Yeah, I could carry a glove, but ... I guess I've never worried about it. I'm usually able to get the chain to re-mount itself by turning the cranks and upshifting the front derailleur. 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. That might work. I'll try it next time. Two flats already this year, but both were in the garage, so cannot complain too much. Two flats in four or five days? Yow! If that average continues, you're allowed to complain! -- - Frank Krygowski |

Yeah, I could carry a glove, but ... Probably not. But there are bikes that have a "chain hitch", a small lug brazed on the R.H. Seat Tube that holds the top run of the chain up above the cassette. 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. Your derailer must be very, very clean. 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. Interesting.

Try a stick, small tree branch, or hooked coat hanger wire to manipulate the chain. Your hands need never touch whatever concoction you use to lube the chain. I keep a few sheets of towel paper in my junk bag. Also, a 35mm film can with shaved soap and borax powder for hand cleaning. Somehow, I always seem to run out of towel paper. Hint: Don't blow nose in towel paper after using it to wipe crud off the chain. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
