Submitted by Geoff Duncanson a Cross Country Rider from STRATFORD, CT, USA
Date Reviewed: December 24, 2006
Favorite Trail:none yet
Duration Product Used:More than 3 years
Price Paid: $25.00
Purchased At:NashBar?
Strengths:Setup is pretty good, I agree with other reviewers that the instructions could be better translated; but with a simple computer like this one doesn't need to refer to them once you have the basics.

I like the simplicity of the rubber o-rings, granted I'm not thrashing through the woods or careening downhill where they might be alot of harms way but I've never had a problem with them.

I tend to like trail riding in the rain, and these haven't fogged up or quit working.
Weaknesses:this computer has two buttons, fore and aft of the display area. I sometimes have trouble cycling through the menus to get to the one I want and also resetting the trip time and mileage while I'm riding becuase you have to hold the secondary button in for several seconds to do so. It's probably me, but that's my only complaint.
Similar Products Used:sigma 800, sigma 1600
Bike Setup:rocky mountain stratos
Bottom Line:clear large display-shows all the important data in one screen. very reliable, I've used it now for over seven years without a problem. price is low for it's longevity.

Duration Product Used:Less than 1 month
Price Paid: $35.00
Purchased At:Mammoth - Madrid
Strengths:Simple to use - simple to set up - clear and legible under any conditions - no fiddling necessary to pull out all useful functions. A great first unit (so I thought) that will not detract from the pleasure of riding.
Weaknesses:O-rings to hold the sensor? That's a bit bold (almost lost it on day 1 because of that)
Similar Products Used:None
Bike Setup:Trek 6700 - stock.
Bottom Line:This unit could deserve top rating - if only they had thought about another way of holding the sensor. I see some reviewers mentioning they fixed their units with zip ties - and I'd love to understand how since there is no holes drilled-in for that. The o-ring that was provided with mine (42 diameter) broke on the first day of use. Pretty disappointing. Might upgrade that review when I figure out how to mount the sensor safely (if I have not changed product before that).

Price Paid: $30.00
Purchased At:Pedalon
Strengths:Sigma make the most advanced, affordable cycle computers I have ever owned. In the last 20 years I have used Avocet, Cateye, VDO, Specialized, wired and wireless. I was so impressed I have three of them, all RDS wirelss. MTB, Road + 1600 Cadence on my trainer. All are still on the original long life CR2023 cells. I particularly like the dual read out with an indicator tp show if you are + or _ average speed. Great for enduro's or 12 hour races. 2 tyre sizes can be stored for summer + winter. At last the ability to manually set the Total distance of the Odometer (so when the battery does need to be swapped you can punch in your lifetime mileage ... sweeet. No tools required, screwless design is fitted to fork and bars with large O rings

Tip+ Put a small dab of BP petroluem jelly on both terminals of the head unit and you could ride under water. No probs even in the worst driving rain.
Tip* Take the head unit off the bike when not in use which seems to prolong the Cell life. Tip# The EMF from bar mount HID lights interfere with Wireless reciever. Follow these tips and Sigma will NOT let you newbies down. That's a promise ...
Weaknesses:Buttons can be a bit sticky + fiddly at speed.

Duration Product Used:1 Year
Price Paid: $18.00
Purchased At:REI
Strengths:Excellent display, easy to use, good price
Weaknesses:Handlebar bracket has cracked twice
Similar Products Used:None
Bike Setup:Specialized Stumpjumper
Bottom Line:I decided to try out a computer when I bought my new bike and went with the Sigma 1200. As for the computer itself, it has worked flawlessly. I like the display better than the Cateye computers. It's easy to read and moving between modes is no problem. The rubber O-rings that hold the handlebar bracket and the fork sensor have given me no problems at all.

My only problem has been with the handlebar mounting bracket. I like the fact that it's small and has a low profile on the bar, but I've cracked it twice on crashes. I also tore the wire once; it must have snagged on a branch. Each time it broke, however, I was given a free replacement bracket, either by Sigma or REI.

Despite the bracket problems, the computer itself has worked just fine and I've been happy with the product overall.

Favorite Trail:Anywhere
Duration Product Used:3 months
Price Paid: $25.00
Purchased At:Pecco's
Strengths:Simple design, good interface, availability of wireless upgrade
Weaknesses:Strange instruction manual, but well detailed
Similar Products Used:Numerous computers w/o cadence feature
Bike Setup:Specialized Stumpjumper 2004
Bottom Line:I had been using a Cateye computer on my Rocky Mountain, and I couldn't stand it's strange interface. I picked up this computer after comparing the various models on display (love the display, by the way, with a small wheel mounted. It allows the user to spin the wheel to see how well each function is accessed and displayed by the computer.)

