If you want to achieve a lightweight & STIFF wheelset then you might consider the Giant SLR0 30mm carbon clincher wheelset.... these are 1330grams and STIFFER than waking up with a "weekend woody". +Zero brake rub....I've noticed all ENVE/Zipps suffer from this....Plus durable and very good braking performance in dry and wet.. only just replaced the original bearings after 16,000kms.

These were OEM on all Giant TCR SL0 & SL1 2016+ models...(you could probably find them cheap at a local Giant dealer?) I'm in the process of WW project to drop about 1kg from my current TCR 6.8-> 5.8kgs and it would be difficult to find a stiffer/cheaper set of clincher wheels at that weight......without reverting to LW Meilensteins Clincher/Tubular's.

Giant may not have the sexy name / brand image but performance-wise these are hard to beat. :thumbup:
Wow ill look into those ... didnt know giant made a wheel of that caliber. So your going from 6.8 to 5.8kg - any pics of the build before or after?

Extralite SP-T + SP-X hubs and CX-ray spokes (or equivalent) build a quite stiff wheel.

A friend thats 95kg is now testing new lightweight rims out of China. Tubeless 45mm deep 28mm wide ac3 mimic brake tracks = 400gr a piece.

That equals to a 45mm quite stiff wheelset with great rim braking performance at only 1180gr.

If you're interested look for them on aliexpress. We buy them in china from small suppliers. They're pretty cheap too ~900cny.
Can you provide a link for these. I've been looking for something like this but can't find them.

Thanks

Do you know anything about the manufacturer? They do look interesting.

Only that they look like this after a while. I used to be excited about them but I am no longer. (not my wheels)

Schmolke TL or TLO rims (30 or 45 deep), Carbon Ti hubs, CX-ray spokes and internal nipples.
Bought TLO 45 and same spec as above. Rim tape or strip of own choice.
TL is braided T800 weave, TLO is braided T1000 weave.
Weight is alot less than most options above.

Schmolke have NO restrictions of brake pads, as long as it's for carbon.
You can use Reynolds Blue power for instance. Most are very restricted when it comes to pads.
https://reynoldscycling.com/products/cr ... brake-pads
these wheels look and sound amazing - had a quick look there. Would they be stiffer than the zipp 404 firecrest im running now? As long as the weight is below 1450 ot there abouts then stiffness is more importan to me.
From what i've heard, Zipp aren't stiff wheels?

Mine was 1253 grams. I went for the hubs i was recommended from among others, Hambini.
Also went for CX Ray, not the lightest hubs, because i don't wish to sacrifice stiffness.

In general talking wheel stiffness, how can we know for sure?
I have yet to find a third part that actually come up with data.
As far as i know, RAR doesn't do these test anymore?

My quest was for a wheelset that is light, stiff, durable, great hubs and spokes, great brake track and last, have a maintained ride feel.
Chasing the last grams, well, not anymore. For example, Extralite hubs need more maintenence than many other hubs.
Ceramic bearings, well, i'm done with that...

It rains and snows here now, so i can't do any serious testing.

Carbon is the sensible choice, way more longevity than alloy rims
Carbon has more longevity than alloy? Can you please elaborate?
Sure, personally I have found carbon wheels (particularly tubulars, I only have 1 set of clinchers) to be much more durable than alloy. My lightweight Obermeyers have > 50,000km and are still going strong- an alloy braking surface would have worn out a long time ago. Thinking about it, I have never worn out a carbon rim- I'm sure it's possible especially if riding for long periods of time in bad weather.

Ok, no separate brake track, they just put the pattern on the rim. No good idea. :shock: In this case: What you get is what you pay...

Who'd have thought - cheap chinese products aren't any good. Well I'm shocked.

Thanks, you gotta trust your own experience I suppose. Would it have anything to do with the conditions they are being ridden in? The pads?

I just have my own doubts that carbon brak track is somehow going to last any longer than a quality alloy one. The other thing to factor in is that it's very visible when alloy rims are worn. Not so with Carbon. Maybe they are worn but don't look it because you're getting to lower and lower layers of carbon? I suppose the only way to measure it would be to take very detailed measurements of brake track width over time in an environment with a controlled amount/pressure of braking.

The nice thing is you can afford to swap rims after 2 years. You don't have to try so hard to preserve them.

Enve brake tracks aren't exactly pristine after a few years either.

@paddypurplepuss I just did the same thing as you - coming off a pair of zipp 404s and am tired of getting blown around on descents/climb way too much to hold onto those anymore. Just got a pair of Dt Swiss PRC 1400 spline 35s in the mail today. Will have em up and running Monday and will be putting them to good use all next week!

Paddypurplepuss, those 404's as other posters have mentioned, are notorious for being blown around b/c of the U shaped profile. They designed that profile b/c it is predictable in cross winds. In other words, as angle increases, there is not as big of a snap or yank at the bars when you finally hit the stall point. That being said though, more recent strudies have shown the U-profile has generally more force on the steering axis-- you'll get pushed with far more force, but more predictably.

A few companies such as Bontrager has gone back to the more V-shaped, perhaps even hyrbrid torodial type of shape which has much less force on the steering axis. I'll see if I can dig up the info. The downside is that the stall occurs at a lower angle. But with descending speeds, the winds will be all at very shallow angles to you, close to head on. When you do get a cross wind, it will have less force on the steering axis with the uber-modern profile from Bonty or Reynolds. I have personally noted a dramatic improvement in cross wind steering stability using a Reynolds AR58 vs a 404. I'm your size BTW. Hope this helps.

They must be a fair bit lighter than when they were new 😉

Hey those DTs are gorgeous looking wheels. Did you go for the rim or disc brake version? Can you say why the rim version are heavier than the disc - usually its the other way round right?
