I'm looking to get new headset for my prophet with tapered fork,
I know I need top cup ZS49/28.6 and bottom cup EC49/40.

My question is this, in the "post your prophet" section I noticed some of the bikes using normal fork NOT lefty seem to have deep bottom cup so as to stop fork crown hitting the frame,
Does anyone know which bottom cup I will need...???

brand/model/size depth..???

I used a standard 1.5" to 1.125" conversion crank brothers headset (straight 1 1/8" steerer). Any external bearing with an OD of 1.5" will work but yes needs to be external so fork clears frame. ID depends if you have a tappered steerer or not. EC49 will work.
