I got rid of it completely.
Keep doing the eccentric calf raises. Also, stretch your calves after every run and every ride. If the calf muscles are tight, then the achilles is tight. So don’t wait for a “slight twitch” to remind you to stretch. Make the calf stretching a habit. I also roll mine w/a foam roller (rumble roller) or a stick (the stick).
Note, mine was never triggered w/cycling. I only felt it if I tried to run. I could cycle w/out issue. In your case, definitely make sure your bike fit is appropriate.
