@kersploosh@sh.itjust.works avatar

I think you're doing it right. The frame and derailleur both look like they are set up for top-pull cable routing. The manual you referenced is describing a bottom-pull setup, hence the confusion. You should only need to get the cable tension correct.

Yoooo that's hardcore 👏

What can't zip ties do?

aaaaace , in Need help routing the cable on my Shimano Deore XT front derailleur (FD-M739) [SOLVED]

Look on the underside of the crank housing. Is there a plastic track for the cable to go around and point up?

Operate the derailleur by hand to see which way it needs to be pulled, cable pills one way, spring pulls other way.

I'm not sure if I understand your question correctly, but here's what the cable fixing thingie looks like with and without the bolt.

Without the bolt, a vertical track for the cable to run through is visible left of the screw hole:

Operate the derailleur by hand to see which way it needs to be pulled, cable pills one way, spring pulls other way.

When I pull the derailleur to the right by hand, the cable bolt moves upward - this means it's a top pull, yeah?

https://lemmy.ml/pictrs/image/d8f25620-1ebd-4646-afe3-9064ed7597ef.gif

Does this all mean that just running the cable straight down to the left of the bolt (the way I have it) might actually be the correct configuration?

aaaaace ,

Try the lever with the cable taut.

So that sounds interesting, but the design looks like something that might be hazardous some people, especially when it's really hot out...

Stop dropping watt bombs on cliff faces.

I tend to prioritise the drivetrain for upgrades/maintenance, or go single speed ;)

Thorny_Insight OP ,

This hub was warning me about the impeding failure for a good year and a half and I kept ignoring it knowing full well that this day was coming. I knew I'd be able to ride back home anyway so I don't worry about it.

I'm the most atypical mountain biker you'll encounter and preventative maintenance isn't really my cup of tea. I ride it till it fails and then I replace it. I'm actually surprised my rear tire held up for longer than the hub. That thing is held together with duct tape and holy spirit.

Thorny_Insight OP , (edited ) in Some days it'll be like that

Overall the trip was a success. I don't let a minor setback bring me down!

toothpaste_sandwich ,

Well done! And what a great picture.

If there is a god, please give that man as much comfort as possible.

ClockworkOtter OP ,

A sentiment I can get behind

A decent stopgap could be to ship LiPo battery protection bags with every battery - they're comparatively cheap as hell and while they don't stop smoke (which was the issue in this case), they can greatly reduce fire spread and burn rates.

MindTraveller , (edited ) in Man who survived ebike fire that killed his family fights for change to UK law

The answer to people storing their ebikes in their houses and getting themselves killed isn't to ban ebikes or make ebikes harder to get. Because then they just drive a car and get someone else killed. The answer is parking minimums. We need secure, convenient, and electrified outdoor bike parking at every residence. It should be the law. If an ebike catches fire outside, nobody's going to die.

It would be a lot cheaper to stop allowing no brand cheap crap with no accountability to be drop shipped from China. There are clear and well defined safety standards for lithium batteries and they're just being ignored. They won't prevent 100% of failures but 99.9% if they're followed.

MindTraveller ,

I don't care about cheap, I care about preventing mass extinction. Bike parking minimums will make e-bikes feasible for a greater range of people and reduce car use.

Blackmist ,

If it doesn't have a valid CE marking all that shit should be turned back at the border. There's no excuse for deathtraps to be sold in first world countries.

It really doesn't cost much to make this stuff safe.

You know how easy it is to fake inspected stamps and certificates? That's SOP for these clowns. You sweet summer child.

Blackmist ,

I'm not talking about checking a stamp. I'm talking about a full inspections of an item taken at random from a batch. And charging them for it.

And unless you have an office in Europe where we can go and arrest you for fraud when it turns out not every batch follows the rules, it will happen to every batch as well.

NotMyOldRedditName ,

I imagine most of the batteries aren't LFP due to size restrictions on the bikes, but if the industry could move to that instead of pushing for even more range that'd be a huge boost in saftey

Nawww, let's blame the victims!!! 🙃

I really don't get people like that one dude. Someone makes a shitty battery and they turn around screaming yOuRe sTuPiD FoR ChArGiNg sUcH A DaNgErOuS ThInG In yOuR HoMe.

Can you imagine this poor dude? Lost his wife and two children. He's got to live with that. And the internet is screaming "you're stupid!!!"

Check please.

Choose LiFePO, it's way safer than LiPo.

I work at a bike shop. This is the main reason why we refuse to service cheap, direct to consumer bikes. Plus, most use non standard parts, underpowered brakes, etc. They're non serviceable death traps

I feel terrible for that guy. Sadly most consumers don't know. They see one bike that's $1200 while most are $4000+ and they think they're getting a deal

IGuessThisIsForNSFW ,

I moved into my local city and really want to pick up an e-bike so I can get around easier and don't have to drive. I was hoping to spend less than $2000, but stories and comment sections like this make me pause. What should an e-bike cost, and do you have any recommendations on reputable dealers? I'd really appreciate any information you might have.

negativeyoda ,

Get something mainstream. As long as the bike has one of the following engine systems: Shimano, Bosch, Specialized, Mahle, TQ and a couple others I can't think of off hand. Any of the other weird ones are often impossible to diagnose and work on

Bafang motors are a crap shoot. They make a couple that are okay, but also a lot of low end, sketchy systems.

Electra has a couple of cheaper models that come in under $2k. While the motors themselves aren't unsafe, I think the bikes themselves have underpowered brakes and the like. Something like the Specialized Globe is $2800 and is a pretty solid, utilitarian platform.

Avoid Rad Power, Lectric, Super 73, and any of the other weird, fly by night direct to consumer Asian brands

IGuessThisIsForNSFW ,

Thank you so much for this! I'll look into the companies that you listed and see what's what.

drmoose ,

I'm sorry but no sane individual should pay 4000$ for a bike. That's insane.

negativeyoda ,

If it's your interest, why not? People buy all sorts of stupid shit. At least my expensive, stupid shit keeps me in shape.

My road bike and mountain bikes aren't even top tier and both individually coast twice that. A new, tricked out Moots or SWorks is $15k.

A $4k eBike can replace your car and save tons more in the long run

Lithium battery fires are terrifying, there was one in January on the Toronto subway. Thank goodness they were able to evacuate everyone before it exploded, one of my classmates was on a different car when it happened and he said he heard the explosion as he was leaving the area.

I also learned that people apparently packed their laptops/iPads/portable consoles in their checked baggage, and I've never had peace of mind on a flight since that day.

There are three reasons you probably don't need to worry about those checked devices.

First, ebikes have way larger batteries than mobile electronics. The first laptop that came up when searching for laptops with large batteries had 80 Wh. The smallest ebike battery that appears in the first article searching for "ebike battery capacity" is 400 Wh.

Second, these problems tend to occur in uncertified third-party knock-offs. Your Lenovo or HP or Apple laptop, or even your Shimano or Bosch ebike, are much, much less likely to fail than a cheap eBay or Amazon battery.

Finally, and possibly most importantly, you are at highest risk while charging, slightly less risk while in use, and lowest risk when off. A device switched off in an aeroplane cabin is about as safe as it can be.
