With a passing resemblance to the Pauls Blue Balls and Fire Balls these Tranz-X seat binder bolts are a great, value for money upgrade. With machined rounded end caps and a fairly long M6 bolt these will fit most bikes and the bolt can be replaced for a longer or shorter one, or even a titanium bolt.
- M6 diameter bolt
- Max internal width (across outer part of seat clamp lug): 30 mm / Min width: 17.5 mm
- Weighs 20 grams
