For Cyclocross Thomson presents the Katie Compton Signature ‘cross bar. Katie brings her multiple Championships, European racing and Olympic experience to give you a bar built her way for cross. The natural transition from your Thomson road bar for the ‘cross season. Twin flats on the bottom of the bar allow taping your housing to create a round bar when wrapped. Top profile is round and as wide as possible. This is the carbon fiber Cyclocross handlebar built to take all the season can dish out. This allows auxiliary brake levers to be safely used and still leaves lots of room for your hands. Certified to EN, tested to DIN+.Layup uses 3 different fiber types with different tensile strengths and tensile modulus, including High Strength carbon fiber. This helps allocate stiffness and flex where needed.All carbon fiber is produced by Toray and uses tailor made Nano Epoxy Resin for very high impact resistance. Toray is the main supplier of carbon fiber for Boeing and Airbus.Both the Road and Cross bar are made in one piece, not three pieces co-molded and glued together.Bars are molded over an EPS mandrel to avoid wrinkles inside the layup during molding. Most other bars are molded over inflatable nylon bladders.Reach for the Roadbike and Cross bars is the same at 78.5mm. Drop is proportional.
