Linkglide lg400 cassette is no good???

[Ps71]

Has anyone noticed the wear on the freehub body with this cassette, i have one dt swiss h1900 wheel with a steel freehub and e thirteen espec wheel.
After just 70km on the e thirteen it has groves in the splines and even the steel hub on the dt swiss has small grooves after 230km, looking at the cassette there is plastic and metal that takes up the load on the splines and i dont think that is good enough on a ebike.
Never had this problem with other types of cassette
I have bougth the LG700 cassette because this has a aluminum spider without any plastic so it will not be so hard on the splines. Will put a picture here when i get it.

Ethirteen hub after 70km Dt swiss hub after 230km LG 400

This looks way better LG700

Just saw this thread or I would have taken pics of my hub body. I have a Gen II Trek Rail 7 that I bought in January of this year. I immediately swapped the 12-spd OEM SRAM drivetrain with the Shimano Cues 9-spd setup I'd been running on my home built 2003 SC Bullit with a Bafang mid-drive. I think one generally only needs 9-spd on a full power emtb, but that's a debate for another time.

Anyway, I just replaced the Trek Bontrager OEM wheel with a Bontrager carbon Line Pro 30 TLR 29'er that was on sale...straight pull spokes, carbon rim, etc. The OEM wheel is a Line Pro also but J-Bend spokes and aluminum rim. The hubs, other than the straight pull spokes, seem to be identical internally, and for sure the hub body swap to run Shimano 9-11 speed drivetrains are identical.

There was nothing wrong with the OEM wheel, but I know over time that I tend to trash J-Bend spoke wheels in gnarly terrain with aggressive riding...rocks, ledges, etc. So I picked up this upgraded Bontrager wheel. On the OEM wheel with its alloy hub body running an LG400, 11-36 cog, Cues cassette, I disassembled the OEM hub body to clean up and lube the internal pawls so I'd have a spare wheel. I saw only the minimal evidence of contact surface marks like you normally see on a hub body, but nothing like you're experiencing in your pic.

I wish I'd taken a pic of my OEM wheel's hub body, but I didn't know this thread would pop up...and I'm not going to break it down now to take a pic...LOL! DT hubs are pretty darned good quality from my experience, and the fact that your setup is steel makes it even more interesting. I installed my new Shimano adapter hub body on the new wheel just yesterday, so this is still fresh in my mind. It's an alloy hub body supplied by Trek/Bontrager, but I don't really know who manufactured it...but I doubt it can be any more quality than a steel DT hub body.

The pics of the inner contact teeth of the two cassettes pictured above show a dramatic difference. My new CS-LG400-9 Shimano Cues cassette that I installed looks more like Ps71's pic. I wonder if different LG400 cassettes manufactured at different times or in different manufacturing runs account for that. Don't know. The first pic looks like a rabid beaver cut those teeth. Still even then, I'd think a steel DT hub would stand up to that much better. We're saying steel, but I think most know all steel isn't created equal.

Interesting. I have the 10 speed lg300 cassette and did notice some indents on the steel freehub when changing a broken wheel last week. Not enough to concern me though.
That lg700 does look to be a better design, but twice the price.

Edit is that definitely steel? I thought the steel ones where all silver.

 

[Ps71]

The first picture in the first post is the ethirteen alloy after just 70km and the second picture is the dt swiss steel after 230km, both with marks in them but the dt swiss holds up mutch better.
Dont know if the design is different on other linkglide/cues cassettes but the way the LG400 is produced is going to cause a lot of wear on the freehub and i am sticking to the LG700 from now on.

The first picture is the ethirteen alloy and the second is the dt swiss steel, all the steel ones i used have been black

Bringing back this topic, is this really an issue ? Maybe someone running a CUES LG400 cassette could report ?

I don't think the LG400 cassette will eat the body like it was aluminum, but definitely could do some small indents like the pictures above.

 

[kaaskopf]

running the lg400 10 speed on my eeb, been fine for the last 400km
its important for emtb to have steel driver.
i run a lot of cheap aliexpress casettes before and never had any marks on steel freehubs.

i noticed the lg400 says 40nm on the lockring...
you know how much you putting on that lockring? 40nm is a lot! might have something todo with it...

 

[cozzy]

I swapped my lg300 today after a year. Mileage unknown, i don't track it.
Dt350 with steel freehub.
Pretty minor indents. Can barely feel them.

 

[kaaskopf]

looks normal to me. it says 40nm on the lockring on mine
maybe not tight enough allowing it to move and make those bigger indentations

 

[Astro66]

40nm is quite a bit of force. Really difficult to judge without a 40nm torque wrench, as it feels very tight.

