I have a 2014 Look 695 Aerolight with a ISP...the problem I have is that the post topper (E-Post Ti) has a 30mm offset. I generally have a 0 offset on my 54mm/55mm bikes as I'm short, 5'9" with a short inseam. I've managed for years by having the topper adjustment pushed as far forward as possible, but unfortunately, the fore and aft mechanism is then unstable and will slip backwards.
I see no solution to this issue with the current topper and does Look makes a couple of additional toppers, the R5 and the R32 which have a 0 degree offset or are reversible, but needless to say, they impossible to find.
I've read some comments over the years about converting the ISP to a standard seat post or possibly utilizing another brand topper, so I was wondering if those with longer experience might have some guidance.
