What bottom braket came on your Ace?

troubleshooting a creak on an aluminum frame is very difficult to do... it resonates the sound severely.
before diving in make sure everything is tight at the wheel. my skewers often don't clamp hard enough being 32g for the set so i hear a creak there. and work your way up from the basics.

if it comes down to the BB, you need to see if the bearing cups are external to the shell or internal.
the second picture in the gallery on pricepoint shows it clearly, as a howizter not a giga pipe.

Thanks for replying. I guess I will start at the wheel and work my way up.

A creak can easily just be a seatpost, stick some grease on it then see what happens. Or Drip some lubricant on the bushings at all the pivots on the frame.

Howitzer is for Holzfeller cranks

highdell, look at the pictures in the gallery, its not the giga in the pictures...

Regardless, the same wrench will work on all EXT. TruVativ BBs AFIK

the giga pipe uses this tool:
