Beautiful late November day here in Colorado. This trail was not technical and therefore was a good opportunity to exercise the Hydra at some higher speeds and test out the drivetrain modifications. It’s still not quite right but a huge improvement over the original skipping issues so will take...

150mm is just too short IMHO. 160mm seems to be the sweet spot. There was a pretty good review of crank length comparisons and ps vs cadence feel. They came to the 160mm being the right comparison.

Good luck with that. Glad you are getting some input directly from WW.

fun fact: I charge my battery to 85% using the Grin Satiator and that’s 56.6v. 👍

Ok… it’s done for now. Flipped the chainring to the outside of the spider which definitely helps with the chain stay rub. Spacers to retain the chain guard. Sort of by accident ended up replacing the bafang 44t chainring with the Wolftooth 44t which is a lot lighter - not that it matters...

Some good progress today. Adjusted everything including the ‘b screw’ and got a much better wrap. Test ride was good - had to work very hard to get a slip in the smallest cog. Considering my tuning skills are poor and there is improvement to come there, big step forward.

Yea, I have a lot of adjustment to do. Just glad even just ‘slapping it on’ has made things more positive. Really the first time I’ve ever touched a derailleur so working through it. Appreciate the good work you and @TDA78 have put into fixing this issue on the Hydra. Ibera Easy Utility Bicycle...

Quick update. Decided to install the Garbaruk cage and pulley system just to see impact. I still need to do a lot of adjustments to the derailleur but snuck a quick test ride in and seemed promising. 20 - 24mph with just a skip here or there. Looking forward to getting it dialed in.

That’s amazing news @kwseattle! Just becuse I have to hear it, you are using the 11t cog at speed without any skipping? Would you remind me on how much you pushed the front chain ring out again? I’m sitting on the Garbaruk cage and pulleys and the M8100 has arrived as well. Two options to test.

18 - 20mph is a speed we all need with out skipping and jerking - I’ll do plenty of riding on street and path as well as trail, and agree on the challenge of pedaling on the 15 cog - it’s not enough. I’m sure we will find a solution, in time - spiders, derailleurs, maybe sacrifice a goat…

Same here Brother! The motor is great but the drivetrain issue is unbearable for me. I’ve got the Garbaruk cage and pulley system in but think it is less likely to solve anything than the M8100 inbound. Good thing I’m excited about the emtb thing in general, because otherwise I wouldn’t be so...

FYI… 85% charge for me is 56.6V

I have the 500c and believe it has been displaying battery voltage normally for the few weeks I’ve been using it.

I’m just thinking circle size might have an effect on how the chain wraps. Looking forward to seeing the 8100 installed and it’s impact.

And did the 44t experience the same log cog chain skip the the new bikes have?

@loamoaf yes, for me ‘the Green Goblin’ 😉 Do you think the Garbaruk will fit the M8100 as well?

Bling…

Uh huh :rolleyes: Now you tell me!

Thanks @loamoaf , I'm right there with you: it looks like the 8100 will be the best solution and I will return the Garbaruk unless I am overwhelmed by the bling factor of the G lol
