My new GAS GAS TRAIL 3.0 mtn bike had a FSA branded headset installed. After 80 miles this FSA started clicking a lot which was disconcerting. A forum recommended this brand top and bottom so I purchased and it installed very easy, as the bearings were apparently exactly the same size - so I could retain the original bearing holders (races? not really a race in loose bearing terminology). I tested back and forth a few times to confirm using my hand, perfect. Installed using the original races and its been fine now for 150 miles or so.

Je recommande cet article vendu comp’et cuvette inférieure cône de fourche fendu pour le mettre en place sur le pivot donc démontable facilement pour le monter sur une future fouche le cône est équipé d'un joint sur le pourtour qui empêche l'eau de rentrer afin de garder le roulement en bon état
