This way you get the chainline right. One tooth more doesnt require adding any links to chain.
Its tough waiting for it to get there huh? ...
I ordered it with the lowest (-18%) available gear, yielding just under 61 gear inches. That puts it in the same rough range as the Strida (~56 gear inches), making the pair well matched for his-n-hers outings and ridable when we visit my family in the hilly bits of California.
Just a week in and...waiting..for..the...Brompton...is...agony.
(I have to keep reminding myself, when I
think I'm having a bad day, to remember the voyage of the Endurance.) Taking to the streets on the Strida takes my mind off the calendar...and the clock.
