Why is it such a sin to use the rear brake
#51
When braking hard, not necessarily a panic stop, I apply both brakes until the back tire starts skidding. Then back off the back brake. Never had any problems with the technique. Unless I'm in a turn, the road is wet or some other condition causing problems.
I can only remember having 3 "cartwheels" in my biking life. That's not counting meetings with autos, side slipping in the corner, etc.
The first at 12 yrs, I was riding down a steep bumpy path in a quarry. Too steep. I never touched the brakes. But I hit something! Never knew what.
The second at 19 yrs another quarry, we were using a steep downslope and a small berm to do jumps on our 10spds. The other kids were jumping higher than me! So I pedalled down hard hit the berm and really flew! Mid air the bike rotated forward and we landed in a face down position.
The last time at 20yrs, riding a borrowed bike, the brake lever fell off into the front wheel still hanging by the cable. I was in a hurry so I continued pedalling, leaned way over the front tire, pulling on the cable, cursing all the while. The lever slipped crossways into the spokes. The front tire stopped spinning. I managed to stop the bike by applying my face to the sidewalk.

I didn't use any brakes on my ride to work this morning. Just thought I'd throw that out there.

Lots of diverse topics in this thread!
1. Trolls happen, nothing you can do to prevent them, just try not to encourage them.
2. I do wear socks with my SPD sandals (okay, I have really ugly feet).
3. I do have a kickstand on my commuter bike (DaHon Curve -SL-8) but have never noticed any side drag, etc.
4. I use both brakes but favor the front.

In an emergency stop you weight shifts forward and therefore lifting weight of your back wheel. When you brake with your rear brakes you only get a skidding back wheel and no stopping power. On a shortwheel based recumbent bike its even worse with all the weight on the front wheel you have almost no stopping power at the back wheel at all.
Your recumbent example is a special case, however. For regular bikes and longer wheelbase recumbents, the rear brake's contributions aren't zero until the rear wheel lifts off the ground. Even in your short wheelbase example, the contribution from the rear brake isn't zero. The time between going from contributing some deceleration to contributing zero may be shorter but that's a function of the bike geometry.
When in slippery conditions the rear brake can be usefull as well as when going downhill. You can then use the front and rear brake at the some time or switch between them to let them cool down.
You can also use the rearbrake to slowdown a little bit but not for coming to a complete stop.

On downhills...high speed downhills with a 50 lb touring load in mountainous terrain...I've never experienced wheel overheating because I don't drag my brakes. You will get far less wheel heating if you use both brakes to check your speed momentarily, then get off the brakes entirely. Simply sitting up can have a dramatic effect on speed too.
And a skidding rear wheel doesn't necessarily mean that you are going to crash. Again, ask the 10 year old.

Hmm, I use both brakes, but I have my front brake adjusted so that I can hit it as hard as I want to and I won't do an endo unless I move my body weight forward slightly.
But, I have the Burley 99.9% of the time, so I have to use both brakes or the rear brake will just wear out right away and only cause me to skid. Plus, I don't think I can do an endo with the trailer attached, but anything is possible, I s'pose.
