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!

Turn the bike upside-down.

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. Right there in the center of the city?

Not really, but certainly not covered in filth.

Melbourne has a lot of park land, but I don't live there. I don't even
live in the same state anymore.

My Mouton has a chain hanger. I never use it. Getting the
chain on the hanger seems nearly as messy as putting a
dropped chain back on the chain ring.

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.
