Is Scandium stiff enough?(8 posts)

Is Scandium stiff enough?Slice
Jul 19, 2001 11:58 AM
I was interested in a new Interloc Scandium frame with OS tubes and carbon seatstays. I've heard Easton Scandium is not as stiff and Easton Elite because the tube diameters are narrower. But the Interloc has OS tubes so it is possibly stiffer. Should a big guy (180 lbs.) consider a Scandium frame at all?

I can't comment on Scandium, but my LBS has one of the IRD Scandium frames in his shop. It's very nicely made, very clean looking, very lightweight. He's recommending it to a guy who is about 5'10" and probably 170 or so.
Where did you see the IRD Scandium-Carbon?slice

I've only seen it on their website.
Supposedly they won't be available for a month or so.

At the LBS I frequent in Dublin, California. Silver with white decals and Columbus Carve stays. I held it in my very own hands, even. It seems like a really nice frame.
If its stiff enough for Casagrande....Thioderek

I have 2 DeRosa Meraks made with the Dedacciai tubing. They are the 2 lightest and stiffest bikes I have ever ridden. I ride the bike every day including the recent CAR 8 which was 600 miles in 7 days. I found the bike stiff enough, tight handling and just a dream to ride over those 7 days. you would be hard pressed to find a nicer ride. Of course I am only 6ft and 163-165 pounds. There was an actual weight limit guideline that came with the new bike packet that listed the maximum weight as 80 kilos for the Merak. The Ud can only handle a maximum of 160 pounds I think.

Considering your stats, you might want to do a lot of research with the framemaker before making the plunge.
no Scandium in Dedacciai tubesmmaggi

According to the Dedacciai website, there is no sign of Scandium in their aluminunm alloy tubes. As a matter of fact, nowhere on the website Scandium is mentioned.

All aluminum tubing from Dedacciai contain the elements Cu-Zn-Mn (Copper, Zinc, Magnesium) along with Aluminum. There is no indication that Scandium is present.

The SC61.10A tubing is no different except for the fact that it has a KET (Kinetic Energy Treatment) surface (whatever that means).

I suspect that the SC in front of the 61.10A is deceiving many to think that Scandium is present in these tubes. The fact is that it's not.

I think KET is just a cute marketing term for shot-peening or shotblasting. They shoot little particles at the tube surface to evenly compact and harden it. "Kinetic" refers to those hi-speed moving particles.

Well, I just recently went from a steel waterford to a Easton Scandium frame with carbon rear seat stays and I was very impressed by the stiffness and overall comfort of the Scandium. Charlie from really helped me make my decision to go with Scandium. I am 6' tall and 163lbs and this bike is plenty stiff for my size and im sure you would be fine on one too. Just go to Charlies web site and put in your info and he will make sure that would be a good choice for you. There is a picture of my Scandium in the bike picture post area and its titled Empire if you want to see it.
