@jd_3d Thanks for the info. I thought you chose 1:1.5 arbitrarily, rather than due to mechanical constraints.
Anyway, I have to say that the LSS is an amazing add-on and a must-buy for anyone with a Levo. It really does make a huge difference.
@jd_3d I'm using the LSS DT 2.0 on a Levo Expert. It works flawlessly and makes a huge difference for me. However, I do find it strange that you didn't choose a less restrictive ratio; I'm in the UK and still limited to 22mph. Are you aware that someone's planning on releasing a similar device...
