Chain length advice - SRAM 1X

Hi,

I have SRAM 1x11 running on my bike.. it originally came with a 42t front ring and a 11-36 rear cassette. I recently changed the rear cassette for a 42t.. so essentially now running 42t - 42t. The current chain is too short.. I want to order a new one but don't know what length.. The bike is a Genesis CDF, so will a normal 114 link chain be long enough and allow me to cut it down? Or do I need to start with a longer 116 - 118 chain? Also I was looking at the PC1130.. is that the correct chain for the 1X setup??

Thanks

Last time I changed chain I think I got 114 links and the chain is barely, just long enough (42/40 drivetrain).
Get longer if available, cutting is easy. PC 1130 is fine, as it's any 11 speed chain.

I run 118 link with a 42/42 drivetrain.

Just get the longest chain and cut it? No one can be sure 100%.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
