How does a colnago master descend

[cd_davis]

While living in Singapore, I bought a 53 cm Master Olympic (X-light) in 1995. Still own it with original 9 speed DA and straight steel fork. I've ridden the bike in NZ, both islands, the Veneto area of Italy and in New England. All can be very hilly with multiple types of road surfaces. Very, very stable on the downhills, tracks true. Although heavy by today's standards, you can have total confidence in the bike going where you steer it. BTW I weigh 155-160, season dependent.

Mid 80's Master, no wobble as far as the highest speed I've ever done on it (around 40mph).

Yeah all my friends ride 55cm or smaller bikes and they never have issues. I have had it on steel bikes and especially a ti bike I had . It's always going down a fast descent 40 plus mph and I get a gust of wind or hit a small bump and the bike starts moving back and forth and hitting the brakes makes it worse.
Pretty scary

I have a pretty tall seat height at 82.5cm
I'm 6'1" long legs. Most of my bikes are 58-60

I have had 3 colnagos 2 masters I never rode because I convinced myself they where too small and a c59 which was a great bike and descended great no speed wobbles.

Btw I'm a 180lbs

I have a Tecnos and its dreamy for sure.

It depends upon the rider.

Too many factors to give a ton of weight to our opinions of a frame's characteristics (which are often suspiciously glowing in every category). I don't think the Colnago will let you down, but you probably have to try it yourself using your setup if you have had persistent issues with this.

Great post. A 'normallly' designed bike generally won't shimmy. Some are almost designed to shimmy..low trail/small tubes. But not a Colnago.

"The inherit stability of the front end of a bicycle is determined largely by trail. Trail can only affect stability in a seriously negative way at higher speeds where low trail (too much rake) can contribute to shimmy"

What size Love #3 do you have? Do you have a photo of it built?
And do you experience wobbles at high speed on it?

[Bantamben]

Here is my current bike and no this bike hasn't had any wobbles it's very stiff. This is pretty typical of my setup the love is a size 60 I think 58.5 TT 120-130 stem 7-10cm of saddle to bar drop. This particular bike is set up at 6 as I've never cut the fork yet.
One thing
Funny thing is the bike that wobbled at the lowest speed was a ton Kellogg designed Merlin agilis titanium it had a tall headtube and sloping top tube. Over 35 it turned into a rapid sign wave trying to shake me off. Really scary. But hey maybe Tom learned from experience.

I'm not sure how that can be. For a shimmy to be continuous, the forward motion of the bike has to continuously feed energy into the lateral oscillations. How is forward bike motion coupled into its lateral motion, other than through the steering trail? I doubt that a bike without trail even can develop a continuous shimmy.
