hand built
36h front and back
velocity aerohead and aerohead OC
white industry h2 front and h3 rear hubs
sapim cx-ray spokes
sapim brass nipples

any thoughts? (i weight 200lbs)
i like idea of mixing bladed spokes with traditional low profile rims with high spoke count for max strength to weight ratio.
i've never used bladed spokes, but i understand that aside from high prices, theres no reason not to use them.

another possibility i considered was 24h/28h with deep V, but I wonder if the increased moment of inertia/overall weight/high spoke tension are too much of a tradeoff for the tiny aero gain. the aero gain from the cx-ray versus some dt revolutions is probably tiny too but the only tradeoff is cost and I plan to keep the wheels for as long as possible.

I understand the aerohead is a good rim and you can't go wrong with White hubs. I know a good wheel builder who swears by Sapim cx-ray spokes. 36 spokes are more than enough for 200 lbs. I would say as long as you have a good wheel builder, it's good configuration.

Tom Stormcrowe

No, that's not a good configuration for a 200 pounder at all......it's actually under the excellent category. That will be a set of wheels that would stand up to riding the cobblestones in the Paris-Brest-Paris race or the Roubaix with a 200 pound rider.........

Do you need to ask???? Just remember, don't mix up hand built with "competently" hand built! Whoever builds them should really know what their doing.

What about the aero loss from having so many spokes. Where do you plan on riding? Like Tom said, this sounds like when crazy ass wheel, is it going on a touring bike or something?

thanks for the responses,

I actually intend to use these wheels for everything, from training to racing.

I proposed such a build because its different from the common factory clydesdale performance wheel of deep rim and low spoke count. Those wheels seem to sacrifice everything for the sake of aerodynamics. The strength argument isn't there.

The proven clyde wheel config includes BOTH deep rims and high spoke counts (deep V, 36 or 32H, 14g spokes).

I think wheels with low profile rims with a large number of bladed spokes present a nice compromise.

deep v's for clydes aren't about the aerodynamics, it's about the fact that there is more material in the rim and the rim itself is stronger and more durable. For std sized riders,they are trading off weight for improved aerodynamics. deep v's won't help them if there is a lot of climbing but the aero advantage is more important than weight advantage on the flats.

Mr. Beanz

Ya know! Going against al the too heavy myths aginst Deep V's being too heavy to climb, I don't buy it! I've used other rims and they are just too soft and mushy for my taste. The Deep V IMO is a stong sturdy stiff durable rim that makes it responsive on the climbs. When I pound the pedals on other rims., I feel the flex and loss of enrgy on a climb. When I stomp on a Deep V up the mtn, the wheel just responds to the pedals.

So eventhough it's consdered heavy, I don't buy the "don't climb well' myth. Maybe for a little guy but for a clyde to make that claim, I think it's more training than anything. When I'm fit, the wheels are superlight. When I have too much ice cream, they are too heavy for climbing! I've been fit with other wheels and they don't accelerate up the hills any better. If anything, they flex more and fail sooner.

That's just my opinion, but who am I, I don't climb much!

BTW, my climbing bike has a 32 spoke Deep V in the rear and a 32 Mavic CXP33 on the front to save a little weight. When I'm in shape, I dont notice the weight of the rims. Honeslty, I don't notice it when I'm not fit.

cappuccino911

what I meant beanz was not that they couldn't be decent for climbing but that the purpose of deep v's being aero isn't going to help because climbing speeds aren't high enough to give aero benefit, not to mention typical body position on the bike when climbing is going to be as un aerodymanic as you can get.

for lightweight riders, they don't mind putting an extra 100 grams of weight on the rim because the aero advantage at the speeds they ride on the flats more than makes up for it.

i will say that when I switched out my armadillos for any other tire, I definately notice a dramatic improvement. Armadillos are close to 500 grams other tires are as low as 250 so in this case we are talking about taking 250 grams off the perimeter of the wheel, which is quite significant. Typically a climbing rim is going to weigh about 400 grams while a deep v is 500 grams so thats only a 100 gram difference. but ultimately shaving weight from the outer portion of the wheel nets a lot more bang for the buck than shaving the same amount of weight off the frame or the rider.

Mr. Beanz

I knew what you meant, I was just adding to the other than durability (which is my main), they can be good climbers as well due to stiffness.

@cappuccino

I was primarily referring to common factory wheelsets marketed to clydes, which I don't believe put strength as the top priority. If they really wanted strong wheels, they would sell the tried and true setup of a deep rim with least 32 14gauge spokes front and rear. I believe these "clyde" wheels were conceived to be aero wheels, and then later aimed at clydes. "Its aero and strong enough for clydes!"

Hed's Stallion build gives you 20 front 28 rear with 24mm deep rims.
Williams system 30X gives you 24 front 28 rear with 30mm deep rims.
Zipp Max wheels give you 24 front and rear with DEEP 404 or 808 rims.
ROL Race SLR give you 24 front and 28 rear with 30mm deep rims.

As I said before, I acknowledge the tried and true setup of deep rims with 32 or 36 spokes 14gauge, but I feel as though this might be overkill for me as I'm slipping under 200.

Mr Beanz feedback about smushy wheels is something I want more information about.

Would a 36 front/rear aerohead set be weaker than a 28 front/rear deepV set?

The heart of my question can be summed up, if 36 count 14g spoke DeepV wheels are overkill for a 200lb rider that will be racing, where can you make changes for the sake of performance without losing so much strength that problems arise? Less beefy rim or less spokes?

WRT to the people talking about deep-V's;
Yes, a deep-V rim is vertically stronger, *but* it does not address the asymmetric tension on the rear wheel which the Velocity O/C improves.
For example, on my road bike I have a Campy hub with a Velocity Synergy O/C.
According to Rinard's Spocalc.xls, with a normal rim, the NDS tension would have been 44% of the DS tension.
With the Velocity O/C rim, the NDS tension is 66% of DS.
The calculated tension mirrors what I measured on the finished wheel.

FYI I run Velocity O/C's on the rear of both my road bike, and my touring bike, and will be using them on the N + 1 bike I am contemplating.

BTW Big thumbs up on 36H, White hubs, and brass nipples.
