UPDATE:

Spoke too soon. After my ride yesterday evening, I did experience some minor pinging from the front wheel when out-of-saddle. This can be solved by tightening the preload just a bit on the front hub. Apparently, this has been very common for these wheels so far.

The only other negative I've experienced so far is that these catch a little bit more crosswind than my other wheels. Nothing major, but it's noticeable.

Finally, solved my rear rotor contamination issue by soaking in dishwashing liquid, scrubbing, drying, then wiping down with alchol wipes. Fixed entirely, and now the braking is silent and phenomenal.

So, as it turns out, just about everyone has had spoke tension issues on the front wheel only with these wheels. The spoke tension on delivery for the non-disc side was 68-75. Recommended is 90. The spoke tension on the disc side was 110-114. They recommend 145. Retensioning makes the pings disappear. Dissappointing from Extralite, for sure, but at least it's solvable.

On another note, these wheels continue to blow me away. It's the single biggest upgrade I've ever experienced in my 20 years on the bike.

I will check the spoke tension on mine this weekend. Have now managed to get my Cervelo R5 Disc down to 6.3kg!

What other mods did you make to get it below 14lbs?

Sometimes inflating a tight fitting tyre on a wheel provides better stress-relieving than any amount of manhandling. I have a set of Alpha 340s that I had to retension with a tyre inflated!!!

Anybody with some more feedback? How flexy are they compared to roval clx 32. I am a 78kg rider and strongly consider this wheelset.

Just ordered some of these myself last week - already shipped and on their way to Western Canada. So probably a few weeks out still.

I also ordered some Schmolke TLO 45 Clincher with Tune Prince/Princess Skyline Centrelock hubs to try out against the Extralite eventually.

Running 2019 Cervelo R5 DA Di2 with the DT Dwiss Spline 1450 Disc wheels currently.

Size 48cm frame, with all stock parts comes in at 7.27kg / 16.03lbs

I calculate the Extralite CyberDisc 38c will save me 400g (1480g DT Swiss to 1080g Extralite).

Based on the terrain and twisty descents I perform on I'll be using Shimano RT86 rotors which won't win any weight weenie awards.

Still, it's the going up part that I ordered these for and I'm excited about :)

Yeah - I'm not familiar with these off-set type rims. Will be veru interesting to see how they handle.

However - the main reason for these is I will be Everesting a local mountain in a couple months - So ~9,000m climbing at a fairly easy speed at avg 6% climb - aero not needed since my only time to eat/drink will be on descent anyways so - even if it's a touch slower going down I'm good with that!

I can't see it, but can anyone confirm if there is a weight limit?
