APRO's removable mandrel produces a smooth and uniform surface within the carbon frame, allowing for less material for the same strength. The resulting bicycle frame provides superior strength and stiffness while being extremely lightweight. (Patent : M412121)

Rear Drop Pivot is a Horst link style suspension system. The four bar link design allows for fine tuning on both wheel travel path and shock rate.

Tapered 1.5" lower to 1-1/8" upper; 1-1/4" to 1-1/8" is also available. Tapered head tube designs are stiffer and stronger than conventional straight head tubes, with the added benefit of offering a greater surface area for welding. Minimal flex at the front of the frame provides increased steering precision and accuracy.

Direct mount front derailleurs provide for increase front derailleur stiffness and perfect alignment Direct mount derailleurs eliminate the clamping system, toeliminate weight, and work with press fit bottom brackets.

Direct mounting your rear brake provides additional torsional stiffness and eliminates adaptors, bolts and excess weight.

Along with BB86, this Shimano BB92 Bottom Bracket is part of the new press fit standard. Typical mountain bike has a 68 or 73mm bottom bracket shell width, a BB92 equipped bike has a shell that measures 91.5mm wide and has a 41mm inside diameter.
