well there's an assortment of kinds. There's air bags, struts and cylinders.
Bags mainly allow you to do f/b/s/s and three-wheel but you will need to hit a tight turn for it
struts do the same, haven't herd anyone do a 3 with em yet
cylinders same, 3, and dog leg if you add the extra valves to it.
EAI is commin up, Firestones not sure about them anymore, Slam Bagz are pretty good.
1/4" is the slowest, 3/8" is decent, 1/2" very fast, 3/4" oh yeah :biggrin: and the 1" IMO, is the best for hopping.
ViAir, Blow Jax, Jun -Air are the top leaders so far in compressors
Tanks, go big!! I can't stress that enough. 5, 6, 9, 12 all good, 8 ported if possible
Nitrogen is a must for hopping
