riding in ths rain
sp4rky-m4rky wrote: nothing to do with riding in the rain but I didnt want to make another thread, A friend who rides trials bikes said the reason that they drill rims is not to save weight but to reduce the risk of snake bites, I cant remember the reason he said because he didnt remember what he was told but I think he said something about it help equalise pressure. I thought this sounded wrong and still believe the reason its done is to reduce weight, can someone clarafy? so does anyone know the correct reason/reasons for drilling rims? -- sp4rky-m4rky you may be lucky but you make your own luck *)--360--O* The Unispin Elite )---'O, Crankflip ------------------------------------------------------------------------ sp4rky-m4rky's Profile: http://www.unicyclist.com/profile/14270 View this thread: http://www.unicyclist.com/thread/60499 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- ** SPEED ** RETENTION ** COMPLETION ** ANONYMITY ** ---------------------------------------------------------- http://www.usenet.com |

riding in ths rain
I ride bike trials and i think that it may equalise pressure as the holes provide somewhere for the inner tube to go into when high pressures are reached, but i always thort it was weight loss... wow.. thats a really amazing fact.. that they might do it to avoid snakebites.. but to be honest on all the trials forums ive been on ive never heard that before. -- matti_marron ------------------------------------------------------------------------ matti_marron's Profile: http://www.unicyclist.com/profile/14815 View this thread: http://www.unicyclist.com/thread/60499 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- ** SPEED ** RETENTION ** COMPLETION ** ANONYMITY ** ---------------------------------------------------------- http://www.usenet.com |

If the tube could bulge out through drilled holes it would puncture more easily on the edges of the holes and would actually make snakebites more common as the air would bulge out of the holes instead of stopping the tyre hitting the rim in the first place.

My money is still on weight reduction. that is exactly what I was thinking (which is why I was asking) if you have your tyre realy hard you wont get a snakebite but if you lower it so it bottom out you run the risk of your tube being pinched, if your tube is allowed to bulge lowering the pressure inside your tube even more (although I dont think it will lower the pressure much atall) I think it will make it more likly to snake bite. it was a friend who rides trials bikes which may exsplain it if its wrong but he did hear it from one of the riders from the national bike trials when they drill rims they drill through both walls of the rim then put a tough rim tape around it so that the tube dosnt bulge right out -- sp4rky-m4rky you may be lucky but you make your own luck *)--360--O* The Unispin Elite )---'O, Crankflip ------------------------------------------------------------------------ sp4rky-m4rky's Profile: http://www.unicyclist.com/profile/14270 View this thread: http://www.unicyclist.com/thread/60499 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- ** SPEED ** RETENTION ** COMPLETION ** ANONYMITY ** ---------------------------------------------------------- http://www.usenet.com |
