more spokes - more material moving through the air - more drag (air resistance)

Exactly. A huge part of the benefit of aero wheels comes from their having fewer and shorter spokes than "classical" wheels. Flattened spokes are also a huge benefit, but you can have those on any wheel if you're prepared to pay.

What is spoke drag?
More spokes = more time for them to hit the right tension and get going?
Bro do you even aero?
-
• #2705
Yeah man. Aero as fuck. I've got some 50mm Planet X wheels which I've never glued any tubs to. But I'm sure they're pretty aero ;)

Pretty boring: Need some lightish wheels. Clinchers. £300 or so.
Black/SRAM 10 speed.suggest plz.

Why do you think you need them to be "lightish"?
-
• #2708
Paid performance gain rather than trained. Shameless.
-
• #2709
Tester will now probably be writing about the many ways you could gain the performance without going light, centring around aerodynamics

My body is ready (but not aero).

Zipp did a little research in 2004 on the effect of spoke count in a wind tunnel at various angles using a 404 rim and between 16 and 28 bladed spokes. The difference at the time was possibly between 1-5 watts and that could have been noise in the measurements .. They also ran a test on a traditional box section GL330 rim and found that 18 to 20 bladed spokes gave an improvement of 20 watts over 32 round spokes.

Seems fair in a country of flat marsh and meadows.

Get something you can build new rims into. And get the miles in.

do you even previous page?
If weight is to money is what you are after then i'd recommend these:
Rear hub: http://www.bikehubstore.com/SL210-p/sl210.htm 210grams
Front hub: http://www.bikehubstore.com/product-p/ulf66.htm 66grams
Wide Rims* x2: http://www.bikehubstore.com/C472w-p/c472w.htm 980 grams
Spokes: http://www.bikehubstore.com/product-p/zscxr.htm 252 grams for a 28h front and rearTotal of 1448grams and $408/£245 plus LBS wheel build £50
*for comfort mainly
If you swap comfort for even lighter wheelset then you can save 214 grams with these non wide rims (also cheaper): http://www.bikehubstore.com/Kinlin-XR200-Rim-p/xr200.htm
I have a BHS hub on Kinlin XR200 wheelset on my road bike and its great. These were built by Fitzrovia Cycles.

RS11s are fine, but with the low spoke count it's probably even more worthwhile to spend the extra for deeper rims and butted spokes, http://www.ribblecycles.co.uk/sp/road-track-bike/wheels-factory-built-wheels-factory-road-tri-shimano-rs31-clincher-wheels-pair/shimwhfr379
Killed my font hub of the RS80's with a duff spoke. Was going to ask for either a 16 h front hub recommendation, or for a ~30mm 20 h rim recommendation, but I'm guessing I'm not going to do much better than those (with the 10% off) until it gets a lot more spendy? (keeping in mind I'll need spokes as well for either of those two options)
-

If you want 20 J-bend spokes on a 30mm rim, there's always the R501-C30
-
• #2718
The rim option was to build up onto an old DT Swiss hub. Is there going to be a noticeable improvement between 16 db spokes on the RS31 and 20 standard spokes of the RS501?
(rolling on a road bike at ~20mph) -
• #2719
You won't notice it, you may not even be able to measure it since the R501-C30 has bladed spokes the same as RS31.
If you have a 20h hub, Flo30 is likely to be the best metal rim you can lace to it if you're after going fast, Sapim CX-Ray spokes obvs. :-)
-
• #2720
i feel a flo30 groupbuy coming on?
-
• #2721
Hmmm. Sounds like R501-C30s for general use then, and then a (pair?) of Flo30s at some point
If you have a 20h hub, Flo30 is likely to be the best metal rim you can lace to it if you're after going fast, Sapim CX-Ray spokes obvs. :-)
All of this adds up to a 1,585g wheel that cuts through the wind and rides incredibly well.
I'm hoping they mean a wheel*set *at 1,585g!

MDCC - those Flo wheels, are they all alu brake tracks with fairings?
Answer: they are.
-
• #2723
Flo 30 are all alu
-
• #2724
They do look good I am tempted.
-
• #2725
could be keen as well
does anyone know the erd and weight of the flo30 rims?
