Ill comment.
As for bar and stem I had what you have now and it weighs a tonne, I changed to ody milk bars and elementary stem super light saved about a 1/1/2.
I also changed my forks to ody pro dirt again saved a 1lb
Tyres and semi worn tyre by maxxis are good, I love my hookworm not to heavy but great puncture protection, pumps upto 110psi same with the ringworm, miricale or m-tread.
