crazy experiment, 53 and 52 teeth on the crank arm of my road bicycle

But seriously, a bicycle should be used to achieve/maintain fitness and provide some enjoyment out in the fresh air. And as previous commenters suggested, riding a 52 or 53 chainring with a small rear cog, unless you are an extremely strong rider, is a good way to wreck your knees.

Campagnolo Chorus and Centaurus were 52 or 53 in 2004, Avanti and Mirage were 52 in 1992
And I happen to have 90000 km on my 52 14 bycicle, used for 30.years, always 52 14-24
I have a second new modern road bicycle for training and stuff, can't Bianchi/Colnago Vento Campagnolo Mirage compare with Pinarello Prince Shimano Ultegra xxx, no way, different planets; as title says this is a crazy experiment just to make fun
Monza Wr is even better, and different.
To be honest ... I emotionally prefer the old Colnago, but Pinarello offers better performance and comfort, while Monza Wr offers outstanding performance but low comfort.
DiTBho:
The central movement is problematic .... Four different sizes, tools, and incompatible ... Oh man.
I just bought the wrong part. You understand it when it is late.
It won t stop me.
The hack goes deeper
DiTBho:
Good news, I also got 53 and 39 for free.
39 will be useful for rpm training, after this experiment.

90,000 km on one frame is impressive.
Wouldn't expect carbon to last as long as that steel does.

Yup, bought that carbon bicycle because ... well because modern bicycles are that way, but I don't like carbon, it's fragile and it feels toy-ish when you compare with steel.
There are several kind of steel frame, for sure mine was not top-premium but rather an alloy of steel and other materials.
You see it when you see rust. Steel doesn't oxidase that way, but iron does.
The central movement is all corroded, so are other parts, and it's not fixable. That bicycle is a disaster after 90000 Km. But hey? It lasted more than expected.
90000 km on one frame probably lasted so long because every time I was outside and took the rain ... I went back home to clean, dry, pass special products, etc.
For a while it worked, but there is nothing to account for the wear.
We did a lot of stuff together, visited far places, had nice time.
Now it deserves a special place in my garage, glory and peace.
Hung it on the wall :-+
