We worked closely with Hobie Doan on his signature Roll Up frame to give him all the specs and features he was looking for in a super tough frame. The investment cast chainstay yoke creates a clean look, while providing extra stiffness and a ton of tire clearance. For the seatstay bridge the frame features an oversized laser cut bridge for more stiffness and a great look. Modern street geometry throughout the frame of course, with a 75-degree headtube angle and 12.75” chainstay length. The dropouts feature an all-new shape based on Hobie’s input and feature integrated chain tensioners to ensure your wheel stays in place and chain stays tight. This frame includes removable brake mount hardware and an integrated seat post clamp with a handy 5mm/6mm combo bolt.Seatstay BridgeOversized laser cut bridge for more stiffness and a great look.Dropout and TensionersLaser cut 6mm thick dropouts with integrated chain tensioners.Investment Cast Chainstay YokeThe investment cast chainstay yoke creates a clean look, while providing extra stiffness and a ton of tire clearance.Geometry:Toptube Sizes 20.5” / 20.75” / 21” / 21.25”Chainstay Length 12.75” SlammedBottom Bracket Height 11.75″Standover Height 9.25″Headtube Angle 75°Seattube Angle 71°Headtube Height 5″Tech Spec:Material 100% 4130 Chromoly TubingHeadtube Integrated Campy SpecDropouts Laser Cut with Integrated Chain TensionersBottom Bracket Internally and Externally Machined Mid Size BBBraking Removable Through-Bolt Brake Mount SystemParticulars Toptube and Downtube GussetsIntegrated Chain TensionersIntegrated Seat Clamp with 5mm/6mm Combo BoltInvestment Cast Chainstay YokeOversized Super Stiff Seatstay BridgeWeight 5lbs (20.5″)Dimensions 95 × 33 × 16 cmTopTube 21"Color black
