Hi Hokiefyd,
The new rotors are SRAM “ Rotor Cntrln 160mm, rounded“. They work much better on the Hy-Rd disc brakes, than the lighter ones that had larger gaps that were rubbing & stuttering.
I am thinking about a 35-45 degree stem to get the bar up closer to the height on my MTN bike, although I may ride it as is for a while.
The handlebar is carbon and does seem to help with vibrations on the gravel roads here. I have some permanent nerve damage that causes my hands to go numb.
