Creaky Bottom Bracket

I have a new bike (Cannondale 800 Tri) and I notice that when pedaling the bottom bracket "creaks".
Is this due to the torque on the bottom bracket when pedaling? Is this normal with aluminum frames?

 

Not normal. Take back to dealer.

It would be due to the bottom bracket needing adjustment; or, improperly installed. It has nothing
to do with being aluminum. However, do note that with aluminum bikes that sound or noise "travels"
so it is hard to determine where it is coming from, sometimes. Good Luck! David Never give up, Be

I had also something 'creaking' down there when I pedaled with force (uphill). But when I stopped I
couldn't find the problem. Until I found out that one crank wasn't totaslly wrenched.

The "Cannondale creak" is more common than you might think. I've owned two Cannondales and I know a
good number of Cannondale owners. The creak seems to only happen on the higher end frames (CAD 3/4
and up). It seems to happen the most when the bike undergoes temperature changes (typically cold to
hot). I've known guys that have replaced everything possible down there but the frame and the creak
will still happen occasionally. I bought a R500 4 years ago and a R800 1 year ago, both are still
going strong (with the occasional creak) and nothing has fallen off yet.

Check your cleats and shoes. Sometimes a loose cleat creaks...

Put some plumbers tape (teflon tape) on the thread on the chainring side. Mine was making awful noises, but this fixed it in a matter of minutes.

 

after the Columbia Tri? Talk about temperature changes....
