Well im new to the downhill/freeride scene, i rode a friends bike and i was instantly hooked, so i want to convert my 2007 GT chucker 2.0 into a meaner bike so i have been looking at forks, i am probably picking up a pair of 2005' NIXON super IT with 145 mm of tavel and along with those forks im buying 20mm marzocchi front hub and then a front and rear Magura Venti Disc brake rotor, ROTOR ONLY, and i have a stock sized 6" brake, so i need to know about the deal with brake adaptors theres the 74mm gap between bolts or the 51mm i believe this fork im buying is a 74mm, but im not sure how the spacers work where you can convert the gap from a 74mm to a 51mm, and if so i need the 74mm to the 51 right? well so far this site hasn't let me down so thanks guys!

The adapter depends on what type of brake you currently have. So... what brake do you currently have? What size rotors are you looking at?

It's not a good idea to put all this stuff on a frame that was never intended for DH/FR. A longer travel fork will slack out the frame, jack up the BB height, and put more stress on the headtube. The geometry of a freeride bike is much different than that of a DH bike, and both are entirely different machines than cross country or recreational bikes. Isn't the Chucker more of a dirt jump bike?

lol dont get much into the forks, how is 145 a much longer travel than 100mm? well i'll ask around about that much later even if i have to go to one of my LBS, i have a 6" brake rotor, and my current setup for brakes is 51mm, so if i put a fork thats a 74mm gap i need the downsizing piece right?, yeah the way it sounds i might just be buying a pair of DJ two's...thanks
