19t chainring.
 

the last time i made myself a 20t chainring.
that was last year.

a few days ago. i went beyond 20t.
i 'made' a 19t.
it started when a friend offered a sugino impel 42-32-22 for just $17 brand new!!
as some of you may know, it is an old set. bcd 94/58. 5spider.

the sugino impel crankset that i got, came with 42-32-22t chainring.
i was already aware of that another version comes with 42-32-20t.

then I started to source for some 20t cogs.
to no avail.
then I found a 19t cog with six holes, that was supposed to be used by fixed gear riders.
drilled 5 holes with a bcd of 58mm
and voila!
now i have a crankset of 42-32-19.
