5 Stars Great bike computer with cadence
It took a good amount of searching before I was able to find the Vetta RT277, which also has cadence and under $30. I didn’t want a wireless bike computer because many have reported the transmission isn’t that good and for me, more batteries to replace. I also like the wired RT2xx series computers because of the thicker, steel braided wiring. The wiring should hold up better against damage if it’s snagged.

The installation on the RT277 is very straight forward and it comes with a spacer to properly align the sensor and magnets. Also included are rubber mounts that are flat and offset depending on where the computer will be attached on the handle bars, along with zip ties and tape for the wiring (they don’t recommend using zip ties on the wires), plus a clear (spare) cover for the computer.

I’m using it on a ‘08 Specialized Stumpjumper FSR. The speed sensor for the wheel spoke magnet is too far spaced from the chainstay on the SJ FSR. I used a sticky rubber feet (similar to the sticky felt circles, normally used items to prevent surface marring) on the chainstay to get the speed sensor closer to the wheel spoke magnet. One thing to check for before zip tieing the cadence and speed sensor is identifying which one is which. The sensors are not labeled. Take one of the magnets and make a few passes over the sensor to identify it. Aside from the manual neglecting to mention which sensor is cadence and speed, this is an excellent computer with the cadence feature.

Feature wise, the computer has the usual: current speed, average and max speed, indicators if you’re above or below your average speed, tripometer, odometer and ride timer. Being a cadence computer, it also has current, average and max cadence. It has service or maintenance reminders either based on ride time or distance (handy for maintaining suspension components). It also has lap functions to track time or training purposes–I haven’t used this feature though, mainly bought it for speed, distance and candence functionality.

1 Star POS
I have had this for several months and still can not get the cadence to work. Don’t waste your money on this POS.

Update – After numerous emails with the mfg’r and the total lack of function of the unit, they finally agreed to replace the unit. Waiting for their response with a non functional unit and about to go on a trip, I bought a Cateye with cadence and it works fine. So much for Vetta. Now let’s see if I can get my money back.

1 Star Someone tell us how to buy a good bike computer please.
The Vetta RT277 is a bike computer that provides cadence, still can’t get it to work right, and distance and speed (all ok here). I use this on a trainer in my basement…that is proabably all I would recommend it for. IF you plant to use it on the road, buy your own plastic zip ties. The ones that come with the computer are about as cheap and poorly put together as the instructions and the device itself. Altogether, it works but I’m relatively disappointed with the quality of engineering and thought into actual installation and use that went into this device.

5 Stars Great cyclecomputer
This computer works great. The wiring for the pickup is even long enough to mount the wheel speed on the rear wheel. I was using a wireless computer and having trouble with interference and false readings…this is leaps and bounds better!

4 Stars Vetta RT277
The installation was more complicated than any other cadence computer I have ever installed. The heavy duty cables are unwieldy, and the separate runs to the chainstay and seatstay add effort. Even the positioning of the magnets seemed finicky. I was doing two bikes, and it took hours before I was satisfied.

BUT, once everything is in place, the operation of the computer is great. Because the top and bottom rows can show any of the data, there’s lots of choice as to what is shown.

The ability to get different colored cases from Vetta is a nice feature.

3 Stars Problems getting started! Save $ and aggro and go with a Cat Eye
I purchased this computer despite the negative reviews and got bit. Installation is relatively simple for anyone who can change a battery, but the instructions are horrific, diagrams only and very unorganized. Installed the cadence transmitter, speed / spoke magnet and computer in a few minutes, but I had difficulty getting the speed sensor to align on my Cinelli’s ovalized fork and the magnet to stay secure on my bladed spokes. It just never appeared to sit well on the fork, so I used double sided foam tape and heavier zip ties than those provided and epoxyed the magnet to the spoke.

I experienced the same “battery” issues (2 DOA) and installed 4 fresh batteries so I wouldn’t have to mess with it later. I also had a real problem with a defective speed sensor, which necessitated a return. The customer service rep was friendly, helpful, recognized that the manual s&%$ed and sent anew sensor and revised(?) manual diagram for the speed sensor install within 2 days. I guess you get what you pay for! Thoma59

1 Star Great Design, But Performance is Challenging
I bought this based upon bike store recommendation after having 3 Cateye’s fail in the past 3 years. Installation was very easy once I figured it out (the manual is only marginally helpful). I really like the display – very easy to read for those of us over 40. The O’rings do not hold the speed and cadence sensors very secure – they tend to move out of alignment while going over bumps. I trashed the cadence sensor when it slipped into the spokes after going over a bump during a ride. The speed sensor periodically cuts out, then restarts after a minute or 2. Overall, I am dissapointed.

4 Stars roduct is super
This product has a clean display, works very well. Only gripe is that the rotating magnet(that is fixed to the spokes) has to be very close to the sensor that is attached to the front fork. It cant be more than 5 mm at the most. the specified 20 mm is imaginary. wont work.

But otherwise, the product is a great buy. no regrets.

1 Star Invest in something better – this doesn’t last!
I was looking for a wireless computer with cadence, an easy to read display and easy to use while riding. This did pretty well at first. I got “blank outs” on speed and distance every few miles, but they didn’t last more than a minute or so. The computer then “guesses” at the distance missed and your distance suddenly increases. This adds up over time to an inaccurate reading on a long ride. I was slightly irritated with this quality, but lived with it. Now 7 months after I got it, it’s got a mind of it’s own. It works perfectly for a while, and then can’t find the speed or distance (but can do cadence!) So on a 20 mile ride I’ll come home with it reading 4.8 miles. (Yes, I’ve replaced the batteries, no change.) The odometer reads 35,182 (that happened after I passed the 1,000 mile mark). It’s so irritating and frustrating now, that I just use it as a clock and will be looking for a longer lasting replacement. You get what you pay for. Invest wisely.

1 Star The bad reviews are true
Well, you get what you pay for.

After reading the reviews and seeing how this is supposed to be mounted I made extra sure to get an industrial strength double sided tape and mounted the unit.

It lasted 3 rides, then I hit a bump and the unit flew of my bike, after it hit my spokes.

Do not purchase this product.

5 Stars Sigma BC1606L with rear wheel harness
I just bought this item. It includes two harnesses. One for the front wheel and one for the rear wheel. It also includes the optional wired sensor to measure cadence and of course the bike computer itself. I am please with the unit so far and I installed it on the rear wheel of my bike that is on a Kurt Kenetic trainer. It works well for both speed and cadence. Now I can judge the kind of effort I am using and can up my game as time goes on. The only problem was that the install instructions leave a lot to be desired. I figured it out but it took about an hour for the install. The package also does not come with a list of items included in the box either which was a little frustrating. These were not really big problems but Sigma should address them for the future. I recommend this unit to anybody who wants a bike computer with a wire rear wheel sensor.

5 Stars Works Great!
We’ve had this a few weeks. I purchased for my wife’s bike so she could use it with the indoor trainer. This was one of the cheapest ones I could find that would work for the rear wheel. It also has the cadence monitor. Pretty easy to understand, not too difficult to set-up. It has a back-light on it, so once you press a button it will light up for a few seconds. Probably could have used a couple more zip-ties with it, but I had some.
