Specialized SL3 and Isaac kinda too close in design

Notices
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

Specialized SL3 and Isaac kinda too close in design

Hmmm,
Isaac goes out of business and Specialized changes their design to a much more "traditional" design with the new SL3. The weight of a 56cm SL3 and an Isaac Ultrasonic are almost identical. At least if my Isaac craps out, I can pick up the SL3. The top tube, chainstays and downtube are REALLY similar.

I never liked the Specialized bikes with all the logos (great bikes though), but these are more understated.

Most carbon fiber frames have beefy headtubes these days. There are some slight differences in the headtubes if you look closely. Aside from that, the TT/seatstay cluster is totally different, as are the rear dropouts. I bet if you looked at both frames up close, you could find quite a few other differences.
With all the money specialized puts into R&D, I doubt they would steal the design of Isaac. That being said, they contracted a lot of japanese companies (nitto, miyata, 3rensho) in the 1980s and rebadged them with their name. Interesting theory.

I am not saying they are identical but the TT is similar in how in tapers toward the seat tube. The chainstays are very similar in shape and thickness. They don't look like the typical stuff they put out in past. Headtube and seatstays are different, but overall design is similar which I found strange for Specialized who are usually more unique to their own style.

They are different frames. Look at the curved top tube on the Specialized. The Issac's is straight. The seat tube/top tube junction is different, as is the curve of where the down tube and top tube meet, at the back of the head tube.

Specialized is too big to use generic molds.... they can afford their own.

NEVER said it was a generic mold. Just like the auto industry, they take design cues from other companies and integrate them into their own. Fabian's bike is similar to the Isaac design in those pics. Not identical, but similar.

Yeah,
I always thought it looked more like the Fuji SL1. Same bend from the TT to seatstays

Lazy, you are smoking crack. The SL3 looks just like the other Tarmacs.

I agree, a lot of these frames look the same. The Lynskey Helix is the most unique frame out there right now. Not carbon though.

Lazy, there is a lot of similiarity between all bikes. That's not the point. You said that Specialized "changes their design to a much more "traditional" design with the new SL3" and that's obviously not true. The SL3 design is not more "traditional" in any way than any of the other Tarmacs.

The more subdued graphics contributes to the more traditional look. But Versus had a little video on the frame and they were touting a lot of "changes". Nice bike.

I see similarities between all these bikes. But if it's a 2 triangle frame with a few similar features, then it doesn't mean that it's comparable.

Your isaac is fine. Stop trying to prove it's as good as something else.

I am not trying to prove anything about my Isaac. In fact it is not even my favorite bike that I own. I just see a few things that make is look very similar. The Specialized is not as unique a design as what Felt, Giant are currently offering. Like I said, I think the fewer graphics and more solid color of Fabian C's yellow SL3 contributes to it looking similar.

The SL3 looks almost identical to the SL2.

Does your bike weigh 13.2 lbs stock?

Lazyrider's implication: Specialized SL3 is a new direction for Specialized, and just really an Isaac Supersonic which they ripped off from a dead company.
Verdict: no way. SL3 looks like SL2 and SL1. No correlation with Isaac at all.

All those curved top tubes make installing the frame pump a real chore.

The SL3 is the fugliest, stoopidiest, worst bike ever. Now, all I have to do is just repeat this to myself every second of every minute or every hour of every day until I believe it.

No, but a similarly spec'd one is close and the Ultrasonic is as light and better looking IMO.

No,
I said there were similarities that weren't as apparent in previous models. Specialized has been all over the television touting the "REDESIGN" and would probably disagree with the whole "it is the same as the SL2 talk.

Read my first post, I said they look similar in certain areas and that it is a NICE bike. I never liked their graphics before. Too busy and "racer boy" looking. I like the more subtle paint, like a Parlee, Storck or Isaac. That was my point.

Didn't Isaac have a HUGE recall this year...like all bikes made since 2004? I don't have a lot of faith in a campany that has to recall 5 years worth of bikes...would seem like there is a HUGE gap in their product testing...if they do ANY product testing.

They DIDN'T recall the frame or the fork. They recalled the expander plug and issued a taller one as certain types of stems (ones with cutouts and edges) put undue stress on steerer tube.

This coupled with how some people set their bikes up with spacers too high and not putting a 5mm spacer above stem, they did this voluntarily to ensure people's safety. If fork steerer was damaged from improper set up, they replaced fork. But I understand that when you are dropping $3k + for a frameset, it is a little disconcerting, but in the end, it wasn't anything that Giant or Cervelo didn't do recently on some models.
