Hi everyone, decided to stop lurking and add to the data pool since this forum has been so helpful to me.

I ordered R35 with DT350 hubs on March 3rd.
Received it yesterday on April 15th. So, about 40 days with the cheaper EMS shipping.
Front weighs 662 grams
Rear weighs 801 grams

I also ordered R45 rims (rim brake model) on March 15th
Received it on March 27th. So, about 12 days for a ready stock rims with FedEx shipping
Sorry, I forgot to weigh it before it was built.

Mine went to “building” today. Hopefully I get some pictures soon and they throw them in the mail.

Sun came back out, got a couple shots that show the satin finish better, they look great!

Anyone run the new width of Conti 5000 30C on the WR's? I'm curious how wide it is on the rim.
Or, I guess is anyone running Conti 5000 32C and have the width measurement?
Has your WR50 been stuck in “CNC Machining” for the last three weeks like mine?

Mine has just gone to "Sanding" today from CNC. I think ours are in the same batch?
Patience. It took me 4 months from date of order. Parcel tracking says I'm going to get my wheels next week!
4 months!...

LB promised me to ship the wheelset out within this week. Can't wait!

edit: wheels finally shipped !_!. 9 weeks since order to ship out.

Got my pictures today. Super excited to get them on the road and see how they do in the sometimes nasty winds here in southern Spain. Hopefully they ship today and show up sometime next week :).

WR50/65, DT350, 28h, no holes

I saw new hubs available, ARC MT-032 F. Has anyone heard of those before?

hello I'm Gianluca from Italy! I have some questions to the owners of lightbicycle wheels,
but first some personal specs: I'm 80kg, I ride a racing bike with rim brakes, only asphalt, I'm going to use tubeless 28mm tyres, looking for a medium aero rim 40-50mm:

1) most important: are these wheels good for rim brakes? has anyone had any issues?
2) v-shaped AR series vs u-shaped R series, which one is the best?
3) for 28mm tubeless which one is better: 23/30mm inner/outer width or 21/28mm inner/outer width?

Thanks to everyone is going to help!

Cheers

Cheap Chinese hubs. Chinese - not Taiwanese. Mainly sold to the West through AliExpress.

Not sure how good or bad they are. There aren't many Chinese hub brands. Though a few of the Western & TW companies do have factories there, hubs are still mainly made (and designed) in TW.

28mm tire - is that actual measured width of installed tire or do you mean 28c tires.
If the question was about 28c - their actual width will be >30mm. In this case, the 23/30 and 21/28 rims are not recommended.
Another question is that you`ve mentioned is about rim brakes. Most rim brake road frames don`t have clearance wide tires.

I use a 21/28 AR wheelset with Continental GP5000TL 25c tires. They measure ~28mm and sit flush with the rim. With my weight of 74kg, I inflate those tires to 65psi(4.5 bar) front and 70psi(4.8bar) back, which is really comfy. I am a bit lighter than you so with this combo you`ll probably have to pump a bit more air.

On the other side - guys here say that GP5000TL 25c is a better fit for the 23/30 rims since this combo follows the 105 rule.

hello hartmannce, thanks for the answers!
yes I meant 28c tires. I actally use victoria rubino pro 25c inflated 7.5 bar (not tubeless) and I have a lot of clearance...my frame should fit tires till 32c, 28c should not be a problem.
if 25c tubeless becomes wider on 23/30 rims I could keep on using it, I would have liked to try 28c to gain some comfort.
what is 105 rule?
any info about LB rim brakes reliability?

thanks

105 rule is about the most aero rim-tire combo: if your tire has X actual width - the rim width should ideally be X*1.05. That is the theory.

The braking should be as good as any other brand and better than many.
You do need to be careful with 23/30mm rims on a rim brake bike. 28mm tires will get close to the brake caliper or frame on some models. Of course some frames have good space and can do it. I can fit up to 32mm measured on my Factor rim brake with EE direct mount brakes. Which brake calipers will you use? Some are borderline with 30mm rims.
As for the 105 rule, it only matters if you are trying to optimize for every watt. I use 28mm Vittoria Corsas on 28mm wide rims on days that I want more comfort. I even use a 30mm tire on the rear sometimes as well. There are no issues in crosswinds, another reason you don't want the tire much wider than the rim.

1) Brake power is good in dry, above average in wet but low in heavy rain (most carbon rims are low in heavy rain). Farsports have a better brake track.

2) Considering the tire-rim combo and the specifiec shape of AR and R (rim brake), the wide curved-V-shape of AR has a more relaxed 105 rule than the U-shaped R. I have AR56-28/21 and other open module rims whose shape is the same as R (38 front and 50 rear). The U shape is more stable in small yaw while the wide curved-V shape is more stable in big yaw even with a deeper profile. The curved-V is pushed left and right like an oscillator in small yaw, kinda unstable. One needs to get used to this oscillator behaviour which only happens in small yaw and then will find the handling easier as the side force is actually smaller than the U shape.

3) Make sure the clearance of both your frame and brake is enough. My frame and brake (EE G3 DM) have clearance for 32 mm (real width) tires, but EE works better with the rims whose brake track width is no larger than 28 mm.

For 28c tubeless, some would measure 28 mm on a 21c rim but most are wider while most others would be more than that. For both aero and comfort, 23/30 is better if you stick to 28c tubeless.

Anybody seen the new Bontrager Aeolus specs? Looks very similar to the AR56. They were already fast wheels and now even faster. No need to spend that much though since the AR56 are pretty close in performance while being only a fraction of their cost.
