I haven't seen the figures on the old Reynolds hoops, but I think they looked more aero than they actually were.

BTW, the only reason I won that day was because I didn't get caught in the final turn pileup. Sometimes it's better to be lucky than good.

So what you meant to say is that not all aero rims are equal. No argument there.

No, I guess between work, racing and helping to put on a NRC race, I totally missed all the tech on wheels.
I focus on training and learning how to race. I have 4 sets of wheels for 2 road bikes, which means I'm probably not that sharp considering I can only use one set at a time. I often wonder why I have 2 more cx bikes, and 2 mountain bikes when I only use those a few months out of the year. Yeah, not that sharp I guess.

Why don't you educate us all.

If all of you were really so hardcore you'd be stripping the paint and decals off your bikes and riding in skinsuits ... :D

For the OP's question ... well that has long been answered. Now we are back to "If a difference exists but is imperceptible, how can we be sure whether it affects and outcome, and by how much?"

The answer is, it does, but no one can tell how or how much ... it's imperceptible.

Did you win the race because you saved .007 watts with your aero water bottle? ... or did he catch a breakaway early, which failed, while you stayed back in the pack and waited for the winning move? Or was he actually faster and stronger (and lighter and more aero) but you just threw your bike better at the line?

Way too many variables. Maybe his wheels were more aero but there was a slight crosswind which made them drag a tiny bit more ... or maybe you ate that last gel at the right time ... or maybe you took a slightly smoother line around a couple corners every time and didn't have to brake and thus accelerate as much, or maybe he took a more efficient line but didn't taper down his training soon enough and wasn't on peak form? Or maybe his allergies were acting up that day. Or maybe you werre the better rider despite him having the better bike and you just outworked him ... or maybe he was the better rider but your aero bidon was too much of an edge for him to overcome ... or maybe he got cut off at one corner and wasted precious time being angry about it and lost focus and you on the other hand stayed positive throughout ..

Or maybe you took that apocryphal pre-race trip to the rest room and were a pound lighter and felt fresher.

Or maybe you knew your wheels were more aero and that perceived equipment edge gave you the confidence to perform at a higher level than usual and you won because you imagined your wheels were going to make you win.

All the studies in all the labs in the world cannot possibly cover all the variables. Otherwise, no one would have to race, they'd just weigh their bikes, list their equipment, input it all into the master computer, and read the printout to see where they finished.

What it all comes down to is ... get the Zondas, OP, they will serve you well.

Yes, simmered down now.

There's a lot to unpack here, and I don't really know where to start, but I do think it's important to make one point absolutely clear: performance gains derive from your effort, not the equipment.

You could have the lightest, most aero bike in the world, but if you're not pedaling it, it's not going anywhere.

If you enjoy going out and putting in hard efforts, and improving those efforts in terms of distance, speed, and time, then there is no reason not to avail yourself of the designs and tech that will help you do more...to the extent you can afford to.

And that's the crux of the question: how much is having the equipment which maximizes the results of your efforts worth to you?

Some here want to answer that question for you. They want to get into your business and tell you how you don't deserve the best equipment because you're not an "elite cyclist" or a "racer," because, well, your desires are simply not worth as much as theirs are. It's a load of crap, all that.

Despite what the haters say, there is no legitimate question about whether aero wheels can confer benefits. They do...period. The questions revolve around how you ride, what you want, and what you're willing to pay for.

Do a casual 5 mile out-and-back down a crowded esplanade? Deep carbon wheels are awesome for that; they roll and look good. Is rolling and looking good worth $1.5k to you? If so, that's the only thing that matters.

Do hard efforts on a regular 32 mile loop and like seeing your accomplishments in Strava? Deep carbon wheels are awesome for that, too; they'll help you eek out extra speed when you're hammering, and help you hold speed when you're recovering. Is saving a second on your favorite segment and moving up the leaderboard worth $1.5k to you? If so, that's all that matters, but the wheels still look good, too.

The bottom line is that you are very likely to realize benefits, and very unlikely to lose anything, by going with an aero wheel set, so why not equip yourself if you can afford it?

If letting other people-- jealous, self-loathing people-- tell you what you what your expectations should be, what you deserve, and how you should spend your money is important to you, then forget the wheels. Just f*** it all and drink up the Hater-ade at their bitter party.

Wow. That is some rant.did you read the OP? That
He specificall said "I felt the price bump for a lighter wheelset did not make sense"
Later, he said "Am I correct on my weight vs performance weight thought? Would like your thoughts on this.. "
The OP was asking for guidance and opinions. In addition, his first line displayed that money was factored into the equation.
Thus, any posts stating that the weight or aero were not worth the cost are warranted. By the same token, those that said the opposite are warranted as well. The OP solicited an opinion and so what if there are differing ones.
I have no problem with anybody that wants to make their own buying decisions. It is their money. This poster requested an open dialogue though.

In response to the OP, I am not sure your weight is all that relevant here in the decision. One thing to consider is the benefits of carbon wheels are greater at higher speed due to the aerodynamic factor. At higher speeds you will see greater benefits. If you average 15-18mph on your rides, you will see less benefit then if you average 20-25mph on your rides. You should still see some benefit in acceleration though.

I have met plenty of really fast cyclists that could stand to loose 20-30 lbs. I would not make that the reason not to buy the wheels.

Not one person reading these forums is going to increase their average speed from 15-18 mph to 20 - 25 mph simply because they buy a carbon wheel set.

And to add to that, not one person on this forum has made that statement (including the quoted poster). OTOH, your statement is quite correct.

I think your understanding is weak, and I disagree with your conclusion. Sorry.

What's the question again?

Maelochs 12-22-15 10:37 AM

The answer is that either set of wheels will work out fine for the guy, and the rest of us just like to squabble.

The OPs weight condition is that he weighs 180-190lbs.

At 190lbs or under, there are very few wheelsets that would not be able suitable.

Yep.

Don't overthink it. If you want it, like it, then buy it. Most importantly...have fun riding them.
