With the tarANTula we have raised the bar significantly in terms of versatility. Shine on the downhills while running 650B+ 3.0 wheels or go on an off-road adventure trip. If you get the feeling that big tires are holding you back when racing your buddies on their carbon 29-ers? Just slap a set of 2.4″ tires on it and (try to) show them who is boss. Designed around a Pinion P1.12 gearbox, the tarANTula takes all these wheel- and tire sizes. The listed specification is our suggestion and runs on 650B+ 3.0 wheels.
