27.2 Seat Sleeve


Bamboo Bicycle Club Team

“Our 27.2mm sleeve is perfect for bamboo frame building. Narrow enough to fit inside bamboo which will be compatible with a front derailleur. You can also use a dropper post or any standard 27.2mm seat posts. Knurled for longevity as without can easily debond”
