Does anyone own one of these frames or similar, and can shed any light on the seat post clamp situation. My frame came with a wedge, similar to a quill stem wedge, and a bolt. JE James list the same item but it just doesn't look right to me, looks like there should be another wedge for it to work. I haven't got a seatpost so can't really give it a try. Just wondering if any other Look owners might know the answer.
