Ok, here is a very brief impression of the 45mm U rims/wheels from Light Bicycle. The build was the 45mm U rims in matte UD finish, bitex hubs (ED), and pillar spokes. 1389 gram.

To qualify, I am a recreational rider, not a racer. Just someone who rides with a club on Sundays, and catch a ride or two during the week, if life doesn't throw a wrench into things. I am a relatively heavy rider at 200lbs/93kg. I live in a flat area, without high speed descends or massive braking requirements.

Pros-
1. These babies are light. For a U shaped 45mm wheels at 1390g, what more can you ask for. They are probably 100g less than the Zipp 303, the rims they are modeled after. I venture to say that a lot of it has to do with the hubs. The hubs, by the way, are smooth. I really enjoy them.
2. Wheels are stiff. Even for my big behind, these babies do not flex as much as the current carbon wheels that I have, which are Syncros RR1.0, rebranded Reynolds 46 rims with the swirl lip thingy with the similar hubs as DT Swiss DiCut RRC46. Those wheels flexed more on out of saddle. From the initial riding of the Light Bicycle wheels, not much flex that I can tell.
3. These wheels soak up the bumps compared to the Syncros/Reynolds. However, I have to qualify this, I the Syncros has Conti Force/Attach combo with Vittoria latex tubes, while the 45mm U has Vittoria Open Corsa 23F/25R on Verderstein latex. It could be the tire combination, but i also ran the same Vittoria Open Corsa setup once before and never felt this "plush".
4. These are nice looking wheels. Quality and finish is surprisingly good for something that cost $560. I can't fault it for anything quality related so far, but it has only been a week.

Cons -

1. Braking (big concern). These wheels do not have the basalt treatment that I see from the Farsport wheels. The same UD carbon weave that was on the rest of the rim is on the brake tract. I don't feel that these wheels have the same bite as my current Syncros/Reynolds, which has some type of treatment 3k weave from the rest of the UD carbon rim. I am using reynolds blue pads, which by all accounts, are good pads, but they just don't have that grab. In the rain, who knows. Like I said, I don't live in a hilly high speed decent area, so not as critical to me, but it is something worth thinking about. Maybe some other owners can chime in.
2. Wheels came just with the wheelset. I see that Farsport gives a nice set of ti skewers and blue brake pads. Also, Farsport is 60 more for comparable 50mm U rim, so who knows. I would like to get something. Light Bicycle did send a nice message in a nice card though.

Overall, there are some good points, weight, price, and ride quality, and some points that may be concern. Braking for one. I was not expecting much from this set of wheels. For the price, it is very good. But if you are concerned about braking, and want the best brake tract treatment, I would consider something else with the basalt treatment for better bite.

Do you think they're faster than other wheels you've used, Syncros or others? If so, in what way: accelerating out of corners, going up hills, holding speed in the flat etc?

I've been using Vittoria, Michelin and Vredestein latex tubes and the Vittoria are noticeably more butyl like than the other two. The Vreds provide a better ride, along with the Michelins, but are the faster of the two. The Vittorias are disappointing, no different than 70 gram butyls. In fact the real ultra light butyls like Conti Supersonic and discontinued Forte Lunar Lites, the 50 gram tubes, I find preferable to the Vittorias and very close to the other two. Not to mention your tire differences, open tubulars compared to garden hose. I think you're right to reserve final judgement on the wheels themselves being that much more compliant 'til you do some more mix and matching.

Does anyone know what gauge/length of nipples are used on the Dengfu carbon wheels? I've got the 40mm wide profile clinchers and have managed to round a couple of nipples with my fists of ham, so need to get some replacements. I believe they use CN 424 aero spokes, so 2mm gauge? What about length?

I think that for carbon you need to use 14mm instead of 12mm. When I built up FarSports rims with 12mm nipples they were a litle short- the wrench flats are right at the rim surface.
The carbon is thicker at the spoke bed than aluminium rims.

can someone settle something for me right?

I received some carbon wheels today (i wont say who from yet, its not necessary) and went to fit my brand new tyres. They are a 50mm carbon clincher wheel set.

We all know they can be a pain to fit new tyres, but no problem, nothing out the ordinary for me. i normally use some shower gel as lube to slide a tyre on. Ive fitted probably 30-40 road tyres and probably 8-10 or so on carbon clinchers.

Anyway, today I was fitting the first bead into the wheel, worked my way round until it was very difficult to managed with just fingers. I have some park tools tyre levers so i used one to keep one end of the tyre in the same place, and pulled with my thumb. As i worked the tyre with my other finger, the side wall of the clincher just crumbled. It felt ridiculously weak and literally crumbled.

As ive said, i'm not inexperienced in this area, also, im a mechanic by trade, so Im very good and careful with my hands. I just wouldnt expect this at all from a properly manufactured wheel, carbon or otherwise. You can safely use plastic tyre levers and I always have without any problems.

Now ive informed the seller but I am yet to get a reply. I dont want to name them, this post isnt about this. I just wanted to get like minded peoples opinion on the matter. the seller hasnt had chance to respond yet with the time difference I guess, but I am definitely hoping they replace the rim and at least contribute to the rebuilding cost.

Pretty gutted, I waited nearly a month for these wheels! :(

First thing is to inform your credit card company you're disputing the charge. Once the dispute is open don't pay for the wheels. If it's PayPal you still probably paid via a credit card, don't rely on a Paypal process, go right to the CC company. Insist the seller send you not just a rim but a new wheel, if they want the old wheel back they have to pay for the return shipping. You shouldn't have to be out a dime on this.

Keep or get all the sales or marketing literature from the company re: your wheels, their stated guarantee, all correspondence. Take pictures of the wheel, the failed area, etc.

Obviously check the other rim carefully because maybe you'll need two new wheels.

My credit card company has never refused a charge back when I've had a problem, yours probably won't either. You're in the driver's seat.

I am gonna try out tubular u sharp wheels.

I am new to tubular version wheels.

Need some advice.

Thanks in advance.


Not the 25mm, but the 23mm wide carbon clinchers - if you trace back to page 11 of the thread you'll see the photos. Got them in March this year, must have put 3000 miles into them now. No issues, brake tracks still solid without going concave, tensions still great. Been a pleasure to ride and race on. I'm tempted to get another pair so that i dont have to fuss around with swapping from the road to the TT bike.

Payment and shipping absolutely fine.

Yeah, braking is my major concern. Though if I do get these, definitely won't be using them for steep and windy roads. Not like I ride the brakes when I descend either. Anyway, any chance you may take a few pictures, preferably a few showing the break area and the rest of the rim? Thanks for the review! Do come back with another one after putting more mileage on it :oops: .

I keep insisting on more porn being added to this thread. What I am assuming is happening is that those that have purchased these wheelsets are far too busy off testing them to be bothered to take a few photos and post them in here.

Therefore...

I can do all of the hosting and posting of any pictures you send me (if you are not so inclined to do it yourself). My email address is ::

Lets porn this thread up some!!

or in wheel form:

Has anyone tried these rims? It's a structural carbon fairing--the nipples mount into the carbon part. I was looking that this might be a great all-around wheelset, especially with a powertap. I know it's not WW-friendly at 1949 g/wheelset, but a 25mm wide rim + alloy brake track kind of makes me happy. Kind of a 404 copy, all said and done (although probably gives something up aero-wise)
