Looking at building a tubeless set of wheels in the near future, preferably straight pull for something different.
I'll be using Stan's NoTubes ZTR Alpha 340 rims with an 18 or 20H front and 24H rear.
Also, how much does the weight of the hub affect the wheel, because it is in the center so I'm guessing a slightly heavier hub with better bearings would perform better than a lighter hub with 'lesser' bearings? Currently using a set of UniQ hubs which cost around $150 or so and they are excellent for the price. They feel a lot better than my old pre-build carbon wheels from China which had some Novatec hubs (and the UniQ hubs are about 70 grams lighter or so. I have some Circus Monkey HRW2 hubs that I am going to use with some new carbon rims which are light and feel really nice even in my hands (bought 'spare' bearings for the front).

Another question, why are there so many hubs for disk brakes?

I found some hubs on a site called "ZakazExpert" (sorted in lightest to heaviest);
258 grams $275 = http://en.zakazexpert.com/index.php/tao ... 7008402321 (description was VERY unclear...)
270 grams $280 = http://en.zakazexpert.com/index.php/tao ... 6155185487 (not straight pull but still seem nice)
284 grams $246 = http://en.zakazexpert.com/index.php/tao ... 9724788091
287 grams $180 = http://en.zakazexpert.com/index.php/tao ... 6990872541
293 grams $240 = http://en.zakazexpert.com/index.php/tao ... 8357021551
303 grams $286 = http://en.zakazexpert.com/index.php/tao ... 9314661279 (favorite looking)

Any other recommendations are very welcome!

Bikehubstore is well discussed on this forum. I have a set laced to stans a340's. I believe the hubs are made by Bitex. Alternatively you could buy some ED hubs form farsports (China) - these are also made by bitex but slightly lighter.

Bikehubstore hubs if you want cheap lightweight hubs.

Tune hubs if you want good quality lightweight hubs.

Extralight hubs if you want some of the lightest on the market....

But it´s cheaper so shave of grams other places on your bike. And it makes no difference since the hubs are in the center of the wheel.

Or Farsports for light cheap hubs. If you want the lightest though, Dash Cycles

The BHS straight pull hubs are Powerway R36 hubs and cost only $150 from eBay: http://www.ebay.com.au/itm/powerway-R36 ... 611&_uhb=1

My budget is about $300 for both hubs.

I can get the Hope Mono RS 32h rear hub for $210 delivered. I am planning on possibly doing a triplet lacing to a 24h rear rim. Then I might use a cheaper front hub, such as this 'generic' Taiwanese hub: http://www.ebay.com.au/itm/331065684909 ... 1438.l2649

Is it true that the front hub doesn't really matter much?

Could you please elaborate on triplet lacing.

That looks the same as a BHS SuperLight 79 Front which should be a good hub with bigger bearings than the cheap 60g hubs. BHS also has similar hubs like the SLF85W that have wider flange spacing which helps make a stiffer (though less aero) wheel.

This is what I am referring to when I say triplet lacing: Image

So missing every 2nd hole on the NDS? What advantage does that have?

Equal tension on both sides of the wheel, plus it looks great. It s a 2:1 lacing pattern, so 16 drive and 8 not. I think it makes it stiffer too.

I´m pretty sure that you never get a stiffer wheel by putting less spokes in it.

Less spokes is only about weight savings, aero and looks.

It depends on how you look at it. This wheel has the same amount of spokes, just half of the spokes of the 'strong side' (non drive side) are moved to the 'weak side' (drive side).

Fewer spokes makes fewer spokes to hold the tension, which makes a less durable wheel.

The more spokes you have, the stiffer the wheel will get without breaking, when you tighten the spokes.

I agree with you, but a 24 hole rim built with triplet lacing is probably stronger than a 24 hole rime laced traditionally. A 32 hole rim on the same hub will make a stronger wheel.
