chain length calculator.pngCycling app of the week: Chain Length Calculator
What is it?
Chain length calculator does nothing more and nothing less than working out what the length of your chain should be, expressed in number of links. You can use cm or inches to input your chainstay length (you should always be able to find this out on your bike manufacturer's website inventory or in the manual it came with), and then add your outer chainring size and number of teeth on your biggest cassette ring and hey presto, it's done.
What makes it unique?
The simplicity more than anything - although there are plenty of similar calculators you can find on websites with a quick Google, but this saves you a bit of typing once you've got the app and it doesn't really take up any space on your phone.
How can it help me?
It works out how long your chain needs to be of course! While you can just go by the "big big and add two links" method, this takes out any estimations whatsoever and makes life that little bit easier if you're not confident of getting it spot on.
Where can I get it?
Unfortunately for iPhone owners this app, which can be downloaded here, is Android-only... but we've found one very similar on the iOS store here.
Jack has been writing about cycling and multisport for over a decade, arriving at road.cc via 220 Triathlon Magazine in 2017. He worked across all areas of the website including tech, news and video, and also contributed to eBikeTips before being named Editor of road.cc in 2021 (much to his surprise). Jack has been hooked on cycling since his student days, and currently has a Trek 1.2 for winter riding, a beloved Bickerton folding bike for getting around town and an extra beloved custom Ridley Helium SLX for fantasising about going fast in his stable. Jack has never won a bike race, but does have a master's degree in print journalism and two Guinness World Records for pogo sticking (it's a long story).

How often are people changing chains that they'd need an App on your phones? If you're using this App more than Strava (or any other App) you're either not riding enough or you have a serious problem!
needs access to wifi information....why?
Because if you're stupid enough to need an app to fit a chain then you're sure as shit stupid enough to be suckered in by the advertisers the App will surely drive to your phone
well quite. it is a calculator. it doesn't need to do anything more than calculate. why is everyone trying to coin it in on your data? just no.
