Kestrel RT700 creak, Sigma 1606 issues, Batteries

It's always something with a bike, isn't it? Something wears out, or goes out of adjustment. I love my Kestrel RT700 but I've had a couple of vexing issues that aren't the frames fault, but annoying none the less.

Hear now my tales of woe concerning a creak and a speedometer.

Part 1
Those forced to ride near me lately have commented that, though my bike is a thing of art and beauty, the very loud creaking that happens whenever I stand is not art, nor beauty, but downright annoying. Really annoying. Loudly annoying. Imagine how I feel.

I have done everything I can think of. I've put lube on the dropouts, the seat post, the seat post binding bolt, the skewers, the stem bolts for the bars, the stem bolts to the steerer tube, the steerer tube bolt.

I hired a pro who took apart the bottom bracket. He was sure the sound was drive train related. We messed with the dérailleur. I rode past him over and over. We couldn't find it.

In a flash of smartatude I thought "Cleats!" and greased and tightened them.... nope. It wasn't the pedals either.

"Maybe it's the hub!" said I, but no, not the hub or, or gears. I swapped wheels and still had that creak creak creak..

Yesterday in the Wine Country Century my BikeForums.net fried Pete (Taxi777) casually said "It's the headset. I had that. You need to grease every washer, then put it back together" and then rode rode off to flirt with someone.

He was like superman ... a "My work here is done" sorta thing.

So the next morning morning, after Tricia and I did a slow 20 mile recovery ride with lots of creaking I did as the Pete suggested -- greased the washers and spacers.

Guess what? Yep.

My map-ignoring, photo-bombing, mad descending ride leader has, with no effort, solved a problem has been vexing the finest minds in the bicycling industry and brought us all one step closer to world peace.

Part 2
I really like my Sigma 1606 Wireless computer. I like the display size, the buttons, and the fact that it doesn't lose info when you swap batteries. But it's been giving me problems. The sensor mount doesn't love my fork. It has twice vibrated askew, been caught in the spokes and ripped off the bike.
Now my computer doesn't sync with it any more. Then it stopped syncing with the cadence sensor. Then it started acting all weird. I guess dropping the head unit and snapping off the front and gluing it back together hasn't really helped it much.

The problem with wireless is that when it fails you are never sure where the problem is; the sensor/transmitter or the head unit.

I've now mounted the wheel sensor on the left fork, and faced it forward. I built up the mount so maybe it won't move, and even if it does the spokes will knock it back and not grab it and tear it off.

I've also replaced all the computer and sensor batteries. It all appears to be working now. At this small moment. Here's hoping all my voodoo pays off.

Part 3
I still need to make the Minty Boost battery booster for my Garmin 305. The battery in it is good for about 9-10 hours. If I use this on the Davis Double I'll need it to last longer than that. Here's hoping I can remember how to solder.

Does this stuff ever end? At least everything seems to be working correctly -- maybe perfectly -- right now.
