How many extra chain links

richard_farrant

Hi

Got a new cassette and chain to fit today, had a 12-25 before and going to a 12-28. When I have changed chains before I have just lined the old and new against each other but I don't know how many additional links would be needed to allow for the 28t cog?

Any thoughts?

Cheers

Rich

1. Put casette on wheel on bike
2. Wrap chain around big ring and the 28 cog and see where chain touches
3. Add 2 links

That's what I've done in the past

Works every time for me. Just need to measure the chainstay length on your bike and input this along with the largest front and rear cog sizes
