That’s a good question. The 650b/700c version was definitely not boost. I don’t remember anything in the various threads on them that settled it for sure. The last thing I recall was a couple of months ago, don’t know if anything has changed.
Our Bootzipper project is nearly ready to launch.
Final tweaks on graphics.
They will come in 650B and 29in versions.
650B model takes our gravel wheelsets and so is 12×142 rear, 100×12 front, rigid only, 405mm fork length, non boost drivetrain.
29er is 148×12 rear, 110x15mm front, 440mm fork, boost drivetrain.
Both have post mount frames and forks and 44mm head tubes
Should be available in a couple of weeks though.