I bought a Shimano Hub with a steel freehub. I just fitted the CS-LG400-11 (11-50T) cassette. Interesting to see if I get better wear.

 

[Spin]

This is the condition of my Hope pro 5 steel freehub after around 1000kms of use with an LG400 cassette.

 

[kaaskopf]

was it tight enough ?

 

[Spin]

Yes.
I don't think this is caused by inadequate lockring torque (although I can understand if it was loose) , I believe it's just load from the motor and possibly pedal kickback contributes also.

 

[PeteVC]

Hi I work as a bike mech.
I just logged into this forum to tell you that any (also non e-bike) hubs looks like this after some miles and some solid legs.
Its not a Torque issue.
My Pro5 on my Fran is shredded deep bc I kick like a horse.
Its brag dents.
Just imagine a Wrench of a 50 T sprocket length and standing (or kicking) with your leg on that wrench on such a narrow metal blade.
Yes...

So all good and in order.

Cheers

Its not brag dents its bad engineering

 

[PeteVC]

Its not brag dents its bad engineering

Yeah call the president to force EVERY Hub manufacturer and Cassette manufacturer ever to change it because you saw it for the first time and do not like it.
Who are you?

 

[Ps71]

Using the lg700 all season and no dents in the hubs, just no reason to use the the lg400 when it is a poor design.

 

[Spin]

Give me the durability of steel cogs mounted on an aluminium carrier any day! That's why I used to buy Sunshine cassettes from Ali.
Nobody has found a way to get the smallest cogs onto the spider though.

Unless you specifically want 10 speed. I did as its half the price and i prefer the short cage linkglide deore mech.

That would be a good reason

Who am i who are you ?
Its bad design and engineering its designed to fail Like so many other bike components but its ok because as consumers we are just meant to accept it ,
Do you have shares in the hub company as your defensive reply would make it seem so or are you just happy putting up with crap components because that's how there made so it must be right .

And Judging by your entrance into this forum you know it all anyway so there's no point talking to you as you must be right being a bike mech and all that and everyone who challenges you must be wrong
So all in all if you think that its acceptable damage that's great for you i personally don't
And as for your comment "Brag dents" what a load of crap is that what you tell your customers .

I have been a bike mech for a while and also all my colleagues know that this is just a plain basic fact that occurs in many Hub/Cassette interactions and is not something to worry or complain about.

That includes Bike Mechanic Masters who had their Shops with many Mechanics under them for 30 Years.
Sure you can decide not to believe actual professional experts in the field,since this seems to be the recent american style to go about things... but the nice part about mechanics is that the machine does not care about your delusions and gladly will serve much harsher lessons than I ever could. So please go ahead.

Its like complaining that Pads or Rotors wear, shure you can do it and claim bad engineering, but that just makes you look like a complete rookie and if you insist you know it better a fool ontop.

Why cant you just accept a basic fact of a field you are obviously new to and learn what is generously taught by actual (german) professionals instead of behaving like such an agressive dunce?

The part about brag dents was obviously a joke to liven up the discussion.

You don't seem to grasp the Fact that with better design and engineering of these items you would not have these issues period
You seem to be mixing up wearing items also with an item that should not wear especially in the way it does wear
You cant compare a set of brake pads and rotors to this wear on a freewheel hub, that's just grasping at straws to try and make a point as the two items shouldn't even be compared as one is designed to wear the other is certainly not or at least shouldn't be ,
So you sir are the rookie and as you don't also know my background i suggest you keep the rookie , fool and dunce comments to your self as the only rookie and fool here is you arguing that the wear presented on these items i.e. the freewheel to cassette interface could not be eliminated with better design and engineering
And as for your I'm a German comment your ego does seem to be getting the better of you in this instance if you cant grasp the simple fact that its a design and engineering failure i guess you should sit down and have a good hard look at the items in question and the wear presented and may be you might learn something ..

 

[Astro66]

Its like complaining that Pads or Rotors wear,

Pete.

All pads and rotors wear. That's because all pads and rotors are designed to wear. Almost no other cassettes create wear marks in the HG freehub bodies like the ones created by the CS-LG400-11 cassette. That's because they are not supposed to create wear like that.

If you cannot understand that. Then I suggest you take this discussion no further. You are not covering yourself in glory.

Whilst I wouldn't be concerned about those wear marks, because I change my hubs regularly, rather than do extensive maintenance. Some people do keep their hubs long term, by maintaining them, and those wear marks would eventually create movement between the hub and cassette.

At a minimum, that movement would create noise from the hub. Meanwhile a cassette that didn't make those marks would remain silent, if you maintained the rest of the hub system. That is why a different cassette would be considered, "Better Designed".

I hope this makes sense and you understand why you are having a conflict here.
