Open mold wide profile carbon wheels

[RocketRacing]

Velocarbon “clarified” when i asked for the width at the brake tracks. Apparently, the outside of the rims are 27mm, and the inside are 26mm. So that confused me more, so i asked the max width of the rims, the width at the brake tracks, and the internal width of the rims. Their reply was to look at the diagrams, and buy the items if ok.

Looking at various online chinese rims, they all look close, yet different. Maybe they are all the same, maybe each is slightly different. I find myself not trusting anything as there are so many errors in the item descriptions, and most photos are stock photos. For example, carboncycle shows photos with 18k carbon, but only allows you to order 3k or 12k.

Here are some versions i found from various retailers. I am being picky because i want to be sure i am ordering what i think i am ordering, due to shipping costs (and costs if specs are wrong and i need to return). The last image is the ones i am considering.

All these drop shippers seem to be loose on accuracy, and shipping from the same area of guangdong shenzen.

Chinese riders arent't so heavy and chinese roads aren't that horrible.

Thats why chinese rims basically max out at around 28mm wide (25 brake track).

I saw in another thread that you are 130lbs RocketRacing. That is a good weight for such a width. Only exception is if you intend to do horrible.

It's funny how they seem to be not only copying the big brands, but each other as well. I'd say from that bunch at least Light Bicycle is a legit manufacturer. Carboncycle.cc and eiecarbon.com seem to have copied at least the product description templates on their sites from LB.

Light bicycle has a pretty legit website and customer service. To me, all the 25mm rims look the same, and probably are

Yeah, i can get away with a lot at my weight... and a light bike makes legit sense for me!

My roads kind of suck in places, and i also like the rr benefits of 25’s. Thus me wanting 26-27mm rims... for aero reasons. I also plan to get a tt bike, maybe with rim brakes, and i figure that 25cc tires might take some of the sting out of it. If i get a disc tt bike, i would go 28’s with 30-32mm wide rims.

Even if you need to go over the ideal width you can stay on 25c in the front and 28c in the rear for a super cushy ride The aero penalty for going a bit over in the rear is nearly zero amyway.

So I wouldn't worry about the rim width.

If you have a wet climate I'd worry about the brake track. Personally I live in a 99% dry area so it's not a big deal for me. I still am curious to try textured brake tracks simply to try explore what gives more bite on carbon. Also if I join a race and the weather looks dodgy I can opt for something I feel confident on dry and wet.

The expensive wheelsets shine over chinese wheels on braking and stiffness. If you can address those issues in your build you have a killer wheelset. High temp resins are already there, quality is increasing, and now come the brake tracks.

I would just get Farsports ot LB over a no-name Alibaba wheelset. I'd rather pay $100 extra to get something that will mostly be problem free.

Choosing my first set of carbon wheels. Looking at Farsports 26mm wide disc wheels built with DT Swiss 240 and CX Ray spokes 24/24 for a 58cm Focus Izalco Max Disc. Can’t decide between 35 and 45 rim depth. Most rides 100km/1500m plus early morning hills, evening laps and 200km summer rides. 40g penalty for each rim weight. Any thoughts?

[kofsw4]

In case it helps you decide, here's my 56cm izalco max disc with 46mm LB wheels which I also had built with dt 240 hubs.

My typical ride is very similar to yours 100km with 1200-1500m elevation and I don't regret going for the deeper rims (alternative was 36mm) at all, even on the windiest days.

I bet you wouldn't notice any difference in a blind test. If you like the "aero wheel look", go for 45mm. If you prefer a light do-it-all wheelset, go for 35mm.

I was at the same conundrum about a month ago, deciding between Light Bicycle's 35, 45 and 55mm tubular rims for my Spesh Tarmac. I wanted a semi-aero do-it-all wheelset and don't do as much climbing in general as you do. Decided to get 45mm.

Light Bicycle's RRU45T02 rims (20/24h, non-disc) and Syntace HiTorque RS hubs have arrived, still waiting for Sapim CX-Rays and nipples. Projecting an overall weight of 1320g.

45s will be a bit faster over any terrain despite the weight penalty

[iamalex]

Thank you very much for the feedback and photos. You Izalco looks great kofsw4

Leaning toward the 45s

Good evening and happy new year folks!

Approx. 2 month ago received my custom built Farsport FSC50-25 tubeless without hole in rim bed (Powerway R51 hub and Sapim CX-Ray spokes).

Save me a million pages of reading...
Seems like Light Bicycle prices and brand name prices are converging.

Who is currently on the lists in everyone's eyes (not considering braking surfaces):

Near Brandname - Near risk free purchase, but at a cost ($400+/rim pair)
Light Bicycle
FarSports

Value - Seemingly makes a good rim, but at a lower cost compared to Light Bicycle (around or below $350/rim pair)
Sketchy - Probably an OK rim, at a low cost (under $350pair).
Avoid - Quality or price or buying experience are not in line.

anything deeper than the LB 56mm but still 30mm wide about? the LB 65mm is only 25.85mm wide, which is on the narrow side these days
