7075 vs. 2014-T6 for stem material
Hey all, looking for some advice on stems here. I am looking at two models by FSA, the OS-115 and the OS-140. The 115 is made of 7075, forged and then machined and weighs around 120gm (with titanium hardware). The 140 is made of 2014-T6 al, forged and machined, and weighs about 150gm (with steel hardware). Is there any significant difference in strength or stiffness between these two stems/materials, other than weight and price ($110US vs $75US)? Will one stand up to abuse better, last longer with the same use?
I am a heavy rider (230lbs) but have never had any stem/bar problems and don't ever find myself getting too agressive with the bars. I am hoping to get some answers from those of you who maybe have tried one or the other stem, but also those who know a bit about the metals and their durability/strengths/weaknesses, etc.
Please feel free to chip in if you feel I am overlooking another great product in my search for a stem as well (I prefer the 84 degree angle though).
Thanks in advance guys!!
