[QUOTE=Gnosis;15849805]When my cousin purchased his 29er hardtail he also had the LBS install a new Bontrager speedometer (around $49 as I recollect). While it worked well enough, its button usage wasn’t intuitive and it was far too easy to accidentally reset the wheel size. For that reason alone, I’d likely not purchase a Bontrager speedometer, but it also perpetually indicated the actual time (hence never shut completely off when not in use), which meant its battery would be depleted sooner.

My numerous cheapy 12-function Schwinn speedometers have worked fine for the last 2+ years now and they were only $13.00 each at Walmart. I only require the following functions:

Trip Distance
Max Speed
Average Speed
Trip Time
Actual Time
Odometer

My cheapy Schwinn speedometer allows me to re-enter the odometer reading if the battery fails or I have to perform a reset to re-enter a different tire diameter.

In the picture I provided, I temporarily attached my Schwinn 12-function speedometer to monitor the rear wheel of my Trek 2.1 road bike, as I wanted to see how fast I could crank the rear wheel by hand in its highest 50/11 gearing with the bike flipped upside down on its handlebars and seat. With the correct tire diameter entered, you can see that I achieved 74.6 MPH. I had also just balanced the rear wheel with its 700 x 28 tires installed, so I wanted to see how smooth it was when cranked up as fast as possible. It was very smooth, but I wouldn’t want to get my fingers, hands, or arms caught in its spokes at that speed, as it would have no problem severing them. The wind generated by the rear wheel was blowing papers off my table located several feet away!

I recently bought an Iron Horse computer,same company as Schwinn.Easy to program,easy to read ,large numbers.No cadence but features such as temperature and a light for nite rides.20.00 bucks.I had nothing but problems with the cateye strada afterabout 5months.
