I have a 26 Giant anthem x3 and need some advice on stem sizes. I have always been a big fan of Renthal and been using there gear on motor x bikes for years. I bought the Renthal fat bar lites for my mountain bike, and I was interested in the Renthal duo stem. Renthal only do a 50mm version on there stems which I thought would be ok but after reading about people saying the 50mm stems is not ideal for a cross country bike and especially the anthem. I currently have the standard giant connect 110mm stem which is a bit to long for me and I prefer the shorter stem as I am a fast trail type of rider. My bike has overdrive which to be honest I don't really know much about it just thought I would mention it incase that effects choosing a stem.
If it helps I am around 5ft9 to 5ft 10 and the stem must fit with the renthal fat bar lites. I also like a stem with a bit pimpy style to it lol :). Here is a link to my anthem (mine is the medium 18 inch). If you click on geometry It will give you the exact geometry of my bike. Thanks!
