Rear Derailleur = Yes. Mid-cage as stated in original post.
My fear is that I’m offering too-much slack. I only have one quick link. I’ll probably mock it up with RD at current length before snapping the quick link in place. On Jan 20, 2024, at 2:21 PM, Patrick Moore <bertin...@gmail.com> wrote:
Forgot to add: the big/big method is a way of getting the chain length correct for a given derailleur. For a derailleurless drivetrain you want all but very minimum slack removed. You want to use the big/big method with derailleur attached, leaving the derailleur stretched but not to near seizing or breaking. A half-link's leeway is no big deal since you'll have a derailleur.
Or are you planning a derailleurless multicog bike? (I doubt it but serious question.)
Hi all,
Rear: 11-36, front: 46-34-22
I'm using the big-big chain sizing method recommended by many. Of course though when pulling most of the slack, my master link lines up with an outer link. So instead of adding one link [outer+inner] from the match point to get my cut point, It's suggested to add [inner+outer+inner] and the chain is looking droopy as hell. Rest assured I will never be in a big-big situation, ever. My rear derailleur is mid-cage so I'm worried it won't pick up all the slack I'm affording the chain in scenario 1. I mocked up a 34F to 11R situation, which I do end up in on mellow downhills, and it looked crazy loose.
I cut the chain leaving myself the option to cut again, and took photos. First pic is as recommended by park tool youtube, pull to nearest inner link, add one extra. Super droopy.
Second pic is mock up of what chain slack would look like if I cut one more [inner+outer] link out. Still has slack, feels like it wouldn't be a problem in any normal gearing.
RD arrives in the mail today. If this exercise is foolish until I have the RD installed, I can be patient. Just curious if anyone has made the judgement call to only add .5 links instead of 1 full link.
