Wired Up

I finally picked up a computer for my bike. After much searching, I settled on the Blackburn Delphi 4.0. It’s a pretty slick piece of machinery. The thing weighs about an ounce. It’s singularly unique, sculptured in design, hand-crafted in Switzerland and water-resistant to three atmospheres. It tells time simultaneously in Monte Carlo, Beverly Hills, London, Paris, Rome and Gstaad. More importantly, I get speed, cadence, time, average speed and even altitude if I can figure out how to set the altimeter.
It was a monumental nightmare to get my bike wired up. The instructions were for shit, which is problematic, because it’s amazingly complicated. First I had to get the battery in and that was no easy chore. Then I had to mount the magnet on the front spoke and the wireless transmitter on the front fork. The cadence magnet has to be mounted on the left crank with the cadence sensor on the left chain stay. Then I had to run a wire under the bottom bracket and along the down tube and mount the actual computer on the handle bars, which, of course, I did backwards the first time because I’m an idiot.
The first ride out, I wasn’t getting any readings and after 30 minutes of wrestling with the thing, I was almost ready to give up. The problem was that the magnets were too far apart from the sensors. Both sets of magnets and sensor have to be between 1 and 3mm apart, which is a little tricky with fat fingers like mine. I moved everything closer together, and bingo, I started to get data. Very cool.
The sun was setting, but I needed to get out on the bike to test it out. Here’s the deal on my first recorded ride. I rode from my place up Adeline & Shattuck towards the Berkeley campus, up to Elmwood and back down Alcatraz to my house. The total mileage was 5.54 which I managed in 25 minutes and 30 seconds at an average speed of 12.9 MPH. My cadence was 54 and I hit a top speed of 28 MPH cranking down Alcatraz. Short ride, but it was fun and I needed to stretch my legs before my first 50 miler tomorrow.
