Couldn’t do without kickstand on trek 520 (add on). However biggest issue when using or even standing at a light or stopped for a photo op is front wheel flop.

regarding kickstand. Must be sturdy enough to hold 30+ pound bike with 60 pounds of gear. Make sure bolts are tight from time to time.

last year mine began to unscrew without me knowing and subsequently bent the bolts which the snapped as I tried to unscrew.
now it’s part of regular checks to see that bolts are nit coming out.

the convenience far outweighs the weight.
