Re: Cyclist dies after crashing into open car door
But very often, the names of the people involved are public, or readily available. This means that if you have details of the road traffic crash, you effectively have personal details.

It's a minor thing but the title of this thread is very alarmist - it almost sounds like a cry for help, an "I'm about to commit suicide!" type thing. Something a bit more descriptive of simply running out of energy on a bike ride would probably be more appropriate...

I’d have thought that JDSK would be best placed to comment on the associated health issues. From my poorly informed perspective honey is near enough neat sugar and consuming neat sugar is probably unwise and so for several reasons. I don’t believe in (instant) energy bars but rather something that’s essentially slow / slower release is what I aim for and to eat something before the dreaded ‘bonk’ actually hits you.

Regarding the energy, many people find it beneficial to have a combination of quick & slow release carbohydrates, along with some fat & protein. This one reason that things like flap jacks are good. They have sugar (or honey!), oats and butter or oil. Energy bars do the same thing, possibly with a more scientific approach to determine how much of which.

Re: "Why is the right at war with cyclists?... "
And that's why 20 years ago in rural Suffolk, I had idiots shouting obscenities at me for the crime of... riding in the middle of the lane? Or maybe it was because I was pulling a trailer?Airsporter1st wrote: ↑26 Mar 2024, 6:46am I would hazard a guess that the author of that piece lives in or around London, where the majority of cyclists, especially commuters and delivery riders, seem to behave in such a way as to invite the negativity.
Of course it is. But politicians have long disagreed upon how to encourage more cycling and whether it should be at the expense of driving. The 'culture war' politics of the like of the Brexit Party, the Reform Party, and some elements in the Conservatives have driven a wedge in where there was previously mere disagreement.
Social media trolls have made this worse, and now there are more idiots shouting obscenities, and fewer folks in the middle, finding compromises, or politely agreeing to disagree.

Re: Techniques for braking on steep descents
Yes, but if you brake for a couple seconds, then cool for a few seconds, you can dissipate the heat more readily. If you drag the brakes, they are constantly generating heat, and have less surface areas to dissipate it.Pebble wrote: ↑8 Apr 2024, 3:02pm
why would periodic braking help ?
On a long steady slope
a) holding brakes at constant pressure so as speed remains at a constant 20mph
b) repeatedly letting it go up to 25 then braking down to 15
c) alternate harder braking from front to rear brakes but keep speed at constant 20
It is the same amount of kinetic energy being transferred into heat.
I do b), though my speed probably varies a bit more than that. If know the descent, I tend to freewheel where I have a long straight section, then brake hard enough before a bend, both for keeping my speed reasonable, and taking the bend. I probably go a bit more slowly through bends than some folks would do, but I am not a fast descender.

Re: Techniques for braking on steep descents
Fins increase the surface area for heat dissipation. The heat spreads through the metal first, so that's a good place to dissipate heat. Obviously, it would be better to do it on the braking surface, but that's the part that's generating the heat.
Fins on the metal backing will do the most good during braking. When not braking, the the pads themselves will be cooled by the air.
edited to add: that said, fins need to be designed properly to be worth the extra weight. the principle works well in other areas; I do not have direct experience with finned pads on disk brakes

Re: Techniques for braking on steep descents
I have ridden a loaded tandem + trailer down long Norwegian descents with only rim brakes.
What I do is
-alternate between front and rear braking and do it periodically instead of constantly or 'feathering' (so my speed can vary somewhat)
-never letting speed get too high
-I try to be aware of how the brakes feel & stop for a cool down if there is any change in the braking performance
-become a slow descender
Some people just stop periodically & feel the rims (or discs). You obviously have to be careful with this, as you can burn your fingers. Discs both get hotter and can withstand more heat

Re: Shoes for flat pedals
I don't find that many brands fit me well, so I am maybe not the best person to answer this.
But among the shoes that I've worn that work well for flat pedals are Timberland lightweight walking / trail running shoes, and Decathlon MTB shoes.
Decathlon's shoes have generally been good value for money for me. They have a couple of MTB shoes made for flats. Giro do some, too, though I haven't tried them.

Re: Severe lung issues and Indoor Cycling
I would honestly think that an exercise bike might be better than the turbo? They are a lot easier to get on & off, and easier to use, as well.
Just put it on a light exercise setting and pedal as long as he wants, or use a preset program. No faffing about with gears or turbo setup.
