Tern 100 mm Fork

fits Dahon as well

140 mm steel steerer tube.
This is a full steel fork, heavy duty strong. For Disc brakes. Has the braze ons for fenders and lowrider, a nifty cableguide for the disc brake cable, International standard disc brake mount and a holder for the magnet. This fork has a 100 mm old ( over locknut dimension) and hence works with regular front hubs. This fork was developed in Switzerland and is the perfect upgrade for loaded touring or simply if you wish to add a powerful disc brake to your bike.
ThorUSA is the exclusive seller in the USA for this fork and we had to twist a couple arms to get them for you.
