Stripped cranks & isis hub
Florida- What hub and crank set are you using? Are they Aluminum cranks, like I am picturing? -- Here is my view on aluminum cranks - some facts, some speculation. They can be pretty solid and strong when made to be, tho you still have aluminum splines. Whenever you tighten the aluminum cranks onto your steel hub the aluminum fatigues first. The more you take them on and off the more mashing around you are doing to those (soft) aluminum splines. Now say you are out on a ride and your crank is a little bit loose, just enough you don't notice for a bit, or worse don't have a tool with you. Those aluminum splines are taking quite a beating and eventually the shape of the splines will be ever so slightly different from the shape of your hub. This is not a huge issue as the ISIS design is tapered so the cranks will just have to get tightened a micro amount further and it will be tight again. However without the original fit of those splines it is going to loosen up again much quicker this time. This will continue to happen more and more until they loosen every ride. The same thing can happen with steel cranks, but it is much more subtle and can be fixed by over tightening(in my case). I think everyone is pretty happy with the Moment cranks, tho I know there are a few out there that are starting to experience the downside to aluminum splines in general. The fact is for people who ride a lot and cant always get to their tool the exact moment they feel movement in there cranks are going to experience less than perfect results in the long run. Whether this a big issue to them or not is personal preference. -- agentQ '*)--SmallSpin-'O,*' (http://www.youtube.com/watch?v=IiFMXG116BE) '*)---TreFlip-'O,' (http://www.youtube.com/watch?v=zpT0YFDgmz4) '*)--DoubbleFlip-'O,*' (http://www.vimeo.com/683454) --- 'Uneed Films' (http://www.uneedfilms.com) ------------------------------------------------------------------------ agentQ's Profile: http://www.unicyclist.com/profile/13021 View this thread: http://www.unicyclist.com/thread/72336 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Giving tapered cranks a few good thumps with a hammer, before putting on the bolt, is a good idea. It distorts the two parts to have a much larger area of metal contact, otherwise, tiny high spots will hold the metals apart. Assembled with grease, they should stay on unless you need to change them. Properly installed, there is no movement or wear, no need to disassemble and re grease etc. Rotating cranks may help the rim last longer, so that you are not always dropping on the same spot. But a price will be paid in spline wear. The splines will last forever if it's put on right, and left there. -- feel the light ------------------------------------------------------------------------ feel the light's Profile: http://www.unicyclist.com/profile/14551 View this thread: http://www.unicyclist.com/thread/72336 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Stripped cranks & isis hub
Hey, I was riding recently when I noticed a slight click(not audible) on my left crank when riding, which I accounted to a messed up pedal. Later that day I broke my pedal and switched pedals and still found that I had a click on my left side. My friends dad told me that my click was from a stripped crank, which I found was true. So he then told me to rotate my cranks and that that should take care of the problem and it has taken care of the problem so far. My question for you is there anything else I should do to help aleviate this problem and keep it from reoccuring? -- Michaelgoround ------------------------------------------------------------------------ Michaelgoround's Profile: http://www.unicyclist.com/profile/17218 View this thread: http://www.unicyclist.com/thread/72336 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

I used the hammer approach and just smashed up the thread inside so I can no longer take it off with my crank extractor.

Ok, so my cranks still stripped(rotating only helped for awhile). Soooo.. is there anything short of shimming that I can do to fix it? Could I also get a link to a good tutorila on shimming? -- Michaelgoround ------------------------------------------------------------------------ Michaelgoround's Profile: http://www.unicyclist.com/profile/17218 View this thread: http://www.unicyclist.com/thread/72336 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

I've heard of putting solder between the gaps. I know nothing about it, so do some research, it might work. -- wickedbob R.I.P MITCH HEDBERG 'Add wickedbob to your ignore list' (http://tinyurl.com/3dfrko). Ducttape wrote: haha!

Is it possible to deflate my tire and rotate it while it is still on the wheel. I really dont feel like taking it off. Its so annoying. Everytime I take the tire off I scratch paint off the rim. -- Unicycle-Emele Any unicyclist in Westchester County, NY 'pm ' (http://tinyurl.com/6xu626)me.

Plastic will rip through a few coats of spray paint too. lol Its easy to deflate the wheel and twist the tire. Just hold the valve so the tube stays in place. Fill it up just a little bit so you can reposition the tube first, then pump it up to your usual pressure. -- Jerrick '*Bought it!*' (http://tinyurl.com/6ywusa) *Press Alt+F4 to fix post stretch.*[SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC][SIGPIC]JC~ ------------------------------------------------------------------------ Jerrick's Profile: http://www.unicyclist.com/profile/11632 View this thread: http://www.unicyclist.com/thread/72336 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |
