KCNC SC13 Twin Seat Clamp
KCNC's Twin Clamp is designed to solve the annoying slipping seat post! It does happen - and this clamp is designed to prevent posts slipping down inside the frame by having 2 clamps joined together - one clamps the seat tube as normal but the top clamp grips the seat post itself to provide an extra clamping force without over stressing the seat tube clamp or the seat tube and seat post itself!
Comes in 4 combinations of seat tube/seat post size - 30.7-27.2mm, 31.8-27.2mm, 34.9-30.9mm, 34.9-31.6mm.
CNC machined with two Ti bolts make it light enough!
