April 24, 20179 yr I'm always pointing out that chain-wear is not a serious problem and my chain is working fine after 4000 miles; however, recently my gears started slipping, so, rather than mess about, I decided to eat a bit of humble pie and replace the chain and the cassette (free-wheel gears). Here's the cassette: Some will notice that some of the teeth look like shark's teeth instead of sprocket teeth, but when I show you a new one, you'll see that they're the same. So, I put a new chain on along with the new cassette, but the slipping was worse. I couldn't figure out why. The gears worked perfectly on the stand, but as soon as I put pressure on the pedals, the chain slipped. Then, ding ding ding, the penny dropped. I was looking at the wrong thing: I bought the crank-set as a used one from Ebay when I built the bike three years ago. The chain-wheel is only aluminium, and I've no idea how many miles it had done before I bought it. Anyway, I got a new one from Ebay for £8. It's a Chinese replica of the original Shimano one. It would have saved me a lot of work if my guilt from boasting about chain and cassette wear hadn't got the better of me. At least I know that I can look forward to another 4000 miles without any problems:
April 24, 20179 yr Funnily enough the guy I commute with went through exactly the same discovery today.... totally forgot about the chainring. Finally forced into action after a few heart stopping moments trying to navigate rush hour traffic, slipping everytime he put the power down. John
April 24, 20179 yr I've done the same, changed the chain and then drove 50 miles to go mountain biking, only to find the bike unrideable when I got there. I knew better than go out without testing the bike before, a moments laziness cost me a couple of hours wasted time, 3 gallons of petrol and an afternoon of riding new trails. What a pillock!
April 24, 20179 yr Always worth changing front and rear as well as chain at the same time or the worn sprocket will wear the chain much faster than a new one.

April 24, 20179 yr How much longer was the old chain than the new one? That's a bit of a sore point. I counted the links and found that they both had the same number, but actually, the new chain was quite a bit longer, as I found out the first time I switched to the middle chain-ring, so I took two complete links out (4 links if you know what I mean), and I still can't use the small chain-ring. Either it's stretching at an extraordinary rate, or somebody needs to go back to school. I should have laid the chains together side by side, but to save getting my hands dirty, I always use the old chain to pull the new one through.

To clean my hands a use veggy oil, sugar or salt ,then ordainary bar of soap, works for me!
