[b]What are the hazards?[/b]
Injury
[b]What are the defects?[/b]
Dute to fatigue these stems may crack and eventually break. If this happens during cycling, the cyclist could lose control of the bicycle, which may lead to serious injuries.
=====
So, carbon stems - prone to failure over time?
From the pics, that seems to be a carbon tube bonded onto ally clamps. I suspect the issue is with the bond?
Easton are doing a EA30 stem recall too.
=====
So, alloy stems - prone to failure over time?
no more or less than aluminium ones, see the stems that Easton recalled a week or so previously
The torsional forces going through a bonded sleevey type construction like those must be taking some stress.I wouldnt trust them.I would trust carbon made in diffrent ways though,like the Time monolink.
This recall was mentioned in the u.k through email but why dont the brands forward it onto all the big websites? or have they? i havent looked elsewhere so maybe i missed it.
