John Radmore from Canada has broken his chain and wants to know how to work out the correct chain length. We give him the two most useful methods of knowing the correct length. A handy thing to know!
Question:
I have a pro tour and my chain broke. I would like to know how long the chain should be. Hope to hear from you soon thank you.
Hi John,
If your chain has broken then it may be time to buy a new one as it is either worn or damaged. Now there are two different ways to get the length of your chain correct, here they are:
The Shimano Method.
The preferred method of fitting a chain by Shimano is that you put the chain around the large chain ring and the large sprocket, with out threading the chain through the rear derailleur, where the chain meets and then add two links and cut the chain at that point.
The Other Method.
Put the chain round the small chain ring and the small sprocket and through the rear derailleur, then the spring in the rear derailleur should take any slack from the chain. Buy holding one end pull the chain together until the spring of the rear derailleur takes the strain and that's where you need to cut the chain.
When your chain broke I hope you were not climbing off the saddle at the time? That can hurt!