I was also tired of cables getting torn, pulled out, twisted and so forth and sprang for the wireless upgrade kit. I like how the wireless kit integrates, and although I ran into a couple issues during the installation (for a while, I couldn't undertand why the computer would not pick up the signal from my spinning wheel, until out of frustration, I gave the wheel a spin in the opposite direction and the computer registered. I had the wireless received backwards...) Finally got everything mounted correctly (with the wireless receiver mounted facing the front of my fork). And so far, I have found this computer to be very accurate.

I have read a few reviews that indicated that some issues were encountered with rain and humidity, and I can state that I have had no problems so far in this regard. Great computer, with a very straightforward interface and controls.

Favorite Trail:Any
Duration Product Used:3 months
Price Paid: $23.00
Purchased At:Aerostich.com
Strengths:Price, accuracy, functions, weatherproof
Weaknesses:Can't store unique data for multiple wheel sizes
Similar Products Used:None
Bike Setup:Triumph TT600 (motorcycle); Trek 3700
Bottom Line:I actually bought this to replace the failed digital speedometer on my motorcycle. At $23 it was a lot cheaper than the Triumph parts. Contrary to claims by the "experts" at the local bicycle shop, I've found the BC1200 to be accurate up into triple-digit (MPH) speeds (closed course only; professional rider shown; don't try this at home; read your owners manual; don't drink and ride; etc. ;-). Supposedly most bicycle computers aren't accurate above ~40mph or so, but that's not the case with the BC1200.

The unit can be programmed for two wheel sizes, and since I have an extra mounting kit I was hoping that I could easily use it on both my motorcycle and mountain bike. I can, and the BC1200 can store two wheel sizes so switching back and forth takes mere seconds. However, all of the riding data (max speed, avg. speed, trip meter, total odometer, etc.) is shared by both wheel sizes. I was hoping that on Wheel 1 I could keep the running odo total accurate for the motorcycle, while running a unique odo total on Wheel 2 for my bicycle. Alas, it doesn't work this way.

Other than this admittedly obscure problem, it's been great so far.

Duration Product Used:More than 3 years
Price Paid: $16.00
Purchased At:Tesco's - Budapest, Hungary (July 1997)
Strengths:Cost me a mere $20/CAN back in 1997. It still works and only needs new batteries once a year.
Weaknesses:The comp. itself nothing, I got the wireless upgrade for it and it died a few Km's into my 2nd ride with it.
Similar Products Used:Vetta C-10, Sigma Sport BC1400, Planet Bike Protege 9.0.
Bike Setup:2001 Trek Fuel 90 Disk/stock - tires changed for slicks.
1996 GT Ricochet/stock - tires changed for slicks.
Bottom Line:After 8yrs of useage, changing the batteries only six times from 1997-2005(1 pair/yr.) and 1 cordless upgrade that didn't work on the 2nd ride it was well worth the $20.
Bottom Line: Best money spent on a bike comp. to date.

Strengths:One cheap battery last long, compatibile to all sigma, cadence, functions, dual bike, set up start total distance for each bike. Good value - compared to others availabel.
Weaknesses:rain no proff, can't be disassembled (so hard to dry it).
Can't set total time. Lost data in rain many times.
Similar Products Used:BC1400 (2000), BC1600 (2003)
Bike Setup:2 MTBs (one alivio complete no suspension & cadence, the other deore complete)
Bottom Line:Seems that SigmaSport reduces functions on new models. My friend has BC1200 (1996, 2 batteries) with EL display but it stopped (rain, fall appart), my computer (year 1998) lost EL but has just 1 batterie and is small. Later models (BC1400) has the same functions, added for me useless funct. name in 7 languages. This years BC1600 has the same f. as BC1400.
Worked fine for about 4 years. I changed battery +2 times in that time, but this year rain kill it and now it neeeds batteries. Seems that it is time for new computer.
This years models are not back compatibile.

Bottom Line:It's a great computer. I haven't had any problems with the installation or the mounting hardware, although I did replace the rubber bands on the wireless kit with zip ties. It works great, was easy to set up and works for 2 bikes. Another reviewer mentioned that you had to individually reset each display after the ride, that's false. All you do is hold the top button and the bottom right button in for 2 seconds and it resets for the next ride. Also it was very easy to enter the wheel sizes.

