I shouldn't be putting a lot of $$ in them.... As long as original equipment is working good.... We wouldn't be able to take advantage of it anyway....
As far as I can tell, other than a new axle system on my front wheel, and ball bearings for wheels & Crank, and new BB Pulleys in the derailleurs on both bikes, That, and a nice cleaning is all that is 'planned' during the winter months.
10-15 years ago I put new rims, and new headset bearings on my bike, and I did new tires and pedal, chain & Derailleur re-lube on both bikes this year...
I'm debating on attempting to fix a slight contact spot on one rim of Gitane.. but I think that will depend on how stir crazy I get later on this winter... It's minor...
I do have one issue I'm concerned over...
Gitane has Cottered Crank...
I may attempt removal, but if Cotter Pins don't "give", I may just back off the adjustment side of crank, squirt in some fresh grease, and call it a day, as it turns smoothly now with no play....
Regarding the pictures I posted.... and vintage of the bikes...
It could be that the Peugeot is a U09, but catalogs then place it at 1978 which pre-dates the decals...
Gitane is a Mixte and catalogs that show this seem to be 1968, but don't have green as a color. If the serial number on frame means anything, it may point at 1968 as it is stamped: 8 1290
But, they work... so: What, Me Worry?
!
Thanks for any input...
