Flo Wheels + rims Flo30 Flo60 Flo90

I have aero wheels and love them and they do work. For training though I prefer "slower" wheels as they make me work a little bit harder. Same goes for training tyres they are always one with higher Crr.

The difference between the flo wheels and OP wheels will be more than 2W it could 15W @30moph at 30kph it would alot less maybe small handful of Watts. However most folk ride low spoke count wheels e.g. campag Zonda's and the difference between these and the flo's maybe in the order of <5W @30mph. don't get me wrong in a TT situation even if all you can do is a 19mph average aero wheels do make some difference it is real. I don't think the difference is dream like though you still have to work.

Miche Primato do fixed hubs in 28H. I have some on the way from Miche. BLB also sell there own hubs in 28H. Phil Wood and Paul do 28H hubs. Plenty of choice really.

That's basically what I said. The drag power at 30km/h is only about 22% of that at the usual testing speed of 50km/h

I'm thinking of getting the road wheelset and an extra 28h rim to build up for track/fixed use. Just gotta find a 28h track hub…any suggestions?

Get an extra 24H rim, then you can use a Novatec hub, which is easily available in 24H

The problem with Watts at a certain speed figures is that they seem impressive, but unreality they are not.
Firstly, I cannot pedal at 50 Kmh, which already puts those numbers beyond my reach. I can pedal at 40 Kmh for short distances, maybe up to 5 Km on a good day and I can definitely pedal at 30 Kmh almost indefinitively given no wind and a flat road in good conditions. So those 15 Watts are more like 3 Watts in my real world. Ok, I've got 3 watts for free, which is somewhere between 1-2 % of the power I require to keep that speed... or let's put it in another way, how much faster can I go with 3 extra Watt?

Using one of those power calculators I get something in the range of 0.1 to 0.2 Kmh faster. So in an hour I can go roughly 150 metres further. A quantity that would be already meaningless in an hour record attempt effort, probably superseded by a long mile by barometric air pressure on the day... how meaningful could it be in a 10 miles time trial context? Not very meaningful either... probably looking at finishing 70 metres ahead, which is what? 7 seconds or so?

Numbers numbers... :-/

Shallow alu rim in 'not quite the aero breakthrough we thought' shocker

That was pretty much the exhaustive list of hub options I'd come across…but:
Miche - cheese
BLB - A.BLB B. Low flange
Paul - Weird chainline
Phil - $$$

Any other options?

But what you're saying is I should scrap this idea and come visit Glemhole for a pair of hand built open pros?

I've exchanged a few emails with Jon (Co-founder) and he recommended 28h, even then was slightly reluctant to give it the thumbs up until I'd said it would be built 3x but someone who knows what they're doing. Reckon 24h would be fine and he's just being over cautious?

Sale opens (and probably closes again) in the morning…I'd better sleep on it

Are you heavier than me? I'd happily ride track with 24H on the back with any rim that's sold in 24H. The Flo30 isn't so far off the Mavic Ellipse rim in terms of weight and depth, and Ellipses worked for me with only 20 spokes. Track rear wheels need fewer spokes than road wheels to achieve a given axial stiffness due to the lack of dish.

That depends on how heavy you are...I'm 73kg. I've got a friend who's been beating a set of Ellipses on the road for years and reckons they're bombproof. Also the American classic track wheel set is 24h rear and uses a lighter rim.

I believe that MDCC_Tester comes into the "prosperous" weight classification, so you'll be fine.

You have a set right? How do you rate them?

Great wheels, love mine - I don't think there's anything else in the same price bracket that is comparable.

Have you got a link for a supplier of 24h novatecs? or any others for that matter. There seems to be even less options for a 24h track rear

Cheers for the feedback, those were my thoughts on looking at them and reading other testimonials

Try Novatec... BDOPcycling have them in all counts.
Not sure about your statements though... Miche cheese? Why?
BLB low flange, so what? The contribution to stiffness of a high flange hub is close to zero. Roughly speaking, for every millimeter of flange width, you need over 5 mm of flange hight to achieve the same bracing angle... besides, with a 30 mm rim on a track hub you've got all the stiffness you might ever need.

basically you are overcomplicating a wheel which is really that simple

Cheers for the bdop link, had been googling and searching ebay and found no simple options.

Re: miche - I've heard enough from both friends and forums to suggest that the quality isn't what it could be and because of that would rather not use them if there's another option.

Low flange - Because I was advised by the guy who designed the rim to use a high flange hub, I'm sure he's erring on the side of caution when giving advice but still it's a valid opinion to consider.

I have never used Miche track hubs, but I have built several other Miche hubs... they are generally better than equally priced competitors... the internet is often full of twxts with zero knowledge and lots of opinions. I would be surprised if Miche track hubs were really bad... but hey oh... what do I know? I don't want to add my voice to the plethora of nonsense.

High flange will make it only very marginally stiffer, OK if you find them, otherwise it's not an issue.

The Novatec are as good as any out there... in fairness there is very little that can go wrong in a track hub... typically headaches derive from having a freehub mechanism

So would a Flo30 be a good rim to build up for track or is there a more preferred rim in the same price range?

Looking at an Ellipse wheelset for the spring, but these look promising.

I don't see why not... however, if you are doing sprint I would probably look at a rim lighter than the 560 grams for this... acceleration is a function of the weight you have to shift and might be more important than the marginal aerodynamic advantage. Vice versa, for pursuit aero will be more important than rim weight and the FLO might be a good bet. The Ellipse seem horrendously expensive for what they are. You should be able to get a better set built for you for a lot less than the 350 they retail for

the internet is often full of twxts with zero knowledge and lots of opinions

Well yeah, just like the real world then, but you weigh them up against their credibility, the opinions of others and your own experience and try to make decisions based on the evidence as you perceive it.

Like you say a track hub is simple, and I'm sure a Miche one would be up to the job but if I can get one that doesn't have that negative connotation in my head then I will.

…..Anyway, I'll see if I can get in on this order and if/when I get my wheels/rim I'll offer up my opinions here

If you're planning to use 23c tyres, these might be similar at much cheaper cost.

The Kinlin are great rims for the money... however, for a track bike you carry around a pointless and heavy brake track... why not getting a disc specific rim that has no brake track? Something like Velocity Aileron or Pacenti SL 25? They are more expensive, but they have bigger volume at less weight and they come in 24/28/32 H.

Have you got a link for a supplier of 24h novatecs?

24H are in stock at http://www.planetx.co.uk/i/q/HUOOLF/on-one-large-flangetrack-hub

Dunno how I missed that, cheers. That's the easiest, cheapest solution by far

What do flo rims come to delivered to the uk?

about £330 off of me, laced to royce hubs if you want some right now ;), though Howard has first refusal once I get round to taking photos.

Otherwise about £80 each.
It cost me about £250 to have two new rims shipped over and laced to my hubs, including build cost and spokes
