101 Thinner cogs have the wear concentrated on a smaller surface..
A full bushing chain has a separately treated tube, pressed in , a current derailleur chain the half bush
it's a flange punched out when the hole was made .. out of that steel.
then the contact surface is the inside outer edges of the Roller,
rather than the whole width of roller and Bushing around the Pin.
Fully enclosed chain cases can fall under the it may need some oil and its let go bone dry
but Sight unseen... who cares .. its Just a F-ing Bike .. suit and tie , talk on the phone all the time..
fill the tires with straw ,like done when The Nazis occupied Benelux.
