Looking for a Dirt Jumping Fork
 

As the title says I need a dirt jumper fork.
Needs to be 1 1/8th STRAIGHT steerer not tapered and 100mm travel.
I'm putting it on my 2014 Norco Rampage frame, and I dont mind spending up to $300 but $400 would be my max. So with these specifications, what forks should I be looking for? Rockshox, Marzocchi, Manitou? I've been looking at the Mantiou Circus which seems to be in my price range, but how heavy is this fork? Is it not worth the money If im looking to get some weight savings?
Also looking to buy the Spank Spike Race28 wheelset. Is this a decent wheelset for dj?
Thanks.

I have some friends that say Manitou is a great brand for forks, very underrated. They make the fork in a 26 wheel size which would be a lot better for DJ. If you go with a Pike 120 mm, then you need to go with 27.5. I won't look at Fox because you will need to go used in order for that to fix into your price range. As far as those wheels go, I like spank products. I currently run a set of their rims and they are solid. Some of the stuff I have put them through has been pretty rough and no complaints.

Cirrus Expert is probably the best bet for a straight steerer https://www.manitoumtb.com/products/forks/circus-2/ . It has an air preload adjustment on a coil spring and a real and reasonably designed damping stack tuned for DJ. You can also try to pick up an older air sprung fork, preferably larger stanchions, and possibly travel reduce it and possibly even adjust the compression stack, but that's getting pretty deep into suspension tuning and work.
