My friends only 5'2" tall and she rides a 2010 Reign SX as her only bike. We've already got the only spacers the head tube/stem combination made room for on top of the stem. Would like to get a little lower. I have seen on someone else's Reign with a flat headset top bearing seal/cap. I tried to make sense of what I'm looking for on the FSA website with no luck. Anyone point me in the right direction? Her bars are already pretty flat and I think playing with spacers gives us a little more flexibility.
