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 have been wrapped and/or machined for 35mm front derailleur clamps positioned about 6″ from where the center of a bottom bracket would be positioned. Specify length.
Weights and dimensions are shipping weights and box dimensions.
One week lead time to process the bamboo.
