Chain Slipping on new Ultegra, no idea why...? (Video)

[Pale Rider]

Weirdly I've not used it to cut wood.

As I say, only 3800 miles and I clean and lube the chain pretty regularly as well as clean the cassette, jockey wheels and chainrings.

One thing that changed a few months ago was the LBS taking a few links out of the chain which I thought was odd, as I didn't think Canyon would supply a chain the wrong length? If the chain is too short, could this accelerate wear on the components?

Worth having a word with Canyon?

Your pics are clear and it would be simple enough to email them.

Canyon are supposed to be like Rose, if they are, you might be pleasantly surprised.

Have just done that, will see what they say.

If you get no joy from Canyon, you could try Madison/Shimano via a UK bike shop.

It would be better if it was a UK supplied bike, but there's nothing to stop a UK shop which sells Shimano contacting Madison on your behalf.

They may be reluctant to do it because there will be no money in the transaction for them.

My local bike shop returned the Shimano Alfine hub gear from my Rose bike to Madison, but I do have a good relationship with the shop.

The broken hub was 18 months old, which I told Madison, but to be fair to them they replaced it.

A hub, obviously, is not a chain ring, but my experience may indicate Madison treat Shimano warranty claims reasonably.

Do Madison own Shimano?

Madison is the UK distributor for Shimano, which is Japanese.

Any warranty claims for Shimano bits in the UK are handled by Madison.

A proper bike shop is bound to have returned lots of Shimano bits over the years, so they should be familiar with the process.

Indeed... and Madison are very good when it comes to warranties.

That's kind of how they look when new though isn't it?

apologies I was away all day (hospital0
you are missing scale on that link... that's the problem. on your photo you have scale, the inner chain ring that is visible provides the comparison. they would have been identical when new.

You have been riding with a chain that was well overdue for changing. A worn chain will accelerate wear on the cogs and chainrings. With all-weather commuting, a chain would barely last 1000 miles, so even with a good-weather bike, 3,800 miles is a lot to put on a chain.

Because you put a new chain on - it exaggerates the problem as the old chain would have 'meshed' more with it as the two wore together.

Problem is exactly the same with old chain (3800 miles) and brand new chain & cassette (30 miles).

As above, you need a new chainring.

This is my chain after 3,500 miles since Aug, and chainrings after 2,500 miles on the same chain, the rings were new in Sept, and are Spacycles own Zircal rings I ride 90-95% of the time on the middle 38th ring.

I am replacing the chain this next week along with a new cassette, as the 12-27 just has too many big gaps. Last time I measured the chain there was very little wear, less than 1/16th of an inch, I personal put this down to the fact I have a very straight chain line for most of my riding, as I am usually on the 38x19-15 combinations, something i couldn't do on a compact double, and I wonder if this is why chains are wearing out so quickly.

This is it when it was new.

A chain only lasting 1000 miles, you're kidding me! You must buy chains made of daisys.

Check your rear derailleur is indexing right and its springing back ok. If not its probably cable snag, replace the inners and outer cables. Worst case it could be deraileur failure, clean and lube it first and if its still not right replace.

Have you tried commuting 5 days a week in winter in Scotland? After 8 years I think I know how many chains I went through - and that's with a pretty good cleaning regime.
