no idea about the warranty of mine. I bought it with the thinking that because it was cheap, if i broke it i could just get another one.

idiots setting up gears and worn chain rings cause chainsuck !

frames dont cause chainsuck rappers do 😉

Warranties cover manufacturing defects, not user error.

My 456 chain sucked from the word go with brand new drive chain all set up perfectly.

More recent versions that I've seen have a big dink in the stay to minimse the problem. IIRC Brant used to tell people to hit the stay with a big hammer to enlarge the clearance – but that could be urban myth.

While it's worn drive chains and dry/muddy chains that cause the problem, the closeness of the stay to the chainrings mean that it's much more likely to happen (or less forgiving of less than perfect rings, chain etc if you want to look at it that way…)

Warranties may not cover user error but should cover shonky design.

the sanctimonious set need to calm down a bit I think

any drivetrain that uses a sprung rear derailleur chainsucks if

a) you've used it for more than about 100 miles offroad
b) you ride more than about 10 miles between cleanings (ed – if it's muddy)

sure, the extent is variable & depends on things like how bad your chainline is (crossing the whole block etc), soemtimes badly timed chainring shifting as well as how kacky your chain is, what sort of kack it actually is, & other stuff but to deny it happens on properly set up bikes is stupid

what matters (until you get ludicrously bad chainsuck) is how close your chainrings are to the stays. Bikes trying for big tyre clearance are always at greater risk of chainsuck damage

and please explain how badly adjusted gears contribute ?

I lurve this diagram me 🙂

Am I talking to you ?

no geoff, you're the pedantic set 😉

Never heard a bad thing about On-0nes warrenty, christ I got my inbred at warrenty replacemnet price because my carrera had developed a crack (brant felt sorry for me and was half leathered).

No chainsuck either with HT1 (XTbb/lx crank) and I'm the laziest bastard in the world when it comes to cleaning, so much so I've alfined my 456 (tyres are all 2.35's).

Hard to see how you can go wrong, cheap frames with proven geometry.

No he really did, though the evidence was probably lost with the old forum. I did this to my 853 Inbred about 2 years ago, much better.

The best option is to limit chainsuck happening. I've got an 853 Inbred and found that good old Deore steel inner and middle rings help, lube can also make a difference and keeping things nice and clean helps also. To be honest I think that even the most well cared for drivechain can suck so it's also good to have some damage limitation methods for when it does. I've found that the chainring clearance is so tight the the chain just cuts through zipties. I'm currently trying out a chainsuck plate, but these seem hard to get hold of and are fiddly to fit with On-One's wide stays.

I've noticed chainsuck seems to increase with a new drivetrain or chain for a while (wearing in?).
