Thorn General / Re: Thorn stem problems
« Last post by Andyb1 on Today at 02:00:44 pm »You are right Phil, my 130mm stem has a 17 degree angle, not 14 degrees.
It also has M6 clamping bolts, not M5, so I went up to 10NM - but there is still a slight rock and creak.
I think a stem with a 4 x bolt clamp is the way to go, even if it has to be black - polished alloy stems in 25mm seem rare.
My handlebars just rock a fraction in the clamp, I would be very worried if they could rotate as there could be scratches cut into the handlebar that would later crack.
Did your handlebar fail around the edge of the clamp Phil?
