TECH

At only 475g with an aerodynamic 45mm deep profile, the U45 is our jack-of-all-trades rim. Whether you are chasing KOMs on the mountain or racing your buddies to the next checkpoint, this wheel is for you.

With a 45mm depth, this wheel offers all the aerodynamic benefits of a much deeper profile in a lighter package that’s easier to control in crosswinds. If there’s climbing to do, these could be your best choice.

I'd recommend Lightbicycle to anyone based on that experience and the quality of the rims!

Emacdo: Bought a set of 35MM and 45MM rim brake rims and built them up over the winter with a pair of Campy Electron hubs (completely rebuilt). The 35/45 configuration is a great all-rounder setup - climber in the front, aero in the back. They were fantastically easy to lace up due to their very tight construction tolerances. Finally have been able to take them on a couple of shorter rides in the last couple weeks (now that Spring is here where I live) and they were fabulous. Rode 90+ miles today on chip seal and washboard roads and the rims handled really well. These are now my favorite wheels. I can't say as much about the Conti 5k tires, but that has nothing to do with the rims (switching to a set of Vittoria Corsas after today's ride). The roads around here are passable at best, so I have done my best to beat these rims around and they have responded perfectly. I can't wait to put many more miles on them.

Roger: Rims: R45/R65 Mixed Combo Non-Disc Hubs: Acros Nineteen RD 24/32 Frame: VPACE T1R Titanium I ordered the rims separately according to my own wishes (3K twill vertical no decal) and built them by myself. The wheels perform very well under all conditions. It's always a pleasure to ride with them.

Would it be possible to go with differentiated rims - 35mm front rim and 45mm rear rim? Is the cost going to be the same ? Thanks, Clod


LightBicycle 2020/12/22

Hi Clod, Yes, we can build a mixed size wheelset 700C for you. Could you be more specific about the specs that you are interested in? I will send more details to you for ref. Thanks, Lightbicycle

I also wanted to do custom graphics -- just single decal where the valve is. Rim Model: R45 Size: 700C Series: Falcon Use: road/CX Type: Clincher non-disc Inner/outter width: 17.9mm/25mm depth: 45mm Hubs: carbon-ti x-hub Driver body: shimano road 11s Spoke: Sapim CX Ray Nipples: Sapim aluminum black Brake system: non-disc grooved graphene surface finish: Satin weave: UD Center Channel Hole: Without holes Decal: do you have a gold foil option? otherwise just stealth grey Brake Pads: add brake pads Thanks!

Mike 2020/10/01

Hi! Is is possible to have just the valve stem logo decal and not the larger decals on the wheels? I am looking at purchasing either the AR 46 or R 45 wheelset. Also, is it possible to get either of these rim brake wheelsets with DT 240 hubs? Thank you and enjoy your day! :)


LightBicycle 2020/10/02

Hi Mike, Thanks for your inquiry!Yes, it is okay to have only valve logo on rims/wheels. When you place the order, you can leave a message on the order that "only valve logo please". Then we can see it and will double check with you after receiving your order, to make sure everything is correct. Also, we can take wheelset pictures for your check before shipping. Thanks, Lightbicycle

Hi, I was wondering why none of the wheels have the "North American Warehouse" option, can only see the "Global Options"


LightBicycle 2020/05/04

Hi Sir, We only have disc road rims stock in the America warehouse at the moment. Is there any reason that you prefer the h America warehouse? You can get all configurations from the Global warehouse as well. Thanks, Lightbicycle

Hello Nacy, I have a set of your road wheels bought in 2018 and I Love them. I’am thinking of another set of your wheels for my other bike. Do you send wheelset to Mazatlan, Mexico. If so what is the cost? Thank you Darrell Moquist


LightBicycle 2020/02/08

Hi, I'm looking for a new wheelset and I have a few questions about your return/warranty policy: - If I buy your product, and I am not satisfied with it, can I send the wheelset back and get a guaranteed refund? - If I crash my wheelset that I purchase from you, can I return it and get a discount on a replacement set of wheels? Thanks


LightBicycle 2019/06/17

Hi Seth, 1. Yes, just send back the product in good condition for a refund if the wheelset is new(without riding). 2. A crash replacement with very good discount works well there in common practice. Thanks, Lightbicycle

Jonathan 2019/04/21

I usually run 25mm tyres. Will this pair of wheels be suitable or should I get the 28mm outer width wheels for better aero dynamics?


