Question: Good day does this have a setting to calculate speed and distance for a 26' MTB
Document: The LED display is very readable (during the day)a number of Time tools;Trip miles, over all odometer, speed avg,  highest speed and Time.I would of given it a 5 * but the buttons are so large top and bottom you need to be careful when setting it up the first time.
Why on earth those setting don't reset together is beyond me. I'd be happy if the trip distance/trip time reset together and the max speed/average speed reset together.
I bought this for my mtb because it was simple and inexpensive. I just need reliable and accurate speed and overall ride avg data. This unit was easy to install and performs well enough.I do have a few things I dislike. I prefer to keep the data field below the speed on "trip time". After setting this though, this unit will later reset this field to the trip distance. Its annoying to have to switch it back. Its also tedious to reset the fields for a new ride.
I bought the Sigma originally for my mountain bike as a curiosity of how fast I was going. Its easy to use, easy to program, and easy to read. When I invested in my first road bike, I used to Sigma to accurately keep track of speed and distance for all of my training. when I started to take cycling serious, I started to get into GPS and tracking my rides more carefully using advanced software.Those fancy gadgets stay home on race day.
good computer, it does what it is meant to do. only thing i wish is it would have a back light. other than that i would recommend it to anyone that needs to know how fast is going, the avg speed , distance and clock.
I know there are very sophisticated speedometers, however I needed something simple to install and use.Assembly and initial definitions were very easy. Basically you track 4 parameters, and can reset each individually (distance, time, average speed and highest speed). Additionally there is an odometer which accrues the total distance and time.Fair price and looks like good quality for what it worth.
The features I wanted from a bicycle computer:* Clock (to tell how late I am to work)* Current speed* Record speed* Trip information (time, distance, avg speed), so I can improve on my last commute* Weather-proof* Easy removal in case of heavy rain or leaving bike outside* Awesome looks to complement my awesome ride. Good brand.
I've had Cateye cycle speedometers on two of my bikes for years and purchased the Sigma BC 1009 based on the good reviews. So far I'm quite happy. I really like the stem mount option and have not had any issues with the connection point which seems to be a recurring problem with all the cateye speedometers I've owned ( I often have to wiggle the units to get them to start reading speed  + distance when i begin my ride).
I purchased two for my wife and I. It is a wired version which I prefer as opposed to a wireless. It represents a very good value. My only complaint is that they seem inaccurate. I followed the provided table to set them up for our tire sizes and they seem to read about 20~25% higher for speed, and I assume distance also. I checked with GPS and it consistently read about 2 mph higher in the 8 to 10 mph range.
This bike computer works very well.I find setting a goal and watching my average speed greatly improves my workout.
Answer: yes
