When my Trek Navigator was getting ready to turn over 5,000 miles and before I bought a used Trek 1220 to replace it, I took a picture of all the accessories mounted on the handlebars.
From left to right:
Heart Rate monitor
Cateye Enduro Cyclometer.
Police scanner (I work at a newspaper and like to keep up with what’s happening).
NiteRider Pro-12E headlight.
Cateye Astrale cylometer with cadence. (No, the two halves of the bike don’t go at different speeds. I just wanted to be able to monitor my RPMs, so I bought the Astrale after the Enduro and never bothered to remove the old one.)
Control head for the NiteRider
AirZound II air horn, powered by a refillable air bottle.
I quickly learned that my heart rate and cadence was a better measurement of how I was doing than my speed. If I keep my heart rate in the 158 to 162 range and my cadence at about 82, I can go all day. My highest heart rate climbing a hill on a hot day was 194. It’s not uncommon for me to hit the mid-180s, but I can’t sustain that long.
The AirZound is great for chasing away charging dogs and dealing with clueless motorists. I saw one car starting to make a left turn in front of me and laid on the horn. The way the front of his car dipped down showed that he thought he was about to get nailed by an 18-wheeler. It’s also nice to be able to respond to the honks of jerks who think that you don’t belong on the road.
Wait until you see all the stuff that’s on my Trek 1220.
