Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Seems odd to show a discussion about a 2012 R3 frameset vs a Workswell and then use the price of a 2015 R5.

About the Cervelo small parts. The printing on them is embossing done in mold. If they can get essentially authentic frame molds, they can get the small part injection molds too or at least access to them.

True. It is comparable to the R3 frameset as they are approx the same weight. So $450 vs $2000 is a more accurate comparison.

Yes, of course. I'm just pointing out that one isn't any more difficult to come by than the other. Though if the injection mold for small parts were commissioned by Workswell for these frames, I doubt they would have had Cervelo cut into the steel.

Why wouldn't they? They would know there's almost no chance they'd lose an IP case in Chinese courts, which are pretty (in)famous for not noticing similarities between two objects that look essentially identical.

But if they were going to go through the trouble of counterfeiting small parts that most people won't notice, why not just throw Cervelo paint job on the frame?

Wait, wait, wait. So you think it's perfectly reasonable that you're getting a grey market Cervelo frame, but that there must not exist a grey market for cervelo plugs?

Those plugs are probably exactly as shady as your frame, and have an equally uncertain production origin.

Face it, unless WW provides you with and admission and pictures to back it up that they are producing the real cervelo frames from the same molds as your bike, there's no way in hell you can justify drawing that conclusion.

Because they are savvy and understand what most buyers actually want - something that's cheap because it got snuck through rather than a bike that sits in a bicycle version of the uncanny valley because the paint job never quite matches exactly. Small parts with a logo would add plausibility that it is actually a Cervelo. They don't really want anyone other than the buyer to notice, but they want the buyer to notice. This hypothetical situation would hypothetically generate a lot of hypothetical word-of-mouth hypothetical advertising.

Edit: None of this would imply that the frame is a deathtrap like some of the "replicas" turn out to be. It is most likely a reasonably small risk to ride, but it would be a way to stand out in a market that's getting more crowded as time goes by...

1. There is a small risk involved in riding any bike. There is greater than a small risk when your riding involves roads with cars

2. I hit some more twisty decents today (only topped out at 34mph today) and felt perfectly comfortable. Precision handling and no wobbles. Of course the WW bike does have carbon cups integrated into the head tube and fork with integrated crown race so no glued in aluminum cups like knock off frames in some of the recent scare tactic articles

Not at all. I have no idea what I'm getting. I'm open to hearing all possibilities even the silly ones I conjure up.

IS ti not possible that the pieces marked as Cervelo are just real Cervelo parts they purchased to help guarantee fit and finish of the final product?

In an classic brainstorming session that idea would get equal treatment to all others during the first round. It is not outrageous, but it is a bit less likely than many other ideas about this. IMO

Yeah, I own a 2012 R3 Team. I bought the Workswell to be a commuter bike and I now ride it all the time and the R3 sits in the basement.

Here's why:
- The Workswell is a copy of the newer generation of Cervelo R series frames - Internal cable routing and the new more aero tubing. My 2012 R3 has external cabling and squarish tubes
- My Cervelo has Ultegra 6700 and the Workswell is 6800. Forget about the improvement of 11 speed, 6800 shifts much better. Especially the front derailleur
- My R3 is a 56cm and the Workswell is a 54cm. The 54 is the right size for me. Why did I get a 56cm R3? I told my Cervelo bike fitter that I had experienced a sore back in the past. He went super conservative and said a more upright position on a 56 would be better for my back. Well, I've long since slammed the 56 with no sore back and the saddle is so low it looks stupid. The Workswell 54 has a better look for my fit and is a little more responsive.

The Cervelo wins here
- Stiffness. I believe the Cervelo is stiffer. I've not been able to tell the difference riding but if I stand next to the bike, crank on the front brake, and step hard on the NDS pedal there is a little more flex with the Workswell.
- Carbon layup. It's gotta be better, right? Unlike the Workswell copy the new Cervelos have a carbon cylindrical shell for the bottom bracket and internal bulkheads.

Summary
Overall the Cervelo is a better frame. For me the sizing and group set have made me shelve it in favor of the Workswell. When you factor in the price the Workswell is just an awesome bike.\

The other thing I keep coming back to is the fact that Workswell provides Cervelo branded plugs and cable stops for the frame. This means they must have a box with hundreds or thousands of those official Cervelo parts. How does a company come across those unless they have an official relationship or had an official relationship at one point? I would think you would at least have to have a dealer relationship with Cervelo to purchase those in bulk
Where is this WW forum? Is your thread referring to this?

Just ordered mine today
$529 delivered with a simple, but custom paint job/colors. I wanted a light blue bike with inside of fork/chainstais/seatstays in red.
I tried to quote a paint job here in US, got quoted $650 for the same paint scheme

Understand it's not about design. Anyone can design something that doesn't break. It's about build quality and consistency. Name brand recognition cuts both ways. If no-name china company has a problem with their frames breaking, they quietly change the frame, change their ebay name, and start selling again. If Trek has a problem with frames breaking, it becomes news and they issue a recall so nobody further is hurt.

China has a lot of expertise on carbon composites. This is undeniable. But they also have a rather rickety legal system and a rather shady tradition of doing business. This undeniably enhances the risks involved with buying from them. Even a US company buying from Chinese OEMs mitigates this risk, as there is a quality control buffer between the OEM and the consumer.

Right, and to answer Sy's question more specifically as relates to your answer, destructive testing of one frame out of a 1,000 does not represent an onerous cost, is easy to do and is fine IF the other 999 are all just as good within acceptable tolerances. As Brian was suggesting, it isn't hard to design and build a frame that is durable when properly assembled. The question is whether they are all properly assembled. In most cases testing of every frame is impossible, not just because of cost, but because the testing must destroy the frame or at least abuse it in a way that you wouldn't want to trust it with your safety.
