Bike too small some help? Just bought an used xs specialized sirrus sport in great condition. I am 5'8 and just realized that is too small. Just wondering if there anything that I could to do to make it fit me? Got it today so I haven't try anything yet
You can follow the advice of Chris H : Change bicycle.

But, if you have access to cheap-already-used-spare-parts you could try to change the seat tube and the stem. 
Though, it will probably never be as comfortable as the good frame size.
