Pain Cave Gear Tracking

How to track your gear usage for indoor cycling trainer setups

Indoor cycling trainer setups are made up of many separate pieces of gear, and it's common for people to use some — but not all of it when they ride outdoors. This makes it a little tricky to properly track how much use this equipment gets, but it's still worth it to do so. Why? Your safety and performance rely on knowing the accurate amount of wear and tear your gear has endured. You don't want to start a race or an intense training ride with a bike part that's ready to be replaced.

Where to start?

The first step is to track the trainer itself, and the cassette (if it has one). If you have a brand new trainer, add it to your gear tracking software right away. If you've already been using a trainer, it's easy to add it to all of your past indoor workouts. SportTracks lets you quickly import your entire history (even if you're just using the 45-day free trial), and then add gear in bulk to specific workouts in just a few simple steps.

Some people have dedicated bikes for their indoor trainer, while others use their bikes both indoors and out. If you have a bike that's used exclusively on a trainer, then it's easy to track the usage. Just be mindful to properly track any gear that may be moved between your indoor and outdoor bikes, such as power meter pedals, like the popular Favero Assiomas.

Bikes with two lives

If you have a bike (or bikes) that you use both indoors and out, tracking requires a little more care. I track every part of my outdoor bike separately, and all of the parts are grouped and assigned to a sport so they automatically get tagged when a cycling workout is auto-synced to SportTracks. It's great because it's all tracked automatically in the background and I don't have to do a thing. For example, I can quickly see that my front Continental Grand Prix 4000 S II has 902 miles on it, and my rear tire has 1490 miles.

I move the same bike indoors during the winter and use it on my direct-drive trainer. So I need to make some quick adjustments to how my bike gear is tracked when I transition to indoor training. I visit the Gear page of SportTracks and remove the following parts from being grouped with my bike:

  • Rear rim
  • Rear tire
  • Rear hub
  • Rear spokes
  • Rear wheel cassette
  • Rear brakes
  • Front brakes
  • Front tire

Note that I remove my front tire from the group, but not my front rim, hub or spokes. My front wheel doesn't spin when I ride the trainer, so I don't want to track miles on the tire itself. I'm still putting my body weight on the front rim, spokes and hub for the duration of my indoor training sessions. Those parts feel that pressure, so I track their use.

HOT TIP: Give your front wheel a little spin after every workout so you don't stress the same spokes on every ride, unless you have the KICKR Climb — in which case I'm jealous.

With those parts removed from my bike group, I then add my trainer and my trainer's cassette as part of my bike. Now my indoor trainer rides will automatically track the usage of my trainer and all of the other parts of my bike, except for the specific parts I excluded.

Considerations for wheel-on trainers

With wheel-on trainers, like the popular Tacx Flow Smart, the rear wheel stays on the bike, but the tire is usually swapped out for a dedicated trainer tire. In this case, you should track the usage of your rims, hubs, and spokes, but you should remove your rear road tire from your bike group and add your dedicated trainer tire. Why track a tire that's only used indoors? So you can celebrate its birthday, of course!

How long will my gear last?

One of the main reasons to track your gear is to avoid overuse to the point where a part fails during a ride. This can be extremely dangerous, so it's best to do everything possible to avoid mechanical breakdowns.

It's critically important to inspect your bike regularly to make sure it's functioning properly. You certainly cannot rely on gear tracking alone to monitor your equipment. Rims, hubs and spokes will show signs of wear, and this should be your impetus to repair or replace them. It's still useful to know how many miles they have served you, though. Brake pads wear out at different rates depending on your riding environment and other factors. This chart only provides general estimates of how long parts last:

Road bike tires 2500 miles (4000 km)
Cassette 5000 miles (8000 km)
Chain 2500 miles (4000 km)
Bottom bracket 4000 miles (6400 km)
Disc brake pads 1500 miles (2400 km)
Rim brake pads 500 miles (800 km)

Now that my indoor training gear is all being properly tracked, I'll know my usage is accurate. I won't be adding unnecessary miles on my brake calipers, front tire, and other essential parts that will go unused for months. The parts of my bike that do get use will be tracked correctly, so I'll be able to service and replace them as needed.

For indoor use, seems like hours is more indicative of use than miles. Why doesn't the gear tracking feature in ST show hours?

That's an interesting idea! Would you mind taking a few minutes and adding it SportTracks User Voice? Here's the link: https://sporttracks.uservoice.com/forums/201951-general

Based on past experience, that seems like the place that ideas go to be ignored.

This shouldn't even need to be a feature request, it was already in the desktop software.
