Hi,
SO after riding at Motoland in Casa Grande, AZ, I found that I had excessive play in my steering. Grrrr...I was afraid it was a bad bearing on the bottom of the steering tube had gone bad. I found that the 3 bolts that hold it in were loose and had almost 1/2" up and down play in it!!!
Anyhow, Just thought I would remind all of you to check those bolts before something bad happens.
God bless...

Good tip, I had this happen recently also. Although my stem bearing holder only has two bolts that hold it in place. One on each side of the stem bearing.

My bolts havecome before too, but I bounced off several trees even broke my steering stabilizer....so I figured that had something to do with the bolts coming loose.

Hi,
Yeah, I was really blessed cause I was working on clearing 35ft doubles right before I quit for the day, so if it came totlly off, I could have been in the hospital today! Thank God I quit when I did.
Hope you all have a great day.
God bless...

I just had the same problem. The bolts were loose and I never checked if that was the issues. I just bought a new bearing and 2 piece holder. Another $25 wasted because I assumed that was the problem.
Anyway got mine from Dave (Cannonmoto), got it in 2 days and never had to leave the house.
BTW, thanks Dave

I have one or two of those bearings in stock if needed.

I think this is more evidence that the 2 stock bearing-plate bolts are just too weak. While replacing a bent stem a while back, the bottom plates were a bit hammered out, but the 2 bolts had already stretched and started bending and loosening. I noticed that the castle nut pockets on the plates are sized to fit full 1/4" carriage bolts, but Cannondale used slightly smaller 6mms. But even with 1/4" carriage bolts that are easily available, they are really too soft for that application.
Instead, you might consider using Grade 8 Hex bolts. Here are pictures of Grade 8 fine-threaded 1/4" bolts and nylocks (avail locally), and with camlocks added for wider plate support and secure locking. You will find it's really easy to bolt from the bottom-up instead.

Look again but I think the bolts will hit the steering plate? I think you have to use a carriage bolt?
