 Does everything it is supposed to.....Oct 24, 2008
By Jeff Gibbons
That's it, you need to read the fairly straightforward manual and install it correctly, but the bang for the buck here is teriffic. The wire is unobtrusive and I guess that the "unwired" version would have two batteries; one in the sending unit that seems to me would take more power and maybe go out quicker. My guess only.
If you have a bike path with mileage markers you can tweak the unit to your bike by changing the wheel size that you input in it, making it very accurate.
I find its more fun to know your speed, distance, average speed, etc., it gives you something to shoot for on your next ride. Plus it weighs about nothing; you could wear thinner socks and make up for it.
Have fun.

Cool little bike computer, Installation can be tricky.Mar 07, 2009
By TerryK
This was my first bike computer and I'm happy with my choice. It does everything it's designed to do quite well. There is a little bit of a learning curve as far as navigating through its options/functions but once you get it there no issue at all.
Installation was a little more involved then I thought it would be and I am very mechanically inclined. Nothing your average DIY'r can't handle just some interesting things to deal with like placement of the magnet and dealing with, for my install anyway, an overly long sensor wire. You have to get a little creative to keep the wire secured and out of the way of moving parts.
The first mount/sensor wire assembly that I received with the computer was faulty. After much remounting and head scratching I called the US contact for Sigma. He was very helpful and told me that while every computer is tested for operation the mount and wire assembly are not. He sent out a replacement mount/wire (at no cost) and once I swapped it out the computer worked perfectly. I don't I think I broke the wire on the first one as I was extremely careful with the installation but just in case, be careful as it is a small wire and you have to make several turns and twists to get installed.
The manual is one of those international mutli-language picture books. I hate them but if you spend some time deciphering it before you start you can get it done. As one of the other reviewers stated, getting you tire size right is critical to the accuracy of the computer. So spend a few extra minutes here and actually measure the circumference. Using the chart in the manual will get you close but not exact.
Once installed the combination of the double sided tape and rubber ring used to mount the computer to the stem or handlebars is actually quite secure. I have no fear of it coming off in normal use. A rubber ring is also used to mount the wheel magnet sensor to the fork. No tape is used here, probably to allow easier adjusting but doesn't feel quite as secure because of this. I've had no problem but now that I have it positioned properly I may add some d/s tape or a wire tie to lock it in place. The spoke magnet locks on very securely but follow the instructions closely on this part.
I really like this product and the customer service was excellent. If it was stolen or lost I would by another immediately. Have fun with it.

Sigma does it rightJan 24, 2008
By EC Hollis

I've been using Sigma bike computers for about 5 years now. I buy the wired, less expensive ones that only supply the basics (Speed, Ave. Speed, ODO, Trip ODO, Time)and then buy a new one when a wire breaks or the battery dies. This model is a good one except it doesn't calculate average speed (which is think is dumb). I installed it on my beater bike and am purchasing another one to install on my primary bike. It will be a Sigma. I like Sigma and they're intuitive to use.

Can't beat it for the priceNov 17, 2007
By Nathaniel T. Pond
"Nathan"
I bought this a few months ago and used it for about a month before it broke. I think the break was my fault. When I installed it I probably didn't leave enough slack, and during one of my mountain bike rides the wire pulled out of the base. I've since replaced it with a wireless cateye.
Installation was pretty easy, just make sure you leave enough slack.
The functions were great! The screen was nice and everythign was easy to read. I did have a few problems with accuracy, it would consistently report 1.08 miles for every mile I rode. That wasn't a huge deal for me, but is worth noting.

Beautiful simplicityMar 18, 2008
By R. martin
Very easy to install and set for wheel size. The reset function is wonderful. Taking the works off for security is a simple twist and it is off. Have not checked it against the odometer in my car but I think it is very accurate. I use it in the auto mode which cycles through the five displays and this suits me best. A great product for the money if you have no need for more functions. The instructions were, again, simple and easily understood by me; not the brightest bulb on the tree for dealing with technology. I don't know how it will hold up in the long haul because I have not had it long. Also can't speak for weather resistance and saw no claim for that anyplace on the web.
