Want to install a wired computer on my TT. As far as function the standard stuff is OK but I also need average speed. What is most importance is size, I have a specific place I want to tuck this and would like the smallest possible (height/width) computer. What do you guys think is best?

Sigma BC 1009.

WW, do you know what the dimensions of this unit are?

waynesworld

Not offhand. You might be able to find them somewhere though. It seems small to me, and works well so far (~200 miles). I have mine mounted on my stem. It's also cheap. Last I checked, it was less than $20 on Amazon.

BTW, I just did a quick search, and did not find dimensions. I'm at work, and I rode a different bike in.

Cateye Strada is 46.5 X31.0 X16.0mm. I'm not sure they still make a wired version.

How much money you wanna spend and how hung up are you on "the best?"
I have a Cheapy China model that came in under $10 that gives average speed, along with the usual other info. It is 50mm x 45mm.
You might wanna hide it, though, so people wont see it sullying your Quintana Roo. Mine has been on my commuter now for a long time and is still going strong.

Heaven forbid

This is the deal: I use my iPod touch as my cyclocomputer for training, I mount it using an armband strung between my aerobars. Works great. However, I have decided to go with a Profile Aerodrink for races thus taking away my iPod real estate. I have gotten used to having a computer giving me real and ave speed during races to keep me focused. So, I think that a dedicated computer that I install specifically for races is the way to go. Wired is probably best as they are lighter and cheaper. But there is only a limited amount of real estate in the cockpit once I put the aerodrink in there so I need to be concerned with size.
Another question: I like the sigma mounting system with the O-rings as this will facilitate easy installation/de-installation. I'm assuming this really works,, right? In looking at the available models, the BC1609 has an auto On/Off feature. This is attractive as I will not have to remember to turn the thing on during T1. I have this right?

The O-rings worked great for me so far. I did have to buy another large O-ring at the hardware store, though, because I have a fat fork and an oversize stem. It comes with a large and a small one.

I don't know about the 'auto on/off' feature. I mean, my 1009 turns itself on when the wheel starts moving, and eventually turns itself off too, though it still displays the time and "BC 1009" when off.

It measures approximately 45HX42Wx14D, computer only - not the mount. I just measured mine in the garage, and that's what I got.

Oh, okay. I dont have an iPhone nor the money to keep one running - hell, the stuff you guys are talking is mostly Greek to me, anyway. But Im learning!

Sooooo, I'll leave ya and bow out. Best of luck and ride it like you stole it, folks.
Peace out.

The Sigma Sport mounting system with the "O" rings works fine and can be used on the bars or stem. You might have to fiddle around with the sensor positioning when you re-install it, but that would be the case for any computer. The only problem I've seen with the Sigma computers is that the magnet is not very strong. You might want to spend a few dollars on a stronger magnet.
