The PTBi (Premium Tillett bracket inwards) bracket system is designed to tuck under the seat to give a minimum footprint. This aids fitment into narrow and restricted cockpits. The PTBi brackets are made from high grade anodised black aluminium and are 6 mm thick with a beautifully machined edge and engraved logo. The brackets allow the seat to be tipped, raised and lowered using the various hole and slot combinations.
2° race brackets
The 2° brackets models can be used with the B6 Screamer, B7, B8 and B9 seats. They also fit the side mount versions of the standard B6 seats and the W series seats when made with the additional back frame moulding.
