BERK Lupina Monocoque Open

A 249 mm one-piece (monocoque) saddle with a flatter, less pronounced central area that still delivers the flex of BERK's longer saddles.

BERK Lupina Monocoque Open — Features & Benefits

Lupina Profile: a refined sitting area with even support and generous flex.
Even Pressure: BERK's “flat-flat” profile adapts to your hips, spreads load evenly across the sit bones, and eliminates point loads.
Saddle Flex: a one-piece (monocoque) carbon shell gives natural flex that follows your body for comfort that improves over distance.
Rider Fit: tuned for road riders and stable across aggressive and relaxed positions.
Discipline: best suited to Road.
Two Finishes: choose padded (125 g) or 3K carbon look (105 g) to match your build.
Carbon Rails: oval 7 × 9 mm — confirm your seatpost clamp supports oval carbon rails.