LightBicycle 2019/04/22

Hi Jonathan, I am Nancy from Lightbicycle. We talked online on weekends. I know your ride 25mm tires. From our research and test, the rim width has to be slightly wider than tire width. Then it has better aerodynamics. So, we recommend you to go for RR46C02(28mm wide/46mm deep) rims/wheels. Do you like 700C complete road wheelset or just rims only? We can quote accordingly for you. Thanks, Lightbicyle

Peter 2019/03/26

Am around 76kg, on carbon rim brake frame, basically riding relatively on flat road for speed. Sometimes, i do like to go for a climb but the gradient we have here is only 11% max and is just around 200m only. Am not sure does it justify for my below requirement or you have better suggestion. Which wheelset do you recommend? WRU45C02 or WR46C02 Can i go for spokes of 16 front, 20 rear? Possible to request without inner spoke holes?


LightBicycle 2019/03/26

Hi Peter, 1. Yes, we can make UST road wheels without spoke access holes on rim bed for you like the attachment. 2. Is it windy at where you ride? What about crosswinds? The WR45C02 provide better aerodynamics in no wind and lighter, the WR46C02 on the other hand with rounded "second" leading edge allows for more attached airflow, which reduces drags and increases balancing side force. You are a light rider and riding not aggressive, both wheelsets work well for you. 3. Do you have any specific hub(Front 16H, rear 20H) that you like to build the wheelset with? Power way R13 hub red okay for you? Thanks, Lightbicycle

Jason 2019/03/20

Keen on these wheels, however I would like to confirm details for a disc brake build. https://www.lightbicycle.com/U-shape-45mm-depth-Hand-built-700C-carbon-25mm-wide-clincher-road-bicycle-wheels-for-tubeless-compatible.html Wanting straight pull hubs as well, aero spokes, clincher. 12mm through axle, 100mm front, 142mm I see also you say 0 offset (symetrical), I assume this is for a rim build, and a disc build will be Asymetrical, yes? Cost and delivery to Australia?


LightBicycle 2019/03/20

Hi Jason, Thanks for your inquiry! For RRU45C02 rims, the rim profile is designed as symmetrical. We do not have asymmetrical for road rims yet. For road rims, asymmetrical rim profile will affect the aerodynamics. So, normally most brands do not manufacture road rear rim with asymmetrial. Please find our quotation as below. It is USD681.40/pair. - Rims: RRU45C02, UD matte, 24H, disc - Hubs: black DT Swiss 350 road disc, front 12*100mm/rear 12*142mm, straight pull, centerlock, shimano road 11S, 18T - Spokes: black sapim cx-ray bladed straight pull - Nipples: black aluminum If it is with DT Swiss 240S road disc hubs, it is USD859.40/pair. The delivery cost is USD58 for one wheelset to Australia by EMS delivery. Thanks, Lightbicycle

Hi, Do you ship to Turkey? If so, are there any payment methods other than PayPal? Because PayPal doesn’t operate where i’m from.


LightBicycle 2019/03/04

Hi Batu, Yes, we can ship to Turkey. The shipping cost would be USD116.5 for one bicycle wheelset by EMS delivery. For payment method, we normlly accept paypal, bank transfer or western union. Which do you prefer? Thanks, Lightbicycle

Hi Helen, Yes, we offer one year crash replacement for road rims. Actually, road wheels will mostly not much crash crack. Only mtb riding will have some crash mostly. Don't worry about it. Thanks, Lightbicycle
