What's the Chances?

[HLaB]

I've finally got round to ordering a new chain but after 3932 miles what's the chances of it not slipping ? Personally, I think no chance and a new cassette will have to follow

 

[tyred]

It depends on how badly worn the old one. On the old style 5 and 6 speed systems on my bikes, that is only running in mileage.

It did slip about 5 or 6 times in 16 miles tonight but I cant rule out sticky cables (the bike really does need new outers) in all cases and never when the chain was under real pressure (climbing hills). I think I can live with that but is that a wise thing to do or should I replace the cassette immediately ?

You'll force the new chain to fit the old cassette, so in a matter of a couple of weeks your new chain will be as long as your old one. Change the cassette asap

Cheers, I've lubed up the rear mech and cable to see if it was sticky cables causing the occasional jump but I doubt it, and I think a new cassette will be in order, I've managed to find a tiagra 10sp for a bit cheaper than my old 105 10sp. Merlin and Shinybikes are selling the 105 for circa £34 but I've never used them before so I don't know if they are any good?

I've used Merlin a few times, enough to confirm they exist.

Not had a problem, but that could just be chance of course.

I took it back out for a ride tonight with clean and lubed cables/mech on the same 16mile loop and it only slipped twice but I think a new cassette will be in order.

 

[HLaB]

It maybe was sticky cable, the chain never jumped at all during the 38 mile club run or the short 2 miles uphill to the start, perhaps I'll get away with keeping the old cassette after all

 

[cyclingsheep]

one other option may be to see if it is a stiff link? If when joining the chain you haven't made sure the link is suitably free moving as it comes through the jockey wheels and onto the cassette it can cause slipping under load. Just a thought to make sure before shelling out for a new cassette

Or your nice new chain has already started to bed in to the worn cassette and will give you trouble when your new cassette arrives

I'd be tempted to put the old chain back on and run the chain/cassette to destruction then replace both.

I ordered from Ribble in the end as they had a sram 11-26 cassette for the same price and merlin were out of stock of the 11-25 105 (only had 12-25) and a fair bit more expensive for the Sram. I fancy minutely lower gear without losing my top gear. I'm impressed with Ribble, ordered Wed (around 16:30), processed and dispatched yesterday and delivered today. I also got my self some new bar tape and cables. I'm still undecided as to whether to fit it or not, I've had a few rides where there has been chain slip and a few where there wasn't I'm suspecting sticky cables and its not completely worn out. My instinct say to swap it but keep it as a spare.

Fit it!

You might gain a few extra km using the old one but is that really worth it? What are you saving? And you'll always be unsure of the old items.

Besides, chains & cassettes are consumable items and need changing. Bite the bullet and get into the habit of doing it regularly. There's nothing like a new, clean shifting drive chain! Transforms the bike.

Do it, you know it makes sense
