The death of rim brakes?

I cannot believe rim brakes are going to be gone but maybe I am just kidding myself. I frankly hate the disc brake look and certainly for a long time parts will be around but are these rim brakes a dead deal. Deacon Mark One of my issues is that I realize we will have rim brake bikes for awhile but I just hope to keep the nice looks and basic set up. If it is not broke don't fix the puppy. The one item I have never experience is the idea on a long descend you can blow a tube. In the flatlands that to me seems impossible. To blow a tube on a long descend does the speed have to be really fast like about 40mph or say at 25mph for a long time. The biggest descend I have done is about 7% grade total for about a mile and the last say 1/4 mile is got to 9%. I could easily feather the brakes to avoid heat but maybe my experience is really limited for true mountain riding. Can you just pull the brakes up pretty good to get to a speed that is comfortable. In my case this descend got me to about 43mph my top speed for sure. Had the it been longer I don't know long I could have continued before I got to damn scared. Confession of the deacon in lent Deacon Mark It’s dragging brakes that does it, not personally had it and have more experience of seeing lorries with burning brakes for the same reason, around the area I grew up that has some steep and reasonably long hills, as kids the main road though the village passing over it via a footbridge you’d see lorries either in the sandpit on fire or driving past smoking. I’ve ridden down 0.5-22 mile hills on rims and discs, shorter sharper braking is generally better, and smooth! Is the trick to being quick and safe. Roger Merriman I agree but I also know that since I had that tire blow completely off of the rim the other day, that you always have to have tires you have complete faith in. There most definitely was some sort of damage to the bead on that tire. Since it really wasn't a tubeless tire we can expect that the loadings on clinches is quite a bit different than on a tubeless but I think that I will have to have a great deal of experience with tubeless tires before I have sufficient faith in them to do the 40-50 mph descents I was doing with clinchers in order to avoid using the brakes and overheating the rims. As to disks taking over - I don't believe that will ever occur. If for no other reason than rim brakes can be aerodynamically invisible whereas disks cannot be. |
