This looks like what I've got: http://www.universalcycles.com/shopp...6&category=100
This is style I'm considering replacing it with: http://www.universalcycles.com/shopp...9&category=100
Any concerns I should have before making the switch? Bike is an Argon Gallium Pro with an FSA integrated headset.
Also, will carbon assembly paste help keep the tension set?
I have the exact same plug, and (had
, I hope) the exact same problem. I tried carbon assembly paste on the plug without success - using paste on the stem-steerer interface did help a little but didn't completely fix it. Mostly assembly paste inside the steerer just made it a bear to loosen the expander to re-seat it, but didn't stop it slipping.
Just last weekend I gave up faffing around with it - I cleaned the steerer tube out with soapy water, cleaned the plug, and reassembled substituting araldite (epoxy) for assembly paste. If that doesn't stop it slipping, nothing will
FWIW, I think the problem is likely to be at least partly due to the inside of the steerer not being even, therefore offering less grip to the expander plug. The FSA you link to probably couldn't be any worse than the Deda, but might not be any better...
