The Haro Carbon Pro race frame comes with PTC bottom bracket housing. By using tapered components that all taper to the outer width of the housing - Haro have achieved one of the stiffest and strongest BB-setups available. (BB sold seperately)
The rear droput is supplied in three different sizes - 10mm, 15mm and 20mm. This makes it suitable for a wide range of axle setups.
The headtube is tapered from 1 1/8" - 1 1/2" which makes it stiff and also allows for a setup with the CliQ Citizen fork.
A blend of M30-S and T-700 carbon makes this an extremely light and robust frame.
