i am 32 years old and am 6'3" tall. I want to buy a new bike and am thinking on the 2008 gt power series xl. is this a big enough and good enough bike for me?

Noob,
I am 6-1 and am really comfy on a Redline Flight. The Gt also comes with alloy cranks you need cro-mo. I say Redline Flight all the way until you get fast then switch to whatever you like and have researched or are sponsored by.......Allen Godfrey

Look first for a frame that fits you, after that the other parts are easier to replace.

deja vu

crazy weird

Deja vu all over again.

I say "aye" to the Redline as well.

Another vote for Redline from me as well. Question though, are you going to be riding 20" or Cruiser class? Make sure you know what you want to ride before buying the wrong bike.

The Redline in either cruiser or 20........though I am about to retire mine for a next gen bike......Allen Godfrey
