Cateye Strada Digital Wireless - With Heart Rate and Cadence Sensors

One of my main reasons for getting a road bike is to try and see how different it is compared to my road-bike-like folding bike, the Dahon Boardwalk. Besides the general feel when riding the bike, it will be useful to have some form of measurement, such as the cruising speed or max speed on these two different bikes.

Therefore I needed to get a new speedometer for my Merida Scultura 5000. With the wide variety of options available in the market, there is no shortage of good speedometers or cycle computers. The difficult part is choosing which is suitable for you, and what features you are looking for in the cycle computer.

In my opinion, Cateye is the current market leader for cycle computers. They have many different models of cycle computers to suit different riders and price points, and they are always reliable.

Garmin is another brand that is rapidly gaining market share in the cycle computer market. The main draw of Garmin computers is the ability to link up to the phone or internet, and to locate or navigate using the in-built GPS. The large amount of data available makes it super useful for training, where numbers and statistics are important. The downside is the high cost of owning a good Garmin computer. At the entry level there is the Garmin Edge 200, with very basic functions, which is available for about $150. Those who want good connectivity and additional sensors can look at the Garmin Edge 510, which costs $450 locally inclusive of the cadence, speed and heart rate sensors.

Due to the high cost of the Garmin cycle computers, I decided to get a cheaper Cateye cycle computer instead. This model does not have GPS, which I don't need anyway.

Cateye Strada Digital Wireless CC-RD430DW. This model includes the cadence/speed sensor and a heart rate monitor chest strap.

The standard functions of a Cateye cycle computer are all there. Additional features include a 2.4Ghz wireless frequency for lesser interference.

Using 2.4 Ghz will avoid interference from other cycle computers and bicycle lights, but may be prone to other sources of interference such as Wi-Fi or microwave ovens that operate near this frequency range.

It is possible to use the cycle computer on two separate bikes, each with its own sensors.

The large sheet of instructions that are typical of Cateye cycle computers. Mostly confusing and difficult to interpret.

Installation of the sensors and cycle computers are easy, if you have set up Cateye computers before. If not, you will need to take some time to read the instructions carefully and figure out how to mount each part properly. I have installed Cateye cycle computers on 3 other of my bikes, so this is no problem for me.

The cadence/speed sensor is mounted on the left chainstay of the Merida road bike. The position is mostly determined by where you place the magnet on the left crankarm.

Use the rubber mount and the cable ties to fix the sensor securely to the left chainstay.

The long arm of the sensor detects the speed by reaching towards the spokes of the rear wheel.

Install the magnet on the spoke, at a position where it will move past the sensor. The sensor arm can also be adjusted if it is too far from the magnet.

For the magnet on the left crankarm, you can install it this way without using cable ties. Just stick the magnet directly to the spindle of the left pedal. 

I did not use the crankarm magnet that is provided with the package. In order to ensure that the magnet will stick securely to the pedal spindle, I bought some powerful neodymium round magnets (12mm) and stuck it to the pedal spindle. Since your spindle is made of steel (unless you use expensive pedals with titanium axles), the magnet will stick securely to your pedal spindle. It is very secure and will not drop off even when cycling over bumpy roads. This method eliminates the unsightly cable ties on the left crankarm.

With the powerful neodymium magnets, the cadence sensor can be located slightly further away and it will still work properly.

Cycle computer mounted on the handlebar

In order to make some space for the front light and my Topeak phone pouch, I actually went to get another Bar Fly Bracket for this new Cateye cycle computer.

Just sufficient space for the Cateye cycle computer, the Moon Comet Front Light and the Topeak Smartphone Drybag 5".

After testing it for a couple of weeks, here are some of my findings for the Cateye Strada Digital Wireless cycle computer.

Pros:
1) Small and lightweight.
2) One battery will be able to last 1 year, and does not need to be recharged frequently unlike Garmin units.
3) No interference by the Moon Comet front light, which will cause interference to the older Cateye Strada wireless cycle computer if placed too close to the computer unit.
4) Automatic linking of the cadence/speed sensors and HR monitor once the computer is activated by pressing the screen on the cycle computer.
5) One of the more affordable and reliable cycle computers that includes cadence, heart rate and speed sensors.
6) Simple one button operation

Cons:
1) No data logging by the computer. The cadence and HR that you see on the screen is the current reading, there is no way to record it against time or distance.
2) No backlight, which makes it difficult to read at night if the street lighting is dim.
3) No GPS for route logging or navigation.
4) No way to link or upload data to the computer.

In summary, this is a good cycle computer for those who just want to see data in real time, and don't need any post-ride data. The display shows the current cadence and heart rate which I find useful in helping me to control my efforts and achieve the target heart rate and cadence. As for those who want to record their cycling route or study the ride data after the ride, you will need to look at higher end cycle computers from Garmin, which will log down all the ride data for post ride study. Ultimately there are different cycle computers to suit different users and purposes.

Bar Fly Bracket for Cateye

The handlebar space on my Dahon Boardwalk is always very limited. Due to the number of gadgets that I like to install on my bikes, there is always insufficient space to put everything. This problem is even more obvious on the drop bar, as it has even lesser space than a flat handlebar.

Previously I had installed the handlebar extension mount, which creates more space for handlebar accessories. After changing to a new dropbar and stem, I have rearranged the accessories as shown below.

Handlebar Extension Mount with the speedometer and gear display mounted on it

Both the Cateye Strada Wireless speedometer and the Alfine Di2 Gear Display goes onto the handlebar extension mount. This puts the displays further ahead of the handlebar which makes it a bit easier to read.

This set up has actually worked very well for me, giving me the space I need to put the accessories on the handlebar. However, recently I had the idea to remove the Fork Accessory Bracket that is on the Dahon Boardwalk. Although the Lezyne Super Drive XL front light is currently mounted on it, I want to remove it from the front of the bike to make the bike look less cluttered.

My idea is to remove the Fork Accessory Bracket to free up the front of the bike

So how is all of these related to the new item which I want to review below? The overall idea is that after removing the fork accessory bracket, I will still need a place to mount the Lezyne Super Drive XL front light. The only place that is possible would be on the drop bar itself. However, the space there is very limited.

Therefore, I decided to get the Bar Fly bracket for Cateye speedometers. It will free up some space on the drop bar / extension mount, and hopefully making enough space for the Lezyne front light to be mounted on the handlebar.

Introducing the Bar Fly for Cateye!

Bar Fly for Cateye speedometers. They are also available for Garmin computers.

Compatible with most Cateye wireless speedometers. Designed for oversized 31.8mm diameter handlebars, but can also be used on narrower handlebars with the appropriate shim.

The bracket extends just beyond the stem and puts the Cateye display in front of the handlebar

The final arrangement of the accessories on the handlebar. I moved the extension mount further to the right to make space for the Cateye mount. This creates sufficient space in the middle to mount the bracket for the Lezyne front light.

Lezyne front light has not been fixed on yet.

I feel that the Bar Fly bracket is rather useful if you want to make space on the handlebar for other accessories. Otherwise, it is easier to just mount the speedometer directly on the handlebar itself. The Cateye speedometer also fits much more tightly on the Bar Fly bracket than the original Cateye bracket. This makes it harder to remove the speedometer, which is thankfully not a big issue as I only need to remove it once a year to change batteries. However, if you have a Cateye speedometer that requires regular charging (such as the Cateye Stealth 50), this will make it difficult to remove the speedometer for charging.

In the next blog post, I will write about the things that I removed from the Dahon Boardwalk to cut some weight, and also show the new mounting position of the Lezyne front light.
