You can choose whatever stem you'd like on this bike. It handles well no matter how long. I bought a 80mm stem from PlanetX for this bike, but postal service didn't deliver it and ended up sending it back, so now I am waiting for PlanetX to resend it. As the guy we built it for is only 13 years old he will need a shorter stem, but as he grows he will be able to get larger stems ;-)
