getting proper chain length (who uses half links?)
finally finished getting everything set up on my first conversion attempt. i put on a 42t chainring and 16t cog, bust out a new sram pc58 chain and find out that it doesn't fit. the bike is an 80's pinarello with horizontal dropouts, but they're the later medium length kinda ones, not the older really long dropouts.turns out the links come up just a bit short with the wheel all the way forward, but if i add a link i don't have enough room to get proper tension. i assume this would be a situation remedied by a half link. i've never used one, is there any downside to having to employ one?
i pulled the 42t chainring and put on a 48t i had, added a couple links, and behold it happened to be just right. 48x16 is ok but i like spinning it a bit more. i guess it's a matter of finding ring/cog combo's that'll fit? and/or just getting a halflink to help accomodate ring/cog combo's that fall in between?
nothing's easy.
