^ I did have a look at BHS hubs when you first mentioned them, but at a glance I thought they were just rebranded Novatecs!

I'm not sure if customs might knock out the benefit of ordering cheaper from the states. Usually I can't be fucked to bother with customs avoidance, but if I order everything from the states, getting someone to bundle it all together and send it as a gift might be v worthwhile.

larger bearings so probably better rolling resistance? (not 100% sure on that though, tester?)

It's complicated, you can only really calculate the theoretical bearing loss once you know the full load/speed/lubrication regime.

Bigger bearings should last longer, being run at a smaller proportion of their maximum load. I wouldn't touch any hub which uses bearings smaller than 10mm ID with a ten foot pole.

I think Hope hubs are nice kit- I own some, and like them.
The CK equivalent of the Hope's I have are £650. That's a months rent. They're so hugely expensive I never, ever considered them as being worth the money.
Are they £400 better than the Hope hubs I have?

Probably not - UK market forces at work there though, a pair of R45/R45Ds is ~$600 USD here.
I guess my point was that CK are a serious engineering concern, and have been for a very long time. No fluff, no hype, they just make great stuff that they can proudly stand behind. I'd say the same about Thomson, Paul, Royce, and a good few others.
With regards to Hope, I assume their hubs are the same awesomeness they've always been (I've had some, loved them). No idea about the other stuff they make.

JOY Industrial Co., Ltd. are a serious engineering concern, and have been for a very long time. No fluff, no hype, they just make great stuff that they can proudly stand behind

Since 1981, just 5 years later than CK.

An engineer is somebody who can make for 10¢ what any fool can make for $1

Followed a guy back last week on a Rouke with Mono RS' they sounded so good.

I'll definitely be looking to build up a set for the De Rosa come summer!

This will look great Mechamorgan, how tall are you?

There may be a slight case of "because show bike"- you saw it at Bespoked a little, and you see it a lot at NAHBs, where the frame builder beats his latest creation with the money stick when it comes to wheels, headset etc.

i.e. ENVE and CK, on ALL OF THE THINGS.

It's a default choice, and even though the parts are probably great they just pass into the "pricey window dressing" arena.

I was genuinely surprised at how nicely the hubs were engineered, I'd probably buy some- at half of what they cost in the UK.

Thanks man! Hopefully I can make it look ever so slightly less grim, and make it ride a heck of a lot better.

I'm 173cm tall - most people my size can ride 53 square frames without too much hassle; I just don't bend well.

obvious next question; pic of you on the bike? Possibly on turbo or something. I thought my body type was weird ..

^ I refuse to pander to #internetbikefit nonsense.

I could lose 200g on the wheels, give or take, with some HongFu crabon crinches. At 40mm deep and 25mm wide, they might even present an aero advantage over the 30s. Was it Small Furry who bought some recently?

He got tubs after melting his clinchers.

pm me then; not trolling; srsly interested

They might, or they might not. There's more to aeros than just depth.

I think they're similarly torroidal, but I'd rather take something that's been in a wind tunnel than something which hasn't.

How much does the flo 30 wheelset build come to above including the cost of building?

sub 1500g - light rims - no torroidal tech but at 32mm im not sure it matters. KT hubs roll fast and last and you get a tried and tested carbon rim manufacturer / warranty.

weight on the rim has to be the key issue vs any minor aero gains from different rim shape. I have found my assaults to be really good over the 2+ years i have had them. taken abuse and all weathers (too lazy to change them).

^^ lots

These are the wheels PX copied and sell for £150. Narrow v profile mean they're quite different to Flos/Zipps etc

I would buy the flo30s and build them with brass nips (if you're using them throughout the year) and Sapim race or CX ray. Most cat4 road racing I've seen don't involve much in the way of long, steep climbs and the air doesn't care how much your wheels weigh.

These should be fast, practical, rebuildable wheels that won't weigh more then other people's deep section clinchers.

The quality of Reynolds versus PX must be a fair way apart (US made vs open mold china). 2011 onward had the heat dissipating CTG track that works pretty well (though not as good as Alu no matter what anyone wants to believe)

I get your comment on shape but with a 30 mm deep rim on an EVO frame surely the rim weight is the key rather than a heavy / reverse engineered version of another companies tech.

Full carbon wheels offer a level of compliance to the ride with tyre size and pressure playing a big role in comfort. Rim width and various white papers all seem to be trying to sell everyone a new set of wheels with minor performance differences. Shallow carbon will not pose any issue in cross winds. Doesn't Paul Lew still stand by V shape vs ball nose rims at most yaw angles (RZRs are still Vs). They revised the rim on the assaults / attacks / strike was to cater to marketing demands for a wider rim bed.

In ideal budget circumstances go for zipp or smart enves as im sure they ride great, but on a budget buy quality / warranty support over back door tech and increased rim weight. Going up hill and accelerating overall wheel weight (specifically rim weight) is king.

I thought those Attack rims were alloy?

Sorry it does mention carbon.

It's the 30mm alloy Attacks which PX based their wheels.

1500g carbon clinchers that aren't even aero... I'm not sure I see the appeal personally.

Full carbon clincher - admittedly not cutting edge tech but tried and tested. Add the rap warranty program and you have crash replacement protection for a reasonable price!

Not aero as defined by Zipp to sell you new wheels. Aero by most peoples standards...

Campy Boras
Fulcrums
Lightweights
Ffwd
Shimano

All still use a very similar profile on their top flight aero wheels.

Full carbon clincher - admittedly not cutting edge tech but tried and tested.

Tried, tested, hotly debated. Read this.

Fair play... There are lots of CC horror stories. I have had good experiences, wouldn't be my choice for alpine descents but that's not the OPs criteria. They are good for south east rolling terrain as you get comfort, aero, reduced rim weight and clincher convenience.
