Is it worth buying a high end light bike (8.5 kg) from 80' vs recent mid range bike (10kg)

Although I support keeping older bikes in circulation in general, this particular bike comes with some caveats. One of my riding buddies had a very similar bike. The Vitus 979 is a bonded aluminum ...

What is this device attached to the seat-tube?

Are you sure the upper part has not been sliding down such that we can really take a clue from the distance between the two parts? I suspect that the two parts of the fixture are meant to hold an air ...

Its a Giant Sedona, probably from the 2000's. But that information is not very useful for replacing the saddle. If you look up underneath the saddle, there will be two parallel rails, and the ...

Trying to match up a new seat for my bicycle and having difficulty finding one that will work

The stickers tell you it's a Giant Sedona. To me it looks like a fairly old model (they still make a similar hybrid under that name, but with suspension). But you don't need the model details to ...

tubular tire replacement

No, as offered by @NoCo, is the correct answer. This merely offers some additional information. When you're talking about "normal tires," you mean clincher tires with tubes. These will ...

Vintage Armstrong Bike - Garden fixure?

It's a rather nice looking functional bike with probably a 3-speed hub. It seems rather a shame to turn something that's quite attractive and functional into a piece to survive the weather/seasons in ...

Are older road bike parts compatible with newer standards? How do older and newer bikes match up performance wise?

Upgrading an older bike is typically not economical. Parts are typically not cheaper. Parts are not as available. That drivetrain is not compatible with a modern bike. Bikes have gotten better. ...

Why are post ~'80s bike finishes so "dull"?

This is not a complete answer, but one factor certainly is that nowadays bikes often use powder coating as their finish, rather than liquid paint. Powder coating has signifcant advantages over paint (...

There are three common causes for erratic steering at low speed. A possible cause, but the least likely, is that the head stem is too tight. When not on the bike try turning the handlebars. If the ...

Do forged alloy crank arms suffer from age-related fatigue?

Aluminum has no fatigue limit and thus it is impossible to make an aluminum bike part that won't fail with enough use. Fatigue accumulates with load, not time. Good forged cranks with designs that ...

What is the “clip ring” part on my hubs?

Is there a small hole that was covered by the ring? If so it covers a lubrication port. Many old Raleigh, and other utility type hubs came with such a port.

Replacing vintage bike tyres

No, that person was confused and you have it right. A new 700x25 tire will fit the same as what you have. Often 40 year old wheels will need new rim strips while you're at it.
