I need some opinions. I'm currently riding a 16.5" 2002 Azonic DS-1 frame, and I want to upgrade to a Planet X Jack Flash. My question is: should I get the Jack Flash with a 21" or 22" top tube? (My Azonic has a 21.6" top tube.) I use the bike for pretty much everything, which includes downhill, street, trail riding, and dirt jumping, and I plan on using a 10 degree, 70mm stem with a 5-inch travel fork and 1.5" riser bars. Ultimately, I want the new frame to feel as similiar to my Azonic as possible. Thanks.
