Yeah it’s kind of a bad route. In by the headtube, out below the DT water bottle and over the top of the BB, and then a bend down in to the chainstay.
Yeah, much more well behaved with the clutch off. I cleaned the bike today and with the clutch on if I rotate the cage towards the BB it doesn’t feel like a smooth rotation. It takes a lot of force and then pops loose. I’ve never serviced the clutch but it is clean and the cover is doing it’s job. If a dry clutch isn’t the root issue it’s certainly not helping.
If the trail starts getting steep quickly, within a few pedal strokes:
I’ll shift up the cassette 3-4 cogs
The chain & dangler will move up to the requested cogs
The chain drops back down to the cog I was originally in, or to a smaller one
The derailleur is in the position that I shifted it to, but the chain isn’t aligned anymore
Could be a sticky B pivot and sticky clutch, effectively creating a really excessive B gap. This is a FS bike so then if the swingarm moves it could be pulling/twisting the chain/derailleur in a weird way.
I want to put a rack/dynamo on the fixed. The fork is a soma with mid and dropout mounts. Something like the Lucas 3. Any thing similar worth checking out?
What does it do in the stand? When it’s not under load.
What is the shifter doing? Is it pulling cable correctly and the chain is just skating around on its own?
I have had like a years worth of shifting issues with one bike and it turned out to be too much tension on the clutch. It was a new derailleur, deore 12s, adjustment is under the cover. Removing some tension and it shifts perfectly.
My symptoms were not like yours though. My issue was that it did not want to shift into the higher gears, so it wouldn’t shift and i would keep pedaling then it would randomly jump two gears harder at an unpredictable time.
Mine struggles to shift in to higher gears as well. I’ve just got it set up with a little bit less than ideal cable tension so that it will shift down and I just push the lever a little further to get it to move into a bigger cog.
Have there been any advancements in minimal security pocket-sized locks? The only time I leave my bike is getting ice and a Coke from rural country stores which often have zero traffic and big windows; but I “lock” to the propane cage or whatever just in case.
