New to the post I would appreciate some help.
Installed the group set but I am having difficulty with the fine tuning. I am able to set the first gear (smaller cog) with minimal friction using the initial set up with arrow adjustment. I am also able to shift through all 12 cogs, but I find starting with the second gear noise in some of the cogs. When I try to use the fine tuning function using the App only it appears that I get no adjustment movement from derailleur. Am I missing something in the procedure of using the fine tuning? for example do I need to use the shifters in combination with the app fine adjustment set up? Or it is just simply the fine tuning function not working.
Would appreciate advise, thanks
After spending endless hours figuring out how to get all of my Wheeltop systems gears to shift smoothly, this is the process I follow these days.
1. Perform an initial 1gear to derailleur cage alignment.
2. Adjust the "B" screw position so that you can easily/smoothly shift up and down between the 2gear and the 1gear.
3. If it isn't shifting smoothly, I further adjust the initial 1-gear position, then slightly adjust the "B" screw again and again until the 2gear to 1gear and 1 gear to 2gear shift perfectly.
4. I downshift to the lowest cassette cog and tune the lowest cog so that it shifts smoothly between the lowest cog and the next lowest (12gear to 11gear and 11 gear back up onto the 12 gear) -
Double checking and being sure that the limit screw is not keeping the derailleur from shifting all the way onto the lowest gear
5. Then I make sure that the derailleur cage isn't too close or far away from the lowest cog and that these gears shift up and down smoothly. If it doesn't shift perfect between the 12gear and 11gear, I play with the "B" screw until its shifts perfect.
6. Next, I shift all the way back down to the 1gear and test to see if it still shifts smoothly in the 1gear to 2 gear, back and forth. (Then I tweek the "B" screw some more, until the derailleur shifts perfect on both ends of the cassette.
7. I start shifting one-by-one across all of the cogs, up and down, and perform my individual fine tuning of each gear.
Al least for me, this iteration process has let me get almost perfect and silent shifting.
One other thing I discovered on several of my OX derailleurs is that the relative position/distance of my 1gear (10-tooth cog) to the outside flat surface that the derailleur mounts on varies between bikes. I experimented with the initial 1gear calibration setting to discover that I was reaching the App adjustment limit of the derailleur and that there can be a shifting "dead zone" between trying adjust the step count number required to shift from the 1gear to the 2gear. I could always shift out of the 1gear to the 2gear, but could never shift back into the 1gear from the 2gear. I ended up installing a 2mm wide washer between the hanger and derailleur bolt, readjusted the initial 1gear calibration, and all of my shifting problems went away. (I did not have this issue setting up my TX system.)
