27.5"+ 29"

Handmade in Canada, The Primer is designed around 29er or 27.5+ tires with clearance for up to 27.5 x 3.0*.

The Primer compares closely to our new Rootdown B.A. using what we would describe as our most progressive 29er geometry to date. The shortest stays possible. Lower than ever BB height. A steep seattube with a slack head angle, low stack headtube and long front center. This combination is the best descending 29er we’ve ridden yet it still climbs as well as our previous versions.

27.5+ is new and with only a few tires on the market it remains highly undiscovered. The cool thing is that it compares in diameter to a standard 29er tire. By adding tire clearance we can make a bike that works with both wheel sizes leaving the options and possibilities wide open.
