    I got a pair of Superteam all carbons like a year ago for $700 1400grams a pair 50mm deep. Love them. You should set them up tubeless or with some AliExpress TPU tubes. Significant weight savings and much better rolling resistance than the old rubber tubes.

    They look great! I have a set of carbon fiber wheels on my rim brake road bike with the same etched rims from Light Bicycle and the special compound pads. They stop very well. The pad compound is pretty soft so you will go through them much quicker than standard pads, but it's well worth the performance upgrade. Enjoy the new wheels!

    Put a set of elite wheels on my bike back in August. Biggest difference for me is how nice they roll. They replaced the original wheels that came on my 2011 Specialized Secteur. Put new tubes and tires on at the same time and trimmed 2.7 pounds off the bike weight. Braking performance is definitely a place they lack in comparison to the alloys they replaced.

    Fascinating to see so many comments bemoaning Chinese wheels. But they do not drill into the carbon spec versus ‘western’ brands when they do, nor seem to realise that the ‘western’ brands are primarily middle men with the Chinese (Xiamen, I believe) factories that make ‘their’ wheels. Nobody in the mass market is moulding carbon in Europe or North America.
    My own carbon wheels are ‘western’ branded (bought in super discounted sales last year) but my next set will be direct from China unless I see a super special discount again! So this video is useful. Thanks.
    I also notice that Vel (the Sigma in house brand) seem to be discontinuing their wheels, given how few are now available on their website. My guess is that they have chosen not to try to compete with the direct from China market given that they are a ‘value’ brand. Of course, there will always be someone happy to pay £2k+ for a ‘high end’ wheel set just as some people are happy to pay £10+ for a ‘high end’ bike!

    To increase the brake perf, I advice you to set up a Darkpads carbon wheel brakepad. They are designed to cool down faster the rim than a normal carbon rim brake pad, and have better brake performance. It's a French brand that makes Makadamm Wheel set as well. Should have a look😊 enjoy the rides ! Merry Christmas to your family and you! 🎉

    Those old wheels were budget Shimanos that were expected to be ditched by a discerning owner straight after purchase and kept for winter use and abuse.
    Nice free upgrade but properly built Mavic or DT Swiss rims would give a perfectly good improvement. Obviously the carbon Tech and tubeless tyres are now improved and optimised after a few years so they are a sound investment even if the Aero aspect is irrelevant for most cruising riders.

      @@Quizmate1 Cheap carbon wheels often tell a lot about the rider, and how unmechanically savvy they really are. A good set of CF wheels with reliable hubs may be a small upgrade, but most buyers of Chinese junk do it to look fast, and do not understanding the risks and reliability issues they'll face. Part of the blame though, goes to unscrupulous social media influencers that do paid reviews.
      On the other hand, good quality aluminum wheels, especially, on rim brake bikes, are the smart choice for 99% of riders. For example, DT SWISS makes some great AL wheels and have bullet proof hubs, that even if they ever need service or repair, can be taken care of by any LBS. The wheels this reviewer put on his bike aren't worth the cost...and they're free 🤣

    replacing a WHOLE WHEEL. That is just plain ridiculous and any rim brake enjoyer would do well to avoid that,
    For disc brakes a wheel upgrade is a good idea (tho better tires is always more economical).

    Worth what? They certainly helped me to winning our local season TT series in the road bike category. I had them on an upgraded Tarmac S-Works SL4. Rim brake. lol

    Warning - many of these comments are seeded by sponsor. Superteam is a dodgy Chinese seller of cheap quality wheels. Buyer beware!!!

      @@danisagala1908 I think you know the truth, but you want to believe you got a great deal and want to believe the fake reviews. Confirmation bias will prevent you from accepting any evidence. Good luck....youll need it

      @@danisagala1908 I could point you to the emergency ward where you'll find victems, of these crap wheels, but just look at what you get and the price. If its too good to be true, it probably is.

      Just ask yourself, would this influencer have chosen these wheels unless they were free and he was paid to give a glowing review. He seems like a nice guy, so it's disabled he's selling out and offering advice that may be hazardous or at the very least, introduce a ton of headaches.
