Gone 1×10 – Skipping chain; 2nd opinion please…
Okay so this could be a simple fix or could be more tinkering required.
I swapped over to 1×10 today, Hope IBR & guide, plus new KMC chain with magic link( i think thats what its called)
The chain is skipping under pressure in the 11 & 13 gears.
The bike is just under 6 months old and was only at .75 on the chain checker tool.
Is a worn cassette causing this skipping/slipping or possibly something else?
I’m guessing that I’ll need a new cassette, just wanted a 2nd opinion as to what might be causing it.
If so can somebody recommend me a 10 speed Shimano one please
Thanks!!!Posted 5 years ago
I didn’t get a chance last night but will try to fix it today. I don’t think it’s the indexing because it was shifting really well yesterday but I’ll have another look.
Chainline is a possibility, the chainring is mounted on the inside of the spider & I’ve not used any shims because this would have pushed it in closer to the seat tube. The other option would be to mount it on the outside of the spider but I’m not sure that would work? I just assumed that it was supposed to be mounted on the inside?Posted 5 years agosinglecrackMember
I had this when I first went 10 speed …..the chain I used (can’t remember which ) the links are to wide in depth …so when it rolled over the 11 sprocket the chain would not lay in the teeth properly because of the small radius of the sprocket and so would rise up on the teeth allowing it to skip …changed to shimano chain …problem solved …….
But it woul work ok on 13t sprocket ..so may not be this problemPosted 5 years ago
Thanks for that singlecrack, the chain I fitted is a KMC X10 93.
Was the problem you experienced obvious when you were off the bike and just peddling the chain round with your hand?
When I peddle the chain round using my hand and the bike in the stand it works fine and I don’t notice any problems, it backpedals too without dropping. As I mentioned above it happens about every 2/3 pedal stroke when it’s under load.Posted 5 years agosinglecrackMember
I only noticed when under load …..I managed to put it on a stand and pedal it with my hand and held the back brake gently applying more pressure
My set up was all brand new cassette / front / ring / chain ….so that ruled out wear on my part
Like I said it may not be the same problem
Just checked as I still have the old chain ( it was only used for one ride) Its a connex wippermanPosted 5 years agoallmountainventureMember
Cassette wear, seems a bit fast in 6 months? And also the 11T is usually one of the least worn, the climbing sprockets tend the get the most wear (not always mind). How does it look, are the teeth hooked/shark finned?
Maybe you could upload a close up photo of the block?
If the old chain works fine you can pretty much rule out indexing, limit screws, bent hangers and etc.
What sort of magic link are you using? If its a 9spd (gold) link that could do it.
Possibly its just a new chain that needs to settle in a bit.Posted 5 years ago
Okay so i put the old chain on and I wasn’t having the problem, it was working fine standing up under load, something that I wasn’t confident enough to do using the new chain because it was slipping while sat down and peddling.
The old chain is the one that came with the bike originally, a Shimano one that is now stretched to .75 on the chain tool, the 1. end still doesn’t fit in.
What is it best to do here? I’d rather buy a new cassette rather than continue to use the old chain because presumably it will wear the chainring out much quicker?
As I say I don’t know what to look for to know if the cassette is worn? Does that look like it needs replacing?
Sorry for all the novice questions, I’m really grateful for the help and advice you have all offered, thank you all very much.Posted 5 years agoallmountainventureMember
Cassette doesn’t look too bad really… In the first picture there looks to be a bit of wear but not much (it could be dirt build up tho), the second picture it looks pretty good. By comparison my block is shagged but it still takes a new chain ok.
Before spending on a new block its worth seeing if the chain settles down after a few km gentle riding. Some times that happens.
I’m assuming you are using a 10spd power link? A 9spd one may catch every few stokes as you describe.Posted 5 years ago
I brought a new XT Cassette and changed the gear cable and housing and it’s shifting like a dream!
It’s amazing how much difference it has made, it feels better than when I brought the bike new.
Toying with the idea of a Zee rear mech now as my jockey wheels are quite worn on my XT mech and they cost almost a third of the price of the Zee unit.
Just a big thank you to everybody that gave me advice!!Posted 5 years ago
