Hi, I've got the 29" version and went for a 29" Rockshox Recon RL Solo Air Fork. Entry level to Air Fork but soo much better. I am sure they do a 27.5"
Tried Cross tires which were almost slicks as I do mainly road and pathways for my commute. Went back to stock tyres, they are pretty good. I got my shocks from Merlin Cycles in UK. Wait was a little longer but were a good price.
