What is the “correct” tire pressure for your bike? The simple answer is: Whatever feels right to you. Confused? Here is how it works:
In the past, many riders inflated their tires to the maximum pressure rating. Now most cyclists now recognize that the optimum pressure often is much lower.
But what is the right tire pressure? At Bicycle Quarterly, we’ve done a lot of research into the rolling resistance of tires at various pressures, and on various road surfaces.
Frank Berto’s tire pressure chart (above), first published in Bicycle Quarterly many years ago, has received much attention. (Note that the weights are per wheel, not for the entire bike.)
Berto made the chart in the 1990s, when tires were much narrower. Hardly anybody today still rides on 20 mm tires, and even 23 mm are on their way out! At the other end, 37 mm no longer is huge, as many of us…
At Bicycle Quarterly, we’ve been testing quite a few titanium and carbon bikes lately, and even a bike made from bamboo. We really liked most of these bikes. And yet our own bikes continue to be made from steel. Why don’t we ride carbon or titanium (or bamboo) bikes?
We choose steel because this material allows us to build custom bikes that are dialed in to the nth degree. High-end steel bikes have benefited from decades of research and development. They now offer a performance that is difficult to equal with other materials. With performance, I don’t just mean speed – although the best steel bikes have no trouble keeping up with ti or carbon racers – but also handling, reliability and all-weather, all-road capability.
Steel tubing is available in many diameters and wall thicknesses, so it’s easy to fine-tune the ride quality and performance of our bikes. For example, my…
For cycling safety, it’s important to have front, rear, and side visibility, and possibly a horn and cameras.
The following is a list of safety accessories:
front bike light
rear bike light
front helmet light
rear helmet light
front spoke light
rear spoke light
There’s 10 items on the list which doesn’t include non-safety or non-electronic accessories such as smart locks, navigation devices, hand warmers, power meter and mirrors. Some cyclists may even install more lights for increased brightness or visibility.
My opinion is that that those features should be in fewer units for convenience. A possible design might be having one larger battery pack and one control unit for the bike’s front, rear, and side lights. The same design can be done for the helmet light which can also be used as a spare light.
The problem with half a dozen bike lights is the need to charge many units, the need to press the buttons for each unit, and the need to remove them when parking your bike.your bike. If the conditions change, you may also need to adjust the light settings for each unit to conserve energy or improve visibility.
If only helmet and bike lights are upgraded to be complete, the number of units can be dropped from 10 to 6. With fewer units, it’s easier to remember to charge them all, turn them on or off, and store them which encourage its use, possibly making cycling safer.
I find it easier to manage with fewer bike lights.
For cars, a single battery powers most of its accessories. Why shouldn’t bike accessories be powered the same way too?
