Well some of you are going to laugh, but I solved my crank problem.
For better or worse, I own 4 bikes.
1. A carbon Motobecane is basically a loaner bike and used on the trainer prior to TTs. Decent components, but it started creaking when heavy force is applied...only happens under certain conditions. Bike shop can't fix it, says it's not the crank or bottom bracket. I could dump $200+ bucks into shipping back to motobecane to fix or replace the frame. Of course they could point fingers back at a component or say they don't see anything wrong and I out $200 bucks in two way shipping. Even if it is fixed, I have a bike worth $500. So at this point spending $200 bucks to hopefully net $300 isn't a great idea. Eventually it will be a good bike for my girlfriend's son or mine. This bike has a carbon FSA SLK compact crank (50-34) that I like (assuming it isn't the source of the creak).
2. A Trek Equonix TT bike. Basically got the bike for free and bought a Zipp disc and 404 wheelset. Fast and fits perfect. I really like this bike but the Bontrager carbon crank has always been flexy. I swap out the big chain ring for a Shimano ultregra chain and this helped with the shifting, but I'm pretty sure I'm losing some wattage here.
3. A Cervelo Dura-Ace R3. Thought I got a good deal at the time on a nice used bike. Rode it a few times and was very happy with the performance. It's light and stiff and built for climbing. It came with a dura ace 53-40 crank.
4. A Cervelo SLC (now called an S2). This bike retailed for over $5K and I picked it up new for $3200. Best bike I've ever ridden. Fast, aero, and stiff. Rode the Blue Ridge Parkway and several races last year with it and was extremely pleased. Came with an FSA SLK standard crank which I moved over to the R# and replaced with the dura ace crank.
Well the original plan when I bought the SLC was to sell the R3 for what I paid or a small loss and still be ahead of the game. I've always done well moving things I've bought and sold previously. Didn't count on the economic meltdown and I haven't been able to move it for close to want I want. I could probably part it out but really don't want to hassle with that. My other fear is that if I sell it at a big loss, I'll wreck the SLC in a crash and end up buying having to buy another used bike that i have no history on and not equipped the way I like. As a result, I've decided to put a compact crank on the R3 and use it in the mountains where I spend a good bit of time riding. I've riden the SLC in the mountains alot last year, but at my weight the compact would make this much more enjoyable and allow me to tackle 20%+ grades without as much wear and tear on my knees/legs. The R3 is more comfort/climbing built while the SLC is more aero/race built. The problem with just putting a compact on the SLC is that I'll spin out of the gearing in some of the local races in the flatlands.
Well I stumbled across this solution to my issues.

This crank will go on my Trek TT bike. I should gain some race benefit from the stiffness, aero characteristics, and ceramic bottom bracket. The Bonteger crank on the Trek TT bike will be moved to the Motobecane. This should help me isolated the creaking as a crank or frame issue without any further investment. The FSA SLK compact crack will move from the Motobecane to the R3 giving me the perfect climbing/comfort bike for the moutains. It will probably make the bike more saleable if I come across someone looking to buy at a reasonable price.
Yeah, I've got a lot tied up in bikes. But at 300 hours a year or so on the bike, I want to enjoy the time to the fullest. My son and girlfriend's son have also taken an interest in riding so hopefully it's a hobby I'll be enjoying with them for a long time. I've also found out after a high speed descent death wobble on the Motobecane that inferior equipment is the way to go.
