You are aware the DJ2 is a dirt jump fork, correct? Not sure if it will work the way you want it to on the trail as it's meant for dirt jumping.

According to GF's site, your bike came with a 100mm fork. Going to a 130mm fork will slacken the headangle some and change the handling characteristics of your bike. From what I've read, it's generally recommended to not add more than 20mm to the stock set-up of most bikes. How does the axle to crown measurement compare between your 100mm fork and the DJ2?

I doubt going from 100mm to 130mm will effect too much. I'd be more concerned about how well a dj fork works for trail riding.

I measured the hub center to crown after i mounted the 130 mm. DJ and it was 19 in. the 100 mm. was about 18 3/8 in. about 5/8 differnence that is not to bad and it did not slack the head angle as much as i thought it would.
