Wahoo Speed and Cadence Sensors

What do you think of the Wahoo speed and cadence sensors? How about the two individual versus the combined unit with the spoke magnet? Thanks

I don't have the magnetless sensors yet, but I have several Blue SC (both the BLE only and the Dual BLE/ANT+ versions) and they work great.

I don't have one, but I'm intrigued by the possibility of mounting the cadence sensor on my shoe, as I have multiple bikes.

A few of the Amazon reviews mention erratic connections under some circumstances though, so I'm still on the fence. Ideally I'd like something that can connect simultaneously to the Garmin (ANT+) on the handlebars, and my phone (BLE) which usually stays in my backpack recording the ride in RideWithGPS.

I have the Blue SC and it works great. No problems with it other than a few speed spikes that's easily corrected with a reset. If you go with any of the Wahoo sensors, be certain to install the Wahoo Utility on your smartphone so you can update the firmware when a new version is released.

Does your Garmin not have GPS or do you just like the redundancy of having two devices track the same ride?

Mostly the Garmin Oregon 600 works fine by itself and I've been using it for a few years now. I mainly use it for the map display (with GPX track overlay) and recording. It's just that lately I've been experimenting with the RideWithGPS app on my iPhone, and finding that I like it for a variety of reasons as it addresses some of the shortcomings of the Garmin. Unfortunately, I also have some reservations about going phone-only. So, since I already have the Garmin, I've been kind of mashing up the two -- phone for tracking, uploading, and turn-by-turn voice prompts, but safe and dry in my backpack, and GPS for live maps and withstanding the elements. Ideally I'd want ANT+ so I can see cadence on the handlebars, but BLE would also be cool so cadence would record to the phone and I could upload directly to RideWithGPS. It's not a big deal to lose cadence on the upload, it just would be nice to have if I can get it "for free".

Since I do a lot of exploring in unfamiliar areas, the redundancy certainly doesn't suck though, both as navigational aids and recording devices.

Well, that makes more sense now.

I have the Blue SC which is both Ant+ and BTLE and two RFLKT+ devices. Just to see if the Blue SC really did transmit both signals simultaneously, I connected via BT to my iPhone using Cyclemeter and the second RFLKT+ to my wife's iPhone, also using Cyclemeter, via Ant+ and did a ride. It definitely transmits simultaneously but I did notice a few more cadence spikes with the Ant+ connection.

I found them to be erratic and requiring too much time fiddling around. I went to a Garmin 810 and everything just works with no fuss, no muss.

I have the opposite experience. Got them on three bikes and they work fine every time. As with all magnet based sensors, you have to make sure they are aligned OK, but that's true of any brand.

I am glad you have had success. The whole alignment thing is the issue I found frustrating, first to get it to align so it worked and then frequent readjustment from use or the occasional bump. With the Garmin it was so easy and quick to set-up, no alignment required and the computer quickly connects to the cadence, speed and HR sensors.

The only way my sensors get out of alignment is if I kick them by accident. I'm using the rubber band to keep them on the bike as well.

I assume the Garmin sensors you got were magnetless ones?

Yes that is correct. The speed sensor attaches via an industrial strength band around the rear hub and the cadence sensor attaches with a band on the crank.

Yep, those are easier for sure. Wahoo makes them too, but if you don't care about BLE support the Garmin ones are cheaper.

I just picked up a Giant, Bluetooth and Ant+
https://www.amazon.co.uk/Giant-Bluet.../dp/B019H5G0JI

I've never used a wireless unit before but it seems great. It works with any app I've tried. The range seems great, and the magnets to me seem really strong. You can hear the switch in the pickup (in a quiet room) and they work from maybe 2 cm. So far I've only ridden with the phone in the seatbag, but I don't anticipate any problem with it farther away. It doesn't attach with a loop. You must use cable ties. Oh, I have no idea about battery life.

One issue I've had with Garmin magnetic sensors is that if you happen to store the bike with a wheel or cadence magnet too close to the sensor, it can prevent the device from going to sleep and will drain the battery in a matter of hours. I'm not sure if all of them do this or just the old Garmin GSC10, but in my case, inevitably once every few months or so I'd forget to check the position of the pedals or wheel and end up with a dead battery. That's one reason these magnetless sensors are interesting to me, though I'm sure they must have drawbacks as well.
