I'm looking to replace the chain on my Trek FX 7.1 w/ an SRAM 850 because I have been neglecting maintenance and it is way overdue.

Is there any reason why this Topeak 2011 Chain Tool won't work?

Am I better off getting the Park Tool Mini Chain Brute?

Any other tools I will need to replace my chain?
