/dale Supersix Hi Mod
2. Ridley Helium SL
3. Scott Addict SL
Do any of you know about any "warranty" problems that affect these frames?
Apparently Cannondales suffer alot of BB problems???

You have seen this thread, right?

If not, give it a read. And ignore the obvious trolls. As BmanX said, you can have aero and light (hint: he's built them, so is evidence that it can be done).

I don't mean to be a "troll" but I'm going to suggest that aero and light might not be all you want. I think too many people get caught up with the numbers of weight and aerodynamics, where some things that can't be measured are much more important. For instance, how does the bike handle, and does it suit what you want to use it for? Is it comfortable?
Now I'm sure guys like BmanX have thought about all of these issues lots, and their bikes obviously suit their intended use. But it seems to me like your intentions are different to BmanX, and hence you may be better served by a different style of bike.
I'm not saying you won't be faster on an aero, light, and stiff bike, but I'm just saying if it's no fun to ride you're not going to ride it. Obviously guys like BmanX enjoy riding their super bikes - but if you're not looking for all out speed you might have more fun on a different machine. And if you're not riding you're not going to be fast no matter what machine you're on. Try a few, ask owners what they think of them, and what style of riding they do. I can't remember which user this was, but I recall someone on the fairwheelbike forums having a very similar build to BmanX and switching to a Colnago. Now I don't know the full details about why he switched etc. but just some food for thought.

I agree with your points. As mentioned, you can have both and do it fairly light and aero. One point to mention is that I also have a very light steel build that is not aero but light. It has different dimensions as I use this for my Gran Fondo rides and rides with my GF. When I am out with the boys or doing a fast ride, I am on the Cervelo. The bike is a rocket but the Custom English Steel is a cruising dream.

Amazing real-world test results here http://www.cyclingweekly.co.uk/news/lat ... deo-176312
Can it really make that big of a difference? Too bad they didn't use the same wheels on both tests. The wheels probably made most of the difference.

It is a good comparison, but a better comparison would be using the same wheels as Mavic R Sys have to be some of the least aero wheels.
The Velodrome is a good place for some testing, but riding the two bikes over the same undulating course would be more real world, as s velodrome has a very smooth surface and no hills, where the lighter bike would gain some time.

Yes. That test is easy enough to replicate and only requires a power meter and patience to get good quality data. I have both a Cervelo S3 and a Felt AR. Doing the Chung Method Test my data corresponds and verifies similarly to what Cervelo and Felt have published as well as others. Compared to my CAAD10, the S3 and AR are significantly quicker. My own personal data supports that statement.
