I'm 5'10" with a 32" inside leg and it does definitely seem to work for me. It obviously depends on how long your torso is, but you can go on my measurements to get an idea. Thanks for your comment 👍

@@IrelandRider I`m 5.5 with 29in leg but i think im going to try one do you get the wind push your head towards the front of the bike ,i think thats why my neck is killing me i rode from south warwickshire to Stonehenge yesterday around 160+ miles but love it, also what camera are you using ? I`ve got Drift Ghost xl

@@Tricky66 I only got the wind at the top of my lid before I put the extender on, now with it on, it goes over my head, so I was thinking if I was your height 5'5" the factory fitted screen should suffice, but the extension screen would definitely eliminate all buffering 👍
