I have the r8 on a triple 3x8 stock Btwin Triban 500. How do I fix the derailleur dropping the chain from the largest to smallest cog? No matter what cable tension, the front derailleur randomly jumps past the middle chainring down to the smallest. Any help is appreciated 👍
I have noticed, that your guide pulley is not on the same plane as the smallest cog. It is pretty obvious, that far side of the pulley points more towards the hub of the wheel by some degrees. Is it on purpose?
Very nice video! I have a question. I am planning on getting a Microshift acolyte 8 speed rear derailleur. I have a 1 speed crankset and a 8 speed shimano 11-34T cassette that has a capacity of 23. If the Microshift derailleur has a capacity of 41T, what would happen if I used it with a cassette with only 23T? In other words, I cant go past that capacity but is there a possibility of going too low?
It's ok to go lower in terms of capacity, but you will run into problems with the minimum cog size of the derailleur. Acolyte is designed for a 42-46t max cog, so if you run a 34t it will shift very poorly. This is because the guide pulley is too far from the cassette.
Just the way the derailleur mounts. Most bikes have a derailleur hanger so you can mount the derailleur directly to that. Some don't so you need a hook on the derailleur that can be fit under the axle nut on the rear wheel.
Tough to diagnose on RU-vid, but I would first make sure you have a model that is friction transferable. We do make some bar end shifters that are not transferable. For more sophisticated service, I would submit a service claim on our website.
@@microSHIFTTECH thanks for the quick response! i managed to fix it by disconnecting the shifter cable from the rear derailleur and turning the dial really hard. it seems like it was stuck for some reason. i had been using it for a few months on indexed mode prior, but wanted to go into friction since i'm using a 7-speed cassette with an 8-speed shifter and it was giving me some issues with my top two gears.
