Hi Guys,

I need a replacemnet Seatpost for my Foil, however, the dealer is telling me he can only get a 20mm (currently I have 5mm). Having never ridden a 20mm Seatpost, is there much difference? If I run my seat 15mm forward, that surely negates it? Or is the angle slightly different as well?

Thanks a lot!

Some people have a preference for where the clamp holds the rails because the way the rails flex and where the fulcrum is, and some people need it because they've maxed out adjustment on their rails.

But yes, if you have the adjustment room then it will work.
