GCB Upside Down fork repair kit
The GCB front forks with 43mm inner tubes are obsolete, but we still offer these complete fork repair kits. Included are 2 oil seals, 2 dust seals, all replacement O-rings and slider bushings. Sorry, no inner tube guide bushings as these are obsolete.
Note: We recommend SAE 10 fork oil for normal road use, or SAE 20 for more extreme road or race use.
