SDG I-Beam Carbon Micro Seatpost 30.9 x 400mm MFPN=00.5018.037.011 with its flexed-tuned FACT carbon

with its flexed-tuned FACT carbon shell and ultra-light rails

This revolutionary process creates a complex honeycomb structure that allows us to infinitely tune the material’s density in a way impossible with foam

Clamp fits any diameter between 22-38mm (shims included)

CrMo rails and durable construction
