chain retention and 1×8, 1×9, etc.

[Lt. Dan]

I ran cobbled together 1x setups for a few years before my current bike which is a 1×11.. The Narrow Wide front chain ring with a proper length chain will have you covered on 1×8 and 1×9 setups. If you are running 10 speeds and higher, definitely spend the 40 bucks for a clutch derailleur. I LOVE not hearing the chain slap the stay going off jumps!!!

Dusting this thread off to ask about “direct mount” RDs.

Backstory is, I built up the 1×8 with a Paul Chain Keeper, it’s great but I think the 25 year old Suntour RD I pulled from my parts bin must have a pretty worn spring. The cable and housing is brand new, not hanging up on anything, but shifting to the smaller cogs is delayed by a second or two.

I’m going to replace the RD with a Shimano Deore 9-speed, but I see there are two options. One is “direct mount,” the other is the old style I’m familiar with. My bike has a non-replaceable hanger; it’s part of the frame. Which should I get and why? What is direct mount?

Direct Mount lops off part of the derailleur and is used on newer bikes that have this elongated piece on the dropout. Scan down this article to see a pic: https://www.pinkbike.com/news/Shimano-Officially-Introduces-Direct-Mount-Rear-Derailleurs.html

You want the standard one.
