SEAT POST:
SDG I-Beam
Our new I-Beam seat post replaces our carbon fiber seat post
and is lighter by 70 grams. The I-Beam seat post is made out
of 2014 aluminum in a SuperOversize 34mm diameter. Laser etched
measurements on the seat post let you get immediately to your
preferred riding position. Combined with the SDG I-Flex saddle,
the total system weight of the SDG post and saddle is a whopping
100 grams lighter than last year's carbon post and Ti rail
saddle. A Dahon exclusive.
