I know the new MY2015 Bora Ultra Clincher 35x24.2mm version is so new that it is likely untested but based on what we know …

NEW FULL-CARBON RIM, 24.2 MM WIDE
EXCLUSIVE G3™ SPOKE PATTERN
CARBON FIBRE HUB
OVERSIZED FLANGE

Should I expect them to be stiffer or less stiff than ENVE 3.4 SES Clinchers + Chris King R45 20/24H + Saprim CXRay spokes?

The huge voids between the spoke groups on the rear Campagnolo wheels makes me question the stiffness but clearly they believe in it.

I would also consider moving up to the Bora Ultra 50x24.2mm if they are much stiffer than these others.

stiffer in what way? laterally? radially?

heres an article for ya:
http://www.slowtwitch.com/Tech/Debunkin ... _3449.html

If you've ever ridden campy wheels before you'll know that campy G3 lacing pattern works. Campy wheels ( especailly the bora) are some of the nicest riding wheels I have ridden and raced on.
Have never heard anyone complain about boras being 'not stiff enough'

how stiff you will find the custom build will also depend heavily on what lacing patterns and what hubs you use.

If the CK/Enve combo isn't stiff enough, use DT Aero Comp spokes instead.

Otherwise the answer won't be known until they have been tested side by side which I doubt will happen anytime soon.

The Campagnolo spoke patten works best with carbon rims. Carbon rims are much stiffer than their alloy counterpart unless the carbon rim is some gram counting project which Campagnolo isn't known for.

What did you choose? Has anyone ridden the Bora Clinchers yet?

I already have the ENVE 3.4 set - will only buy the Bora set if I can be certain they are stiffer.

I very much doubt they will be dramatically stiffer than what you have.

If you really want a very stiff wheel then look elsewhere. Bora have in the past tested as stiff-ish, but there is nothing in the construction of the new iteration to suggest a dramatic increase. Perhaps a bit from the wider rim?

Go for CCUs or Lightweights if you want something noticeably stiffer than what you have

Dreaming about an asymetric Bora 35 rim à la Hyperon, Mavic CCU or Shimano C24, rear wheels that are notoriously really stiff and responsive

Well, they would probably build one if added stiffness was really necessary

I run Bora 35's all the time and had the opportunity to ride the ENVE 3.4 with CK hubs today. I was shocked at how much flex the back wheel was displaying on the ENVE's. A good 3mm each way to the point where I had to loosen the brakes off to stop it. They did sound nice though.

Campag all the way as they are infinitely stiffer.

^ I use Enve 3.4 with an extralite hyperreal hub (2x DS/radial NDS)... I'm also 180+ pounds.. if the enves flexed that much I'd be in trouble.. I run my brakes closer then 3mm

As do I, my brakes are normally run quite close but don't rub on my Campag wheels. May have to reconsider my options now as I was going to go for ENVE on Tune hubs!

The stiffness of any Enve build is going to be limited by the hubs that are available for the build, rather than the rim. One of the advantages of a system-built wheel like the Bora is that you get rid of this limitation - when you've got a rim that's made to work with one hub, you can push out the bracing angles considerably further than you otherwise, which yields much improved stiffness. I'd expect that in the absence of any other factors, that aspect would at least be one point in favor of the Boras

That makes sense. What hubs can you recommend to pair up with some ENVE rims?
