I have had a cadence-counting computer forever. I have an old Cateye Astrale on the bike right now, but it has become intermittent; I suspect the contacts between the mount and the head unit. I am not interested in using an iPhone for this task; most of my rides are the same routes over and over, and a simple dedicated unit will suffice.

The (discontinued) Astrale is wired, and the sensor wire runs up the underside of the downtube. It catches an awful lot of crap, and I would consider a wireless unit, just to make it easier to clean the downtube. While I'd rather just keep the Astrale running, I have to look ahead. Can you recommend/disqualify a wireless cadence computer? Thanks.

While I have really liked the two button Cat Eyes of the 1990s and 2000s their current crop doesn't do it for me. I also ran cadence for decades (starting with a Push then Avocet for a long time) but I'll say that like heart rate cadence for me these days is a non issue. I know I spin well and feel wrong when I push squares. (Just like I can feel my heart really beating fast...) So I've retired my need for cadence and now use the past generation of wireless Cat Eye two button computers.

I'm afraid that the industry is leaving people like me and the OP behind, those who want no power or heart rate and never on a smart phone. My routing functions are carried my a Velcro map clip and a bell with a compass. So I guess that this post has no help but some empathy. Andy

as much as I'd like to use the smart device for all my bicycle's electronic duties, it just is not practical for me. I went with a cheap wireless unit off amazon that displays rpm, mph, time, distance, & temp (F). As a bonus, it is capable of being backlit with a pres of a button. I do not recall the price I paid & I'm unable to recollect the brand of it, but honestly, the risk of it working out of the box was iffy based on the reviews. You might consider the route I went should you not worry about brand name & are willing to gamble.

Cat Eye still shows the "Strada" as a current product offering cadence. It is wired however. Here is Cat-Eye's web page: https://www.cateye.com/intl/products...ters/CC-RD200/

I have an older Astral on the bike I use on my indoor winter trainer, mostly because it picks up it's speed, distance, etc. from the rear wheel. I has a cadence function but i find i almost never use it.

If you want wireless buy a GPS/ANT+ computer, anything else is either junk or almost the same price as a GPS. The cheaper wireless units are too prone to interference.

Basically, if you want cheap, get a wired computer. If you want wireless, get a proper GPS headunit.

As HillRider noted, the Cateye with cadence is now the Strada: https://www.rei.com/product/751831/cateye-strada-cadence-bike-computer

I find the single button rather fiddly; it operates when it feels like it, not when I push it. But my 13-14 year old Cateye was getting to flaky to keep using it. (I'm babying the 12-year old Cateye on the other bike with semi-annual dielectric grease and crossed fingers.)

I picked it based on intensive research and reading reviews -- er, no, I went to the auto parts store and asked for some dielectric grease. When they brought out a $20 tub I asked if they had anything smaller, and left with a $3 packet.

I find that keeping the shoe/computer underside contacts clean is important. I use a pencil eraser. I also find that battery condition comes into play WRT the contacts' condition. The older the battery the more the poor contact's effect things. Andy

I like Sigma BC 23.16, it has wireless (not ANT or Bluetooth though) speed, cadence and HR, altitude, no GPS. I picked it for $80 on sale, may not be worth it at full MSRP given that some GPS computers are getting cheaper. On the other hand, you can take it on a tour without the need to recharge it like a GPS one.
Their BC 14.16 STS has optional cadence, altitude and temperature, but no HR. Wired version of 14.16 has no cadence.

I second the pencil eraser and new battery suggestions.
I also have CatEye Astrale's on my bikes. When I saw they had been discontinued, I bought a couple from EBay, as they don't last forever.
If you don't care about the rear wheel sensor, Nashbar has a wired computer with cadence that I put on my daughter's bike. It works OK, don't know about durability because she decided she didn;t care and doesn't use it!

I have a couple of CatEye Wireless II's. They work find for awhile but now are intermittent even with new batteries and clean contacts.. Converted to using Wahoo sensors and an Android phone. Don't need to watch anything, just review at the end of the ride. Since I carry the phone anyway, why not use it. The app I use is Ride with GPS.

Oxguard is a conductive paste I use on my Jeep contacts. It performs the same function of a dielectric but improves conductivity. Just have to be careful not to allow the paste to bridge between the contacts. Dielectric grease is good for sealing out moisture but is a non-conductor.

Dielectric grease does not conduct electricity.
There is such a thing as "conductive grease". I have no experience with it, so I can't comment... but it might be worth a look.

I have a decades old ciclomaster,(German) I could add a cadence sensor, wired , but I dont.
