Crank Keeper

Crank Keeper gives you a place to keep track of all your bike's components and maintenance records.

If you are new to Mountain Biking, here are some things you need to know:

1. You are going to have to change those brake pads before they get to bare metal.

2. Your chain is stretching and will eventually break if you don't replace it.

3. Your tire sealant is going to dry up and you will be stuck on the trail installing a tube.

4. You are going to upgrade parts or your entire bike someday.

Crank Keeper gives you an estimate of age and miles for each part of the bike so you can quickly discern when to take action. It's also a great place to describe your bike parts in detail so at upgrade time you have the information you need.

FAQ

Why did you create this?

1. My tire went flat because I failed to add sealant. Yeah I thought it had only been a couple months, turned out it had been much longer.

2. I was trying to get a quote on a new fork and I didn't have the details on my current fork.

3. I'm a software developer and I enjoy writing software for me instead of for the man.

How am I making money off of this?

There are no ads and this app is free. Within the app if you hit the shopping link for one of your bike components, I may get some kick back from amazon when you shop there.
