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.

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...

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

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.
