It's a 19"
The feeling with a flexstem, is near the ride of a full rigid bike. You don't really feel the rear suspension (yes, there's a lateral flex, and the feeling of a flat tire)
Only rear suspension wasn't a so bad idea : you have more weight on the rear than on the front of the bike, and when the suspension works, the bike is really more stable.
I love this bike with rigid fork.
But you can ride it with suspension fork. The ride is not so bad.
But the bike becomes heavy, I you have to find an RS1, mag21 or a manitou (very low suspension fork) for keeping the original geometry.
Your bike is a SE1000, all suntour equiped.
You have to remove all these ugly modern parts
