Helo Pipi,

I think you are very brave to attempt a full suspension first build, given its complexity, not to mention added weight.

Have you thought about having balloon tyres instead, such as Big Apples/Big Bens. These, together with a mesh style seat, give a very plush ride, as I and many others will attest to.

Anyways - it's your build, and you must follow your hearts desires. Good luck and keep us posted.
