THM Mandibula Lightweight Carbon Seatpost | 27.2mm

Two zone comfort design | 159g (350mm) | Stiff regardless of insertion depth | 110kg / 243lb weight limit | Road, gravel, CX, XC and MTB Mandibula splits the seatpost into two zones to solve the problem every comfort post runs into: the farther they stick out of the frame, the more they flex, which unfairly punishes taller riders. The power zone stays super stiff and light no matter how much of it is exposed, while the comfort zone provides just the right amount of give. THM's layup keeps the saddle horizontal through that flex path, unlike conventional flex posts. Features Two-zone design: a stiff, low-flex power zone plus a dedicated comfort zone Stiffness in the power zone doesn't degrade with more post exposed, so taller riders aren't penalised. THM layup keeps the saddle horizontal through the flex path, unlike conventional flex seatposts Compact design fits small frames and frames with a horizontal top tube Proprietary carbon layup dampens oscillation at higher cadence and on rough roads or cobbles, reducing rider fatigue Lighter than most seatposts that don't even have comfort features Specifications Material Carbon/Basalt Weight ±5% 159g (350mm) - 172g (400mm) Seatpost Clamp Diameter 27.2mm Setback 25mm Saddle Clamp Diameter Ø 7 mm or 7x9 mm oval (carbon half-shells for both included) Finish Natural Carbon/Basalt Minimum Insert 100mm Max Permissible Total Weight (rider+bicycle+luggage) 110kg/243lb Compatibility Frames with a 27.2mm seat tube Road, gravel, cyclocross, cross country and MTB bikes Saddles with round (7mm) or oval (7x9mm) rails Links View the THM Collection Download the Instruction Manual (EN)
