Specialized OSBB PressFit for Dub (29mm) MTB Crank Sets

  Info Installation Instructions Video Specifications JUST THE FACTS: Our DUB OSBB PressFit MTB module works with all DUB mountain bike crank sets on the market. All of our modules ship with the special press tools and retaining compounds you'll need. All you need is the press. NOTE: OSBB PressFit MTB is NOT the same as OSBB MTB or PF30 MTB. OSBB Pressift MTB is 46mm x 73mm. OSBB MTB is just BB30 (42mm x 73mm) by another name. Although OSBB Pressfit MTB and PF30 MTB look the same on paper, 46mm x 73mm, there is a slight diameter difference due to the way Specialized manufactures their carbon frames. For the perfect match to your carbon Specialized frame use this product.
