Installing rear wheel without dropping chain
Is there a technique that allows installing a rear wheel into a bike
with a rear derailleur that avoids dropping the chain? As the rear wheel is inserted, the chain is pulled by the cogs, which causes the front chain ring to spin backwards and, about half the time, drops the chain. Replacing the chain then makes a mess. Yeah, I could carry a glove, but ... -- Joe Riel |

But have you tried placing the chain on chainwheel #2 ahead of time (the smaller of 2 chainwheels or the middle one of 3 chainwheels), then jamming the front derailleur up against it by attempting an upshift while the cranks are stationary? I'm just speculating, but it seems that might hold it in place. -- - Frank Krygowski |

Yeah, I could carry a glove, but ... I guess(tm) that it could be solved by securing the chain to the chainwheel. I wire ties for most everything of the sort: http://g01.s.alicdn.com/kf/HTB1DKrLHpXXXXcMXVXXq6xXFXXXg/pvc-coated-garden-twist-tie-wire-in.jpg The local dollar store has these for ummm... $1.00. Secure the chain to the chainwheel at one point, and see if that helps. If replacing the rear wheel causes the chainwheel to rotate backwards, then I guess(tm) securing the chain near the bottom of the chainwheel would be best. When done, throw away the greasy wire tie. Disclaimer: I haven't tried this. No warranty expressed or implied. If it doesn't work, I'll deny ever having suggested it.

That's a different situation. The rider prevents the crank from turning backwards, so the chain doesn't come off. Doing this solo, I don't know an effective, simple way to prevent the crank from turning backwards. -- Joe Riel |

Two flats already this year, but both were in the garage, so cannot complain too much. -- Joe Riel |

But that doesn't alleviate the need to twist the oily derailer back away from the cassette. Which may be the reason that cyclists wear black shorts. The grease marks where you wipe your hands doesn't show :-) -- cheers, John B. |

But that doesn't alleviate the need to twist the oily derailer back away from the cassette. My bike has a "chain hitch" brazed on to the chain stay. You shift to the smallest sprocket at the rear before dropping the wheel out and the chain is "hitched". To re-install the rear wheel, push the body of the derailleur backward, move the wheel in so the chain is aligned with the smallest sprocket and lower the bike on to the wheel so that the chain is lifted from the "hitch" and the axle is positioned in the drop outs. No grease or oil on the fingers. Which may be the reason that cyclists wear black shorts. The grease marks where you wipe your hands doesn't show :-) My shorts are not black, and grass is usually available to wipe hands on if they become dirty. -- JS |

Pull back the RD when reinstalling the wheel. Lou |

The grease Those of us who use wax-based lubes don't have oily chains or derailleurs. My chains aren't perfectly clean, but if I do have to handle it, I usually end up with just a tiny smudge on my fingertips. -- - Frank Krygowski |
