Hi,

I'm planning to make my perp more fun to ride. I want a 160mm fork in the front and a air shock in the rear.
Chris Van Dine from The Cut rides with a perp with 160mm front travel. I think they did a little correction of a few mm's on the rear shock to prevent f*cking up the geometry.

Does anyone knows how it's possible to mount a FOX 36 without any negative geometry thingies?

Thanks in advance!

well i'll use this thread to ask if anyone rides perp with dc fork (boxxer). How stable is at high speeds and how well does is corner?

cheers

No one has any advice?

Should I do it or not?

If you want to keep the original geometry with a 160 mm fork, you'll need a shorter eye to eye shock. To figure out how short, you'll need to pass a geometry class and remember what the heck the teacher was talking about (so I can't help you there).

My friend is running an 8 inch Boxer on his. He loves it and says the bike is incredibly maneuverable. Rides like a trail bike but w/ a dual crown fork. He'll be racing it @ the Open this weekend. That'll be his first day on lifts with it....

Hey.

I ride a 2008 Perp with a FOX float 36 Rc2. I use this setup for light DH racing and all around having fun. The bike is very light/maneuverable and feels good on all but the roughest sections. I run it in the 7" setting most of the time. I do feel as if the bike rides better in the 8" setting however. I use a bit more spacers under the stem to bring the bars up.

So there won't be anything like a bad geometry?

What is the weight of the perp like the picture?

If you want 160mm and light (30lbs) ....

 

[Gieleuh]

Yeah, I wish I had the money for a bike like that. But no carbon in MTB for me!

You will definitely need a shorter eye and I have no idea how short it will need to be, sorry.