It works great (apart from the cadence kit) and I've never experienced any problems with this model after more than 3 years in all kinds of weather (mostly bad - I live in Northern Europe) and more than 30000 kilometres. The rubber bands never gave me any problems, the buttons never malfunctioned and the unit has remained 100% water tight. The cadence kit is joke though - the connectors are of a poor quality. The best option is in my opinion to forget about the cadence option and buy the Sigma BC800. Nor do I see any reason to go wireless as the wired system works just fine!

Strengths:Small size, 12 functions.
Weaknesses:Ruber bands to hold base and sensors. Mine have been already broken (c'mon... this computer is used in a bicycle, not inside a car). Computer conectors very weak. Set up complicated. Bottoms? Maybe nails!!!
Similar Products Used:None
Bike Setup:Cannondale F400, XT drivetrain, Avid Arch Rival 50 brakes
Bottom Line:This computer has a good look, but after you try to set it up, you will find several problems in order to set the wheel diameter and magnet position in the wheel. The buttoms are too hard to be used while riding. The conectors are so weak that if you are not very careful you will bend them ruining the base. The ruber bands are easy to mount, but after a season riding in the elements, you will find how easy they break. Sorry, but this product deserves the worst of the qualifications.

Similar Products Used:Cateye, Vetta
Bottom Line:I bought this computer to replace my cateye enduro that has been running 3 years on my road bike. With the sigma, the first thing I noticed was the poor quality of the sensors mountings. They are quick-release, but that happened to be an every-time-released! The cadence sensor is conected with an small plug on the computer base, and needless to say, these conectors did not stay in.
I was already very sorry for this choice I made, and then, the screen becames blacks when exposed to sunlight even while riding at 30mph+ speeds, and when I got my third rain, the computer screen has flooded!!
That was enough! I went to my LBS, and luckly he replaced it for me with a cateye enduro 2. I lost $10, but that's better than losing the whole $40 of the sigma junk

I once had a Cateye Mity 2 that reset itself every time you accidentally touched it, and killed all the data for the ride.
I had a Secialized that went haywire every time I went through a shallow puddle.

My other bikes have Sigma 800's which have been more reliable than others I've used. For this bike I wanted cadence, to I got the 1200 plus cadence wire. It's excellent. Easy to read and easy to switch functions. I get constant speed and plus/ minus average and time or distance on one screen - that's all I need.
The rubber band fittings are very europoean, and it's easy to move computer by using 2-sided tape.

This computer does all I want - a good road computer.
If you're a mountain biker you should be using a heavy duty model like the Sigma TARGA.

A few words of caution: I bought the wireless mount and the computer broke off the handlebar mount during a crash on the first ride. It happened to be a race and when I passed the crash site on the next lap I found my computer laying in the grass. Apparently, there are two tabs that stick up and look the computer in place. The force of the crash broke the tabs and sent the computer flying. Didn't realize it was gone till a few minutes later. Good thing I found it or my review would have been real bad.

Since the crash I just use it on my road bike where it is fine.

Bottom Line:If you plan on never getting your computer wet, by all means this is the one for you. I rode once in the rain with it and it hasn't been the same since. Even sweat dripping on it causes it to go blank. It takes a week or more to dry out, and then some of the LCD's don't work (is that a 7? 4? 9?) Unusable. 3 chilis for function, 1 overall because I have to buy another one.

Favorite Trail:Flume Trail, NV
Duration Product Used:2 Years
Strengths:Easy to install. Easy to use. Works flawlessly. Cadence kit. Great Display. Reliable.
Weaknesses:Wireless transmitter kit.
Similar Products Used:Trek, Vetta
Bike Setup:Trek 7000 Customized Race Bike. Haro DX2 Full Suspension Customized Bike. Raleigh R600 Road Bike.
Bottom Line:This is a great computer. It was easy to install and the functions are intuitive and easy to scroll through. My family owns 5 BC1200's which we use on 9 different bikes. On our road bikes, the cadence kit is easy to install and works great. None of our 5 units has ever given us any trouble in the 2 years we've been using them. My only complaint is the wireless kit, which is an entirely different product, but works with the BC1200. It's unreliable, has a crappy mounting (think rubber band)sytem and is easy to loose.

