Great stem

Bought this for my Giant (there's not much choice for OD2 stems) the design wise the stem looks great and the option for Di2 routing is a nice touch (potential to place battery in the steerer). Comes in at around 140g for the 90mm which is good for an alloy stem
Reversing the bolts is meant to make it more aero, which it might but it does make it awkward to torque them correctly; you'll need a long hex key to avoid scratching the stem (hence 4 stars).
Shaped topical, bolt and carbon assembly paste are included which is a nice touch, if you want to put spacers above the stem them you'll need a special upper spacer, the same applies if you want to use a standard round top cap too.
Function wise the stem is great and looks great but the design has it's nuances, as said there's not much choice when it comes to 1-1/4" stems but I'm glad I choose this one.
