With the tarANTula we have raised the bar significantly in terms of versatility. Shine on the downhills while running 650B+ 3.0 wheels or put in your 29+ wheelset for off-road adventure trips. 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 gearbox of your choice (18 or 12 speed), the tarANTula takes all these wheel- and tire sizes. The listed specification is our suggestion and runs on 650B+ 3.0 wheels.
