Buying Guide: 4 Things to consider

Undoubtedly the first and most important factor on your mind will be the amount you are willing to pay. Needless to say, the higher your budget, the most advanced features you will have in your bike computer. When you are preparing for an important event, you will certainly not want to skimp on quality.

So, when looking for a bike computer, you will basically need to consider the four important factors that we have discussed below – navigation and mapping, screen and user interface, data and connectivity, and battery life. Besides these you may want to look for additional perks like compatibility with third-party apps, screen size, and so on.

Navigation And Mapping

So, the most important aspect is navigational functionality and some advanced bike computers just allow you to enter a destination and they will map the route for you. Some devices have software that enables riders to create their routes and upload/ share with fellow cyclists.  

If you like discovering new routes, we highly recommend you to choose a bicycle computer that offers turn-by-turn navigation. Although extra features put a strain on the battery usage, this always keeps you on a safe side on unknown trails.

Data and Connectivity

The basic bike computers will show simple data like speed (average and maximum), time and distance traveled, and so on. Advanced versions sport Bluetooth Smart or Ant+ connectivity (sometimes both) to allow you to pair the computer with numerous third-party devices such as power meters, heart rate monitors, and cadence sensors.

With the Bluetooth Smart feature, you can also tell your bike computer to display incoming calls, text someone, or show email alerts. Some devices come with built-in WiFi to upload ride stats automatically to Strava and similar apps.

Screen and user interface

The appearance of a bike computer matters to some cyclists, but more important is the user interface to help you enjoy a smooth ride. Sometimes, a black-and-white mobile screen may provide improved contrast, but the color displays are capable of giving you more detailed results. However, this will come down to a buyer’s preference and budget.

A bigger screen makes mapping and navigation easier but too big may make the installation troublesome. Coming to the user interface, most of the GPS bike computers will allow you to customize the way data is arranged on the screen so that you can have easy access within reach.

Most of the standard computers have physical operating buttons on the front side, however, the more expensive ones come with a touchscreen. It is a matter of personal preference too as some cyclists prefer buttons over touchscreen for easy control when you are wearing gloves.

Mounting option

The most common mounting system in recent years is the out-front mount that allows you to place the aftermarket mounting system ahead of the stem. These mounts have gained immense popularity because they can be easily adjusted by tilting up or down, based on your viewing preference.

Some products like Wahoo Elemnt Bolt, and Garmin Edge 830 come with the front mount. For other devices, you will need to purchase the mount separately.

Tips To Prepare For Your Triathlon Race

It’s usual to feel butterflies in the stomach before a big event so get enough sleep two nights before to stay mentally alert and physically fit.

Perform a thorough check-up of your racing bike to ensure it is perfectly fine tunes. Consider installing new tire tubes if they are old and make any adjustments in advance.

Check to ensure that your bike computer and other devices like fitness monitor are well charged so that the battery does not run out of juice during the race.

Make sure all your cycling gear is carefully labeled using an indelible marker. Mention your name and phone number inside your biking and running shoes, inside helmet and wetsuit too.

Never use a new cycling gear just before the race and always ensure everything is comfortable and easy to use. From a helmet to bike shoes, give them enough time to break in.

Be aware of the directions before the race starts and study the course to know what you can expect in the next turn – downhill, uphill, or flats. Where are the stations and how many are located?

Do not change your diet before the Triathlon race and follow the same usual diet comprising of rich protein, healthy fats, and a lot of carbohydrates.

If you are participating in a USA Triathlon (USAT), take your number to the officials and get yourself marked. You must ensure that you have photo identification and membership card.

Always make sure that the water bottles are properly filled with a nutrition drink or water. Have your sunglasses, helmet, and hydration belt checked.

Your bike computer is an important part of your game to keep you on the right track so make sure it is well charged and set properly for optimum benefit.
