Strange "crack" in my stem/bar combo...(7 posts)

Strange "crack" in my stem/bar combo...ronvermeeren
Aug 17, 2002 9:00 AM

This year i build a new race bike. I bought following stuff
ITM Millennium SUPER OVER BAR and a 3ttt XL Zepp stem. The headset i use is one from chris king (1' by the way). When i ride after a period of time my stem (i don't be sure it is the stem) cracks/ticks, and this drives me really crazy. The headset is tightened OK. Does anyone have similar problems with this stem?

Thx for any support,

Is the steerer tube carbon on your fork?

Your stem has been recalled. It's requires longer bolts for the face plate. The current bolts are too short and risk working them selves loose or simply sheer off from the threads. It's a possibility that's where the noise is coming from. You should be able to get replacement bolts from your LBS or you can simply get some 8.8 steel bolts from the hardware store (take into account it's metric).

You may want to check, but I believe that the ZEPP stem may have been recalled.

I had a similar noise. I was using the flipped Zepp stem to avoid too many spacers and obtain the necessary handlebar height to make the ride comfortable.

I switched to the ITM stem, heavier,but made for the ITM bar. I added about 1cm of spacers to compensate for the stem height change.

The additional spacers did not effect the flex of the fork, and the creak disappeared. Also, I think it looks better with a stem that parallels the top tube, rather than the 10 degree rise of the Zepp.
