The new TR12 rear derailleur is able to provide a quiet and accurate ride over the roughest trails. The key feature to this pursuit is the Hall Lock. During the Race season, lead mechanic for Intense Factory Racing, John Hall, noticed excessive movement around the B-knuckle when riding over rough rock gardens and in tracked out corners. This was leading to more chain skipping and slapping creating possible variances in shifting. This inspired John's idea to lock the B-knuckle to the bike's derailleur hanger. TRP engineers worked closely with Hall to create this feature, The Hall Lock.

The new Super Record 12x2 Speed mechanical front derailleur: lightness, design, fluidity, and effectiveness.
The new Super Record 12x2 Speed mechanical front derailleur introduces many new techniques, starting with the leverage systems designed to speed up derailings. Less effort is needed to shift owing to the split front connecting rod, which prevents contact with the travel limit screw. Whilst the shape of the inner cage plate is engineered to guarantee maximum readiness for upshifting, the external monolith body in carbon fiber has been shaped to enhance the efficiency of the chain movement when going uphill and the readiness and fluidity in descent.
The aesthetic impact of the component is consistent with the rest of the Super Record groupset due to the use of unidirectional carbon fiber and titanium stop screws. Micro-adjustments to the front derailleur position, which can be activated by the controls, help to prevent any contact with the chain, even in the case of maximum crossover. As regards compatibility, the new Super Record 12x2 Speed front derailleur allows the use of hoods measuring up to 32 mm thanks to the new upper connector rod and the double fixing position of the control cable.
