Seat [25cm Leg Length Adjustment] Double-Locking Mechanism

The Tillett STRI is a double-locking adjustable seat runner set designed to provide 25 cm of leg length adjustment for road car use. This runner set is intended to be used in conjunction with various Tillett seat brackets, including TB1, TBF1, TB2, and TB3, and can also be mounted directly to the bottom of certain Tillett seats like the W1, W2, W3, and W4 (when equipped with an optional back frame), as well as the standard B6 seat (requiring a TK5 spacer kit for bottom mounting). Side mount brackets are also needed for compatibility with seats such as the B6 Screamer, B6 XL Screamer, B7, B8, and B9. The STRI runners have a hole-to-hole spacing of 31.5cm, aligning with most Tillett seat brackets. The product has a weight of 1.38 kg.
