The Superbe Pro post is an adjustable Road Racing seatpost, using two fastening bolts to grip and cinch the clamp. The upper clamp piece is made of Silver anodized, cast aluminum, with a square and a round recess cast into the top for a steel nut to seat. The upper clamp piece provides 1 1/4" of surface contact to the saddle rail. The lower clamp piece is made of Silver anodized, cast aluminum, with a single hole through it for one of the fastening bolts. The lower clamp piece also has 1 1/4" of contact to the saddle rail bottom. Between the two clamp pieces Suntour has fit a volute spring, (one of the springs used on quick release skewers), to keep the clamp open when the bolts are loosened, making saddle installation more convenient.
The head piece is made of cast aluminum, hollowed on the bottom to reduce weight, with the fastening bolts passing up from the bottom through the clamp pieces into the nuts over the upper clamp piece. The front fastening bolt (5mm allen head), holds the saddle and clamp on the post, while the rear fastening bolt, (5mm allen head), is used to make small saddle angle adjustments to dial in your perfect comfort.
The head piece is pressed into an aluminum alloy tube that has been turned on a lathe to the proper final dimension. The head piece is not only pressed to a one inch depth into the tubing section, but Suntour also has a 5mm aluminum rod running through the rear of the post. The head piece and is buried in the front of the tube section, (unseen from the exterior), to positively make sure the head and post don't separate. With the clamp perpendicular to the tubing section, the center of rail to end of tube length is 251mm. The weight of a 27.2mm Superbe Pro post is 281 grams. The Suntour Superbe Pro post is made in Japan, and is available in 26.8mm, 27.0mm, and 27.2mm sizes.
