The Pittsburgh Alu 1.5 from the German manufacturer is equipped with 24-speed Shimano XT/Alivio STI and Magura HS33 brakes, and that all-important fat-and-stiff headtube. The One-Point-Five Interface Standard was developed at Interbike 2001 by Race Face, King Cycle Group, Rocky Mountain, Cane Creek Components and Answer/Manitou. Cannondale later adopted the standard, too.

The One-Point-Five Interface Standard was developed to create a common set of head-tube, head set and fork steerer interface dimensions to promote standardization and allow the exchange of fully compatible parts between various manufacturers of branded components.

The current 1 1/8 standard used for MTBs was established when bikes did not have front suspension. Increasing diameter makes for an increase in both stiffness and strength in all steering and head tube components, with minimal weight gains.

With the One-Point-Five Standard, Manitou claim a 44 percent increase in fork strength and increased stiffness of 134 percent.
