You should 3D print a valve port cover out of TPU.
Black gaffe on mine after I ran out of the lite weight stickers
It's great to see options to big expensive brands.
Great to hear another good 9velo review as my wheels, bought with your code, just arrived! :D
Which ones did you get? I have the older and cheaper, previous gen RV55 set. Wanted to see what carbon wheels and rim depths was all about and didnt want to put big money down on a set twice as expensive.
Ridden mine for around a year then had my LBS do an inspection on top of a bike service. The wheels were perfectly fine although they couldnt comment on the quality of bearings used. Other then that, they spin true despite all the potholes ive crashed through.
@@Rose.Of.Hizaki the recently launched LV45 2.0. They look good and weight nothing, that's about all I can tell so far :D
@@MrMattie725 I just had the exact same ones arrive. Can confirm they're ridiculously light, look quite good and seem well made. Wish they'd do a higher tier finish (other brands have super luxury looking raw carbon/glossy finishes) but they seem good to me so far :)
How do you know brake rub is not due to flex from being such a thin disc with no spokes?
Opinion on this theoretical combo?
Front 50-55 mm deep, ~21 mm internal ~28 mm external at the rim. Bulging profile like scope artech, clx2, meaning that with the right tire, the cross section of the tire and rim looks like an ellipse. Ideally run with 25~26mm tire.
Rear 60-70 mm deep, ~24 mm internal, 33-35 mm external. Same general profile.
Good old Monty! Wouldn’t want to get caught out in a beastly storm
Super interested if you end up printing or designing a valve cover for these.
The semi lenticular shape being better makes sense, we dont want air to "crash" into the round hub/freehub. a smooth transition creates less turbulence i.e. form drag. the drive side has the cassette... unles you are running a track bike, either way in needs some space for that and a gap for air to funnel helps re-attach the air to the wheel (i.e. less turbulent dissipation)
as for the tires.. i understand the choice for comfort for dialing in tt position, though for TT speed i'd switch and go for a 100% match (or smaller tire) between rimbrake surface and tire.. if the tire is wider then the rim it will have stall angle at less yaw angle.. the air will have difficulty to re-attach to the disc wheel undermining it's entire benefit
Can anyone explain what the point of a hollow wheel (removing the foam core) is? Losing all that structural reinforcement you either end up with a flexy wheel like this one, or else heavier with all the extra carbon, or compromise the shape.
And not having a velcro cover is giving 1997 zipp vibes.
Gotta say this video really isnt up to your usual quality, could have waited until you got aero data?
Oh yeah, from the wind tunnel in his basement. 😅
@@petersouthernboy6327 watch his old wheel videos, it's aero sensor testing /chung method
@jonathanz9889 silence vermin
Im building the whole database again as im now on a new sensor. One wheel on its own with no comparison is useless, as in absolute terms im not sure how accurate the new sensor is!
@@jonathanz9889 unfortunately that whole data base is on the road bike with disc brakes too. The only other TT wheelset i have now is 50mm rim brake clinchers so id be hoping the disc wheel was fastest!
What bearings and freehub system are used?
It should be a taiwanese made DT knock off
any chnace you can review the nine velo mt30 mtb wheelset before I pull the triggar on some?
I already have!!!
@@PeakTorqueI race and im wondering what would you say the best value Chinese wheelset is? Im leaning towards the magene ultra 508. I know you are a busy man so I really appreciate if you can help me. Really love you’re content as well
Can we see some 360 drop spins to flat to test strength
oooh ... you got a new Trinity? 😍
proper dinner plates
That sou d check was bass.
It would be interesting to have the resources to research on actual disc wheel models... that research shows flat disc produce more drag. however, zipp came a few days ago with a new disc and just made it wider as parcours did a while ago and both still flat on both sides.
I have this same diac from aliexepress. If you sont want logos then you can save a few hundred bucks additional.
Also i had a textured brake surface applied and for a rim brake, its not too bad. Its not fisc brake by any means but with campy red pads and the groves surface its respectable.
personally speaking, I'd just run 28R/25F tire combo on that bike (especially considering it's a TT bike). I wouldn't dik around with clearances that are THAT tight; any tire rub and you're past the point of diminishing returns.
that being said, I totally get why you'd want to go fatter, I run 30's on my road bike and don't see a single reason to go narrower.
btw, that is a nice wheel, especially for that very fair price.
Only had the 30mm back tyre for comfort/longer training rides on the bike. Best way to hone the position. That said, there would be no penalty running the 30 vs a 28 rear in terms of Crr.
Narrow is aero
That horrendous noise at the end :( . Thought I was on a GCN video.
Noisy freewheels are wasting energy downhills 😂
Shave those brakes!
Funnily enough i have a custom oem version of this, picked it up for ~600USD in China. Lemme know if you guys have any questions
Edit: actually two, one with dt240exp but a heavier carbon layup and one stock at 980g
Where did u get it?
@@normen416 Chinese ebay, not really accessible to foreigners but you can talk directly to the factory people
How do you mean custom? Please share the taobao link. When you say oem, this one is made by a very big factory if you know what i mean… so its as oem as it gets
@@PeakTorque it's available via xianyu which is Chinese ebay only, and I don't believe foreigners can use it since it requires a Chinese number
You can talk directly to factory guys to ask for custom paint/carbon texture/hubs configs
Isn't most 9velo stuff just farsports? Their rim profile drawings are completely identical in style to farsports.
I cannot confirm or deny…
@@PeakTorque ninevelo exposed 🤨😏
Rim brakes "an absolute shit"
I want new wheels. All of a sudden ENVE are the affordable high end option.
Since when?
@@sempi8159 since I’ve been looking I guess. Their competitors have higher prices. I didn’t look at Zipp. Reserve and HED and some custom options are $$$ while the SES price hasn’t moved in a few years.
Well, they're cheaper than Lightweights😂
check out Parcours wheels (based in England).
@@veganpottertheveganlightweights were obsolete years ago.
