Lynskey Helix Titanium Road FrameThe new Helix features the David Lynskey designed 6/4 triangular shaped top tube. Benefits include an increase in overall frame stiffness and handling, while enhancing the look from stunning to traffic stopping This bike is a titanium marvel that harmonizes strength, stiffness, speed and weight with a welcome face lift that may cause your current road race bike to have paranoia and anxiety from attachment disorder. In other words, you'll not be riding it any more.A happy Lynskey customer had this to say.. "I have a 2012 Obea Orca Gold (very fast, very stiff) and a 2007 Litespeed Teramo (very comfortable but heavy and sluggish in the mountains). Was looking for something fast like the Orca but more comfortable like the Teramo. I have to say I think I have found the perfect bike The new Helix rides fantastic. You still have the smooth Ti feel but the responsiveness in the mountains is there. Out of the saddle speed and quickness is instant, no give in the BB area Have not taken it on a century yet but expect it will be my go to bike for long days in the saddle The Litespeed has been given to my son and the Orca is hanging on the wall. I have not forgotten her but I seem to keep grabbing the Helix on my morning rides "Features: Tubing: Race-tuned Helix Technology tubeset for maximum stiffness and power transfer Headtube Design: Tapered 42/52 headtube for Integrated HS Bottom Bracket Type: 68mm PressFit 30 Seatpost Diameter: 27 2mm Seat Tube Diameter: (Front Derailleur Clamp Size) 34 9mm Wheel Size: 700c Max Tire Width: 28c Dropouts: Interchangeable Hanger for QR or Thru Rear Spacing: 130mm Brake Type: CaliperBuy Lynskey Frame Spares from Chain Reaction Cycles, the World's Largest Online Bike Store.
