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

Ten minutes off 200km is a pretty big deal for a racer.

Who said anything about Banned?

".....The Return of Aluminum bikes to the real world?" I thought "Real World" meant non-racers.
In any case, I feel the CAAD10 was the return, the 12 might be somewhat of a step away from that.

As for Velonews, first a bad review of CAAD12, then that article about Counterfeit Carbon... Meh, I'm just gonna step back and watch this industry implode like Atari in the 80's. If it doesn't, no sweat off my back, I already got my Pure Fix frame standing by.

If you look at old steel bikes, they have very thin tubes compared to the tubes we see today. These thin tubes allow for vertical compliance.

Also, in the search for the ultimate aero bike, some aluminum bikes have teardrop shaped downtubes, with the major axis vertical and the minor axis horizontal. This does NOT allow for much vertical compliance at all.

Right. AL is a soft metal. Beef it up enough to make a durable bicycle frame, and it will be harsh, unless you take care to make it thick where it needs to be, and thin where in can be; and use special shapes and thicknesses to compensate. Gary Klein seems to have gotten that down to an art form! (There are probably some other great AL bikes out there too, I just don't know of them)

I'll never understand how Klein was able to make such a stiff bike....that rides so beautifully- with no harshness.

I could practice brazing, and probnably build a steel frame that would ride decently. I could never do the same with AL- even if I were an expert TIG welder.

If that had happened on an AL bike, it'd be toast. A carbon frame would be looking at mailing away to a specialist repair place at a cost of hundreds of dollars, if I was lucky enough that they thought it was repairable.

I'd take a broken carbon frame to my local carbon repair guy for a few bucks and a couple of beers. Closest guy to repair steel would be about 90 minutes away and I'd be queued behind custom frame building.

You happen to have a carbon builder local to you. That's not a solution that works for everybody. There's a custom frame builder local to me who works all in steel. I don't know where I'd go to get carbon done.

But the thing is, if I had a broken steel bike, I could take it to any halfway competent professional welder, who needn't even have any experience with bikes, and he'd put it back together and have it, if not pro-race worthy, then at the very least capable of doing basic duty as a bicycle. The LBS I took my old bike to weren't frame builders, but they had welding equipment, and could fix steel bike frames for a very reasonable price.

With Al frames, you need to find a MiG or TiG welder with specialized equipment and who can put the whole frame in an oven. CF is a whole 'nother level of specialization and equipment again.

You don't see the absurdity in that?

It's one thing to do a minor repair on 4130, it's something else entirely to do a permanent repair on modern thin guage heat treated steel alloys.

With Al frames, you need to find a MiG or TiG welder with specialized equipment and who can put the whole frame in an oven.
Yep. Of course most steel frames are TIG welded these days as well.

CF is a whole 'nother level of specialization and equipment again.
Unlike carbon frame building, it's actually not that expensive to do carbon frame repair.

The 105 model does but none of the others. A pair of 5800 brakes won't set you back very much at all.

+1. I replaced the Tektro calipers on my CAAD10 with 5800. About $25-30 net after unloading the stock pair.

I like a lot of the new steel bikes. Wish they were more accessible.


Anyway, I put a deposit on a new Caad12 then canceled. I was going to get the non disc version. Seems like this bike was built with disc in mnd and the non disc versions are an after thought. I am going to wait till some folks put some miles on them. I may pick up a Caad10 if they dont meet expectations.

I think some of the guy's in the Cult of CAAD thread have already given rider feedback. Unless you meant extensive mileage.....

Heck, I'm still riding my CAAD9, the last of the real Cannondales IMHO. It really is a terrific bike, and it's managed quite well during my 160 lb weight loss - I started at over 400 lbs. I had wheels built for it and my fit has changed a couple of times, but the frame is in great shape and rides well. The CF fork helps with the ride quality I'm sure.

No, you were lucky that YOU thought it was repairable. You can find some putz to do a jackleg job on just about anything without any trouble. Does your bike look like new now too. Is the weld as strong as the original tube connections on the bike? What possible similarity is there to your letting some doofus weld on Columbus SL, burn up your bike, and hand it back to you saying, "There, good as new," to a competent structural and cosmetic repair done by a qualified craftsman...on any material? Did he use just the right CrMo rod, TIG setup, and such? Do you think no strength or appearance was compromised in the process or don't care? Or that the folks you are discussing this with mean the same thing as you do when they say "repair"? A little self-awareness here, please!

We're comparing jobs that end in a like-new product done by folks who have a reputation for knowing how.
