The Front train hold of 5 mm is the precision setting tool par excellence for the chassis of the group OTK. It settles on the rocket of 25 mm (Senior standard) between the hub and the eccentric rings.

It is this small ring that will allow you to change the width of your front lane with finesse. In karting, every millimeter counts: switch from a 10 mm hold to a 5 mm hold can release the front train and allow the kart to "rotate" more easily in tight pins.

The BSS front train holds are essential adjustment components for group chassis OTK (Tony Kart, Kosmic, virtually known ...). This model of 10 mm is designed specifically for rockets 25 mm in diameter. They allow to change the width of the front with absolute accuracy, directly influencing the reactivity and grip of your kart into a turn input.

Manufactured according to quality standards OTK, these holds offer perfect flatness to avoid any constraint on your hub bearings
