What happened to riding with no hands?

Nothing happened or changed. It's just your observational bias coupled with different demographics preferring different bike capabilities. Many children's bikes have relatively relaxed geometry, ...

Why Did Old Soviet City Bikes Have Longer Frames in General

A soviet bicycle is designed to carry very heavy loads on the rear (like two large containers of milk one each side). Hence the rear wheel and the pannier are moved backwards, giving more weight of ...

How does fork offset affect bike handling?

Offset primarily affects your mechanical trail - that is, the distance between the imaginary straight line going through your head tube down to the ground, and your tire’s contact patch. Normally, the ...

What happened to riding with no hands?

I think there's a large element of selection bias, combined with changes to roads and traffic rather than bikes. When you were a kid you used to ride with kids who rode a lot, probably on fairly ...

Apparent pedal force improvement from swept back handlebars; why not use them?

For one thing, the aerodynamics are terrible. For another, most cycling is not dependent on peak power, but on sustainable power, for which leg strength (or body strength) isn’t as important as ...

What makes a bike good or bad for climbing?

This is not an especially aero bike, although it does have some aero-looking feature (which does not mean it was in fact aerodynamically optimized). There's also nothing about it that makes it ...

Why Did Old Soviet City Bikes Have Longer Frames in General

The Ukraine bike looks like a copy of older British roadster bikes, only in more 80s-appropriate colors. It could be speculated that the longer frame and sprung saddle were more comfortable on bad ...

Why are endurance bikes so bulky or wide nowadays?

Second moment of area increases with distance to the power of 4. This means a tube with a wide diameter and thin walls is much stronger against bending or torsion than a narrow tube with thick walls ...

Why Did Old Soviet City Bikes Have Longer Frames in General

Why are endurance bikes so bulky or wide nowadays?

I disagree that Endurance bikes look "huge". Taking your example of Canyon, the current model of the endurance has very slender tubes by modern standards. However there are a number of ...

Cycling jargon: "relaxed geometry", "slack geometry", and "aggressive geometry"

Not everyone uses language the same way. Also, there's no central body putting out a dictionary of what cycling terms mean. Thus, I can only attest as to what I think these terms mean, based on my ...

Were older bikes generally longer?

Yes, the first "safety" bicycles had longer frames and rear triangles than current performance-oriented bikes. For example, have a look at this photo of world class track cyclists from 1907: ...

Are bikes with aggressive positions required to achieve high fitness levels when training on a bike?

TL;DNR - The bike you will ride most often is the bike that will get you fittest. Fitness and power transfer are unrelated. Your bike fitter is presuming you want to make the most of the power you ...

Install suspension forks on non-suspension bike

You might be able to fit a suspension fork on your bike, depending on frame geometry, but I think it’s likely you will not be able to. Frames designed for suspension forks locate the head tube ...

What happened to riding with no hands?

The biggest influence on how a bike steers is 'trail'. Trail is the distance that the contact area of the front tyre on the ground trails behind a line drawn through the steering axis to the ground. (...

On WSD bicycle shouldn't the seat tube be longer and at a shallower angle?

A few thoughts: moving the saddle back to compensate for a too short seat post is not the right approach. Seat tubes have a minimum insertion length mark, it's important to respect it, but as long as ...

What is the difference between a horizontal top tube and a sloped one?

What is the difference between a horizontal top tube and a sloped one?

Its all about inventory and stock levels. Historically frames came in increments of 2 or 3 cm. So one model might be stocked in 48/51/54/57/60 cm or 48/50/52/53/56/58/60 By having more adjust in ...