Date Reviewed: June 11, 2000
Duration Product Used:2 Years
Strengths:Easy to use, fairly simple to install, illumination
Weaknesses:the sensor doesn't work as it should, a weak handlebar attachment
Similar Products Used:none
Bike Setup:Scott Navajo
Bottom Line:I bought this computer cuz' it was the best money could buy (in my local bikeshop). It worked as it should (on my old bike), but as i switched, i had problems fastening the sensor on my fork. There was a to wide a gap between the sensor and the magnet. The computer didn't show any movement. I somehow fixed the problem and the computer worked (after i almost went amok because of it). It worked for some time, but after about half a year died completely - everything worked except that it told me that i wasn't moving. The computer was just an ornament on my bike.
In the good old times, whet the computer worked, i was very satisfied. There were occasional glitches, but they were rare (i was standing still and still had the velocity of 50 km/h).
I once tore the wires that connect the computer with the sensor - no big deal. I only needed a screwdriver and patience for the repair. Cherioo for the simplicity.
The handlebar attachment piece is to weak, cuz' i lost the computer after a crash.

Date Reviewed: May 16, 2000
Duration Product Used:1 Year
Strengths:Great customer support, large readout in the display. Two wheel sizes with total for both sizes. Cadence capability without having to have cadence hooked up all of the time
Weaknesses:On two separate occasions it leaked in extremely rainy conditions. Instructions a little vague more information needed.
Similar Products Used:Cateye, Sigma 1100
Bike Setup:GT Zaskar, SID Race, Full XTR Group, Race Face stem Easton Bar, Titec BarEnds, Michelin Tires, Mavic Rims
Bottom Line:I have owned three of these things and have never had the problem experienced with the speeds although I have talked to people that have had problems. I owned two that leaked in extreme rainy road conditions both of which Sigma replaced without incident. Customer service was very helpful and willing to do whatever I needed to have satisfaction. Have not had any difficulties with calibration, I check it quite frequently and the model I am using probably has about 4000 miles on it with no trouble. Have recommended this computer to other people who have had some troubles. This computer is very useful for MTB riders who use road riding as a training tool because of the two wheel sizes you are able to switch back and forth with relative ease. The total distance for both sizes is very helpful for logging your total miles.

Duration Product Used:3 months
Strengths:Accurate when it works.
Weaknesses:Reliability, instructions.
Similar Products Used:Trek basic, Vetta C-15
Bike Setup:Lemond Zurich (road bike)
Bottom Line:The instructions are hard to understand (only images, no text). It worked flawlessly for the first 6 weeks (600 miles). Then the speed occasionally started to go wild, becoming completely random and then returning to normal. It even registered a maximum speed of 172 km/h!!! I checked the connections, the magnet, everything. Never got problem with the other products mentioned above (and used for years). Bottom line: unreliable and therefore, useless.

Favorite Trail:the local loop
Duration Product Used:Less than 1 month
Strengths:Ease of use, large 2 function display, ability to use on 2 different bikes, no tool mounting.
Weaknesses:Installation(on fork), vague instructions
Similar Products Used:Avenir, Cateye
Bike Setup:Mongoose RX5.5 road bike with: carbon aero fork, Shimano 105 gruppo, clipless pedals, Mavic rims, Hutchinson and Michelin tires
Bottom Line:I needed a new computer and since I liked its features and its two-bike adaptabilty, the Sigma was choice for me. The enclosed instruction manual was fairly vague, mainly just pictures, with little written descriptions to go along with them.

After studying the diagrams for a few moments, I had little trouble installing the computer except for one area: The Fork. The supplied O-ring was almost too small to fit. I had to start at the fork's dropouts and inch the sensor mount up from there, fairly tedious, but it was the only way I could install it without risking tearing the ring. Perhaps Sigma could provide a larger O-ring to accomodate the bladed-aero forks that many road bikes have nowadays.

Aside from the instructions and the troublesome fork fit, all else has been quite good. The dislpay is easily viewed from the saddle and the buttons are simple to use, even with gloved fingers. I plan on adding the cadence feature soon and add a mounting kit to my mountain bike as well.

Since it is fairly new, battery usage hasn't come up yet, so I will see how long the first one lasts. I have had no problem with the magnet or sensor, the computer has connected perfectly since day one. Overall very nice, and I'm pleased so far.

Duration Product Used:Less than 1 month
Strengths:Nice readout and fairly simple to use.
Weaknesses:Using visual instructions for installation are ok, I could follow those but I would like more written instructions on how to use it.
Similar Products Used:None.
Bike Setup:Cannodale road frame.
Bottom Line:I just bought it so too soon to give a practical review but I thought the instructions worthy of immediate comment. I can appreciate cramming 9 different languages on one sheet but get real. Sigma needs to have detailed written instructions as well as visual instructions. I got the thing installed ok but I am basically have to figure out how to use it on my own.

4 chilis because the price is right. 1 chili for the instructions.
