I am on my third Garmin watch currently on a Fenix 6. They have all been extreme good and battery do not seem to degrade very fast at all. I find my 6 is all I need and no reason to upgrade. I would go with smaller size as had bigger before and does get in the way.
Have 3 rides and 50km of riding on my fixed dt swiss 350 rear hub and so far holding together. Defiantly engages differently than it use to. Not quite as smooth or as quick engagment maybe but still fine. Hope it stays together. Those Onyx hubs are expensive like $1000 Canadian.
Bike was brand new whatever grease that was in there was stock. Been on two big rides so far pushing bike hard and hub is holding up so far. I went with 24t.
I blew a dt-350 swiss hub on RM blizzard powerplay in 130km. Which is stock on bike. But found out later the problem was the grease was to thick and to much for winter use. The gears were not engaging all the way and just stripped the tips. You might want check how much grease you have in hubs...
I just found out why rear swiss 350 hub failed. It had too much grease in it and the wrong grease for cold conditions which I was riding bike in. Just the tips were engaging and had stripped the tips. So after I get new hub with lighter and less grease it should be good.
My weight 52 pounds Rocky Mountain Blizzard powerplay a50. That ARI if 42 pounds sounded amazing. I already blew my rear hub with 140km in 3 weeks. Which kinda sucks and it a good hub Swiss 350. These e-bike fatbike put huge strain on rear hubs.
