Bamboo seat tubes bored on one end to accept our 27.2 mm seatpost sleeve. Allows 130 mm seatpost insertion (5″). Tubes have been treated with epoxy and expanding foam on the lower end to prevent water absorption. These tubes are not wrapped and machined for front derailleur clamps. While a clamp may fit, they will often slip down if the clamping area is not stiffened up with an external wrap and then machined/sanded round.
Weights and dimensions are shipping weights and box dimensions. Tubes are 66 cm or longer.
One week lead time to process the bamboo.
