I replaced the chain in my Vado after 1 year and nearly 2,000 miles ridden. The chain was so stretched (1%) that it damaged two smallest cogs in the cassette.I am at 4100 miles on mine and I ride on paved and dirt roads. I had no idea. I'll haul it over in the spring for a tuneup and ask the guys about it. I do clean and lube the chain often.
There are other chains on the KMC website. I wasn't sure which type you need. I have a 10 spd cassette and use this one for $49:Hey 6ZF, that link takes me to a DLC12 chain that costs $140!!!! It must be made from the same gold used in Trump's toilet.
Or is there another chain that works? Like the E9 for only $50.
And Cow, did you do 4100 miles on 1 chain?
@Rome, that chain is a road bike race day chain. The side plates are see-through to reduce weight. It is not very strong. An X-Bridge would be much better. Yes, Kilowatt bikes will Kill-o-whatever drivetrain you install. Nine-speeds are robust and can still have a good range of gear selections. I would rather change a chain before I 'need' to, just like I would rather change my shorts before I 'need' to. Changing under cloths before you absolutely have to may be uneconomic but it makes life better. Just like changing the oil in a car on a advanced maintenance schedule.First time owner of Bafang 620, I have already replaced chain at 700 miles not out of necessity but for looks.
I hope I don't have to replaced cassette to often but I guess that's expected with these motors.
I use the same motor, but it's too new for me to be able to say about wear. But $90 for 2k seems a bit punishing re maintenance.So I have a Bafang mid drive 1000 watt motor on my Specialized Crosstrail. I replaced the chain last year when I did the conversion and then replaced the chain and cassette ($90) about 5 months ago and now the bike tech said it needs both again. He showed me the stretch and how the gears are getting chewed up. He says he's seen lots of these issues lately with the bigger motors. The conversion only has 1800 miles and I'm kinda wondering if this is going to be an expensive continuing problem. Are you guys seeing this? And is there a stronger less stretchy chain?
FWIW My bike guy is really cool and doesn't charge me most times for things like gear adjustment. So I bring a six pack of craft beer for his trouble.
