Not to knock either of the air canisters from Fett Bros or Nextech, but neither of them is that great of solution compared to others out there.
I'll explain - the units from both of these are JUST adding volume, which is the samething a FLOAT 2 does over a the old float. this is not bad, but it still not enough considering the price they are asking.
The better method is the canisters that have an internal piston. I got them from Holz last year, but i don' think they are selling them anymore. Too bad. I'm pretty certian though that Tom's is going to be offering an Evol End Cap kit from Fox that is the RIGHT way to add volume and features to a base float shock.
Real quick i'll explain what's the difference between the two types of add-on canisters. Just adding volume via the Fett bros or Nextech kit IS an improvement over stock. HOWEVER, selling your base floats and buying Float 2s would be a MUCH bigger improvement and about the same money. Float 2s offer more air space (like adding this chamber) PLUS they much improved features that get rid of the harshness and chop feel of the stock cat shocks. don't be fooled - the float that cat offers and the ones you buy aftermarket are pretty big. the stock float has some pretty crappy parts in it and no negative spring (the reason for the harshness).
Now - adding the "chamber" to the stock float is still a good move, however - try and get your hands on the piston version. the difference is that piston version has two air inlets on it and turns your float into a "dual rate" spring. This is the REAL benefit of the canister (as well as adding more volume, which helps with plushness). with the piston version (just like Evol R and Evol X have) you dial in your sag seperate from your bottoming resistance. I paid $100 per chamber last year from Holz, but like i said he doesn't sell them anymore i don't think. Too bad.
I think Tom said he's have these for sale around 12/1. Definitely the way to go and i believe they will be geniune FOX part. Cool.
