I have a 2011 knolly delirium I just picked up from a buddy and I love everything about it, it has a bomber 66 rc2 on the front and i want to swap to an air fork. Any recommendations? I'm new to the sizing aspect and not sure what would be the most ideal/compatible for AM/enduro with lots of drops and jumps. Also compatible with 26 inch wheels. Or can I swap up to a 27.5 fork? Sorry if I'm dumb hahaha
