Using this on my Trek Fuel EX 8. Picked this up to cut a little weight from the bike and I wanted a slightly shorter stem. Has worked great for the entire season, it is just the right length and weight.

Shipped fast and packaged well.

This steam is really what I was looking. Really light(only 98 grams) but very resistant and stiff. I combined it with a FSA Carbon handlebar and I love them.

I've been using the OS-99 stem for a while now and have this in a few different lengths.
Very good value for money.

This item is very light and great quality. Why buy carbon where aluminum is just as light. Very happy!
