Stronger rubber cement?
On road bikes it usually happens when hitting a rock "just so". Like when the rock gets under the tire off center and flies off to the side with gusto. Haha and makes a loud CRACK as it hits the passenger door or window of the car to your left :-) |

Also, drivers give me extra wide margin when I just came off a dirt path in bad weather and all sorts of gunk flies off my rear wheel. -- Regards, Joerg http://www.analogconsultants.com/ |

No, sometimes they damage the side wall of my tire. Depends on the shape of the rock and how it flips while rolling over it. Just ordered a CST Conquistare 700c*25 for a test. We shall see how that holds up. -- Regards, Joerg http://www.analogconsultants.com/ |

Also, drivers give me extra wide margin when I just came off a dirt path in bad weather and all sorts of gunk flies off my rear wheel. I am beginning to wonder. You have repeatedly stated that your usual speed is 20 MPH. Now, a 26 x 3.0 tire will be spinning at about 250 RPM at that speed..... But this speeding tire accumulates "all kind of gunk"? I ask as my road bike, who's wheels are spinning at only about 157 RPM don't seem to accumulate any junk at all. -- Cheers, John B. |

I don't believe it. -- Cheers, John B. |

Soil chemistry n geology relevant to cycling...exposed parts, proximity. Check your soil type prob with U State Ag ...
I doahn have wet cycling experience on Cal ( !#@ ) yet getting the film with diesel fuel mist off muh winshield is a trip to the car wash with .... water contaminated with Cal soil. https://en.m.wikipedia.org/wiki/Alkali_soil Morter or moretar ... on the west side where ground is raised sea bottom. I did drive up out of Coal banks at the Missouri n across the farmlands above after rain. The place is a huge mud dune. $20 at the car wash removing MUD .... the truck wudda understeer ed off the interstate with that mud load. |

You have repeatedly stated that your usual speed is 20 MPH. Now, a 26 x 3.0 tire will be spinning at about 250 RPM at that speed..... But this speeding tire accumulates "all kind of gunk"? As explained many times 20mph is the speed on flat sections of trail or slightly higher when downsloping a little. My average trail speed is more around 10-12mph depending on turf unless I want to push it. Meaning there are murky or gnarly stretches in the low single digit mph. There are people on this NG who do not understand the difference between top speed and average speed. On such trails I often slow down to enjoy the scenery, animals, and so on. Something that the "bicycles belong on road" people will likely never understand. Then I ride on 29" wheels. A usual scenario is that I come back on singletrack from Placerville and the last section before entering a regular road is this: http://www.analogconsultants.com/ng/bike/Chapparal2.jpg Imagine that after three days of rain. Also, on rainy days my average speed on the "real" trail can drop substantially because the rear wheel becomes stuck several times. Big clump of mud caked up near the BB, wheel will hardly turn even in granny gear, have to stop, look around for a sturdy branch piece of manzanita, poke the mud out of there, continue the ride. Until it gets stuck again a few miles later. Sometimes it's so bad that I strap that piece of manzanita onto the rack. I ask as my road bike, who's wheels are spinning at only about 157 RPM don't seem to accumulate any junk at all. Well, do your road bike tires have knobbies? BTW, my road bike does fling dirt off the wheels after a muddy stretch of "bush road" and I have caked up its BB area with mud. Usually purposely rolling through some water puddles washes the mud off the tires, something that does not work for the MTB tires. -- Regards, Joerg http://www.analogconsultants.com/ |
