I believe this is a 1994. This is the Klein Pulse, a frame that has a 1-1/8 head tube and geometry compatible with a suspension fork. The frame measures about 19-3/4" center to top. I believe it is a 19", and the seat tube is extended by the zip grip collar. I believe it is 19" because the top tube that is approximately 22-3/4" long, which matches the 19" in the catalog. This particular one has the Zip Grip seatpost clamp, which twists a collet to tighten the seatpost into place. It is working. The Thomson seatpost is not included. It was just in the frame to test the Zip Grip, and I forgot to remove it before taking pictures. There are no cracks or dents. The bottom bracket spindle is smooth.
