Light Bicycle wheel rims?

Sorry, this should be WR40!

What are everyone's thoughts on manipulating hubs / spokes to sort of optimise weight to stiffness and strength.

That is to say, can you really beat 240 EXP + CX-Ray by much? 180's are lighter but a LOT more expensive. Brass nipples are a little heavier but increase reliability. Alpina Hyperlights are a bit lighter again. Alpina do a Superlight a little heavier, worth it for the Rear Drive Side? What about Carbon-Ti Hubs - 180 weight but 240 price. Is there much of a reliability cost?

Internal nipples are a lot more aero, but the problem is I don't think you can re-tension them once the tyre is installed - which means your wheel will always be very slightly under-tensioned.

This is for two wheelsets - a set of Turbo 50s for gravel racing and a set of XC930's for Marathon racing in all weathers. I'm not super keen on carbon spokes becasue of impact resistance and the requirement to use a proprietary hub that I can't just get parts from at a local shop / press my own NTN bearings into etc etc.

I was just scratching my had wondering if that's what you meant.

I've been running these as gravel wheels and recently switched them to road duty while I figure out what I want to do bike wise. I'm running them on Giant Revolt, with GP5K S TRs at 28mm. With the 25mm IW, the 28mm tyre expands to hair over 30mm.

Technically I shouldn't be running 28mm, as the ETRTO standard states +4mm, but I haven't had any issues and I know a few other posters on here have had similar results.

I think they have a nice, semi-symmetrical oval cross section with the 28mm tyre - the rim edge is blunt and curves in similar-ish radius and shape to the tyre, which is also blunt.

I'm running them with DT 240s and C-Xray spokes at an overall weight of 1412g.

They feel good and I have had no issues with their performance, set some PBs on strava etc. Being shallow there is no issue with wind.

I was actually all set to buy some Newmen Vonoas, and I likely still will, but these have been better than I thought. Biggest difference for me was comfort and therefore I imagine speed; I was rolling on rim brake 25mm GP5K at 26mm WAM. 30mm WAM gives a lot more cushioning.

Overall a very versatile wheel that I have hammered on gravel and found pretty decent on the road.

Thanks for your detailed reply. My thinking is that I'd use these for longer days out and where comfort is paramount. I've got a set of lightweight Alpinist wheels that came with the bike which are more than adequate but I'm definitely after something a little more versatile. Managed to get a build with DT240s/ CX Ray's and with a 15% black Friday offer brought them to a pretty competetive price.

Any advice/experience from people who've used the AR40 as a road bike option would be greatly appreciated!

Sorry, this should be WR40!

Lots of people using the WR series for the road. I have WR38 on my winter bike and WR50 on my fast bike. I can't fault them.
And I have a set of WR40 on order for my travel bike. I have to admit to being a bit excited about getting some wavy rims despite initially struggling with the aesthetic. The X-Flow is looking better all the time. (Might have something to do with the introduction of the Turbo series which is too weird for my conservative tastes.)

I agree on both counts. The turbo is pretty crazy but will end up looking normal in a year or two, but makes the x-flow more attractive right now. I also think their version of the waves being on the side profile instead of the common trailing edge seen on many brands looks more refined.

I did consider the turbos when I was looking at going with the Chris King hub option, simply because it was the only way to get the weight down for what I was after. After reading quite a bit more about CK hubs, I decided dt swiss is probably a better option anyway (for my very rudimentary maintenance skills!) and yeah, the turbos are a bit too out there for my tastes at the moment. They'll probably be everywhere in a year or too though!

Lightweight pace hub, thoughts?

Eh, theres lighter for less

[alanyu]

I have asked them about bearings in the new hub, and they are:
front: 15267 + 6802
rear: 15267*2 (body) + 6802*2 (freehub)

I don't like small bearings

[biscottigelato]

Looking at the Pace-Hub too. They can bring a pair of AR25 down below 900g! Tempting. But not quite enough given the lack of Black Friday sales~

[MichaelK]

Such as? Also how would the quality compare?

[toxin]

H-works has a bunch, reputable quality, goldix has a few, unknown quality

I run a set of 28h wr40s spoked to an Erase hubset for winter road duty. These pair really well with vittoria corsa controls in 28mm (31WAM). (Nearly as good as my bontrager RSL wheels).

So reading that, seems like they really just added DT' internals.
