BB386 EVO is a road bike bottom bracket standard introduced back in 2011. The BB standard is based on a frame shell width of 86.5mm and inner diameter is 46mm. The inspiration behind the design was to oversize. While similar to conventional threaded, BB90/95, and PF86/92 bottom brackets, BB386 EVO incorporates a larger 30mm diameter spindle. Why do you care? Well, that oversized spindle and shell increases stiffness right where it’s needed most. Ever watched a BB shell twist side-to-side when hammering on a trainer? Yikes! A mountain bike version 392EVO exists, but sightings are more rare than the Loch Ness Monster. Bottom brackets are the same between both mountain bike and road versions. Features • Road and off-road specific seal options to keep your road, triathlon, TT, cross and mountain bikes running smoothly • Designed to fit any crank and frame without adapters or fuss factor • 2-Year, very few questions asked, confidence inspiring warranty
