Anybody riding a bike speced with the Columbus Carve wishbone rear triangle? Desalvo is going to be making me a steel oversize 60cm and I have the option of specing out a CF rear triangle. I was looking at the columbus website and came accross it. http://www.columbustubi.co
It looks mad dope and I love the idea at least. I found a few frames speced with it, but no rider feedback.

I'm riding a custom Carl Strong with the Columbus rear. It's stiff, it looks cool, it doesn't do anything for the ride. But I did say it looks cool. I did it on sort of a techno-whim and it turned out to be a pretty neat bike.

This is what it looks like -

well let's see

disadvantages
a) costs more
b) creates bond spaces that may fail
c) removes the sweet feel of steel under your backside (why get a steel frame?)
d) most likely heavier

advantages
a) looks cool (as stated)
b) may stiffen up rear end (is that good?)

IMO I wouldn't be too worried about the bonding issues these days and I actually found the Columbus Muscle rear end to be soft or dead in terms of acceleration. At the bottom line we still agree that ist ain't worth it though.

agreed Rocco

but ya have to admit a bonded rear has a higher chance of failing than a Tig Welded or brazed one.

Yeah perhaps though I've cracked a tig welded steel frame and I've never had carbon bonded part or frame fail on me.

wishbone

The Carve is unique in that it is a wishbone design. I know the pros and conf of the CF, I was actually asking about the wishbone design more specifically.
Thanks for the input though.

It won't make any difference to the ride or performance. Carbon stays are designed to look cool, and that's it. Plus, in many cases, they actually lower the cost of production for the manufacturer. It's great for them. Looks cool. Sells for more. Costs less.

Don't want to hijack this discussion, but I have to ask.
Did Strong build your frame all himself? He does steel, Ti , and now
bonds CF to steel. He must be talented. I was looking at him to
do a custom Ti for me. I wish I could meet him. He does respond to
email and I guess phone calls.

right and wrong

no way it costs less to put on carbon rear stays

BUT it does not seem to improve ride or performance
just looks cool

I think full steel, full carbon, full Ti, or Full Aluminum makes a lot more sense

Actually, for the full Carve rear end, there is much less labor for the builder, since the seat stay/chain stay junction is already made, and the builder doesn't have to expend labor on the brake bridge. So, there is probably a cost savings.

But...

the builder would pay thru the nose to buy that rear tri
carbon costs more than aluminum - period
I am not saying it is better - just that it costs more

myself, I prefer high grade steel
but carbon does cost more; use less - frame costs less

Yes he did. That bike is from 2002, so it's not a matter of him bonding CF to steel "now." He's been doing it for a bit.

He's a great guy to work with, hands down. Never kept me waiting, answered all my stupid questions (with patience) and built me a great bike at a great price. If you're seriously shopping, you'd be hard-pressed to find a better partner in a custom project.

Correct me if I am wrong here, but the cost of a frame is largely based on the cost of labor and tooling to make it. A steel tubeset is pretty cheap, the prepping of the tubes, setting up the jig for welding or brazing, the finish work on the joints, heat treating if necessary, and the painting are the big costs because they involve human beings. If you could take a carbon rear out of a box and fit it up, you have eliminated 8 or more welding/brazing processes.

yes - you are wrong

in the case of Aluminum frames at least

weilding together an aluminum frames takes minutes
not hours
and most are done in china or taiwan

a few minutes of a workers time in china will not get you a reynolds 853 tubing set
nor the material to make a full carbon frame
