Thick thin chainrings
It is weird isn’t it. Basically all it is, is they stop the chain moving around as much, so even though it’s not stopping it moving in the directions that’d cause it to come off, there’s less movement/energy in the system- it doesn’t build up enough bounce to bounce off.
TBH I didn’t really believe in it til I tried one.Posted 4 years agowukfitMember
That’s too thick Neil,Posted 4 years ago
Narrow wide chain rings are built with a fat tooth, thin tooth, fat tooth, thin tooth etc.
The chain will then sit on it only in a certain way, giving less movement and therefore less chance of bouncing off
I’m sure someone can, and will, describe it betterdannyhMember
The teeth are also a bit taller than a regulation chainring (they can afford to be if the chain doesn’t need to come off of the ring to shift).
Anyhow, these things WORK! Pair it with a clutch mech and you will enter drivetrain heaven. Almost noiseless descending no matter how rough, and the chain will still be there to pedal away afterwards.Posted 4 years agowobbliscottMember
Go on, i’ll have a stab at it….I think the clutch mech maintains chain tension which us a significant help. However in a slow mo video I saw the way a chain is dropped is as it waggles up and down there is also a sideways waggle so when you put in a pedal rev the sideways waggle causes the chain to derail. With a thick thin ring the better lateral engagement due to half of the link now filling the gaps in the wider links the sideways waggle is also reduced. Anyway i’m guessing, but as said before, they work!Posted 4 years ago
Joining the 1×10 revolution Neil? Did the impossible hill three times today on my single ring set up before my legs stopped working. Turns out it should be renamed
I think you did the hill of death in Ballure . the Impossible hill goes from Glen Auldyn to the top of Brookdale .Posted 4 years ago
If you can clean the impossible hill 3 times with a 1×10 set up in a single morning I will eat all of my bikes .robarnoldMember
