why discs? just pop a disc on the fork and V on the back or hydrolic if you really want the power, could get a mount brazed on for not alot as their is no painting.
price is almost as low as i want to got, its going to be £12 to post unless you can collect from oxfordshire and i have dropped the price pretty quickly just to sell, but happy to keep it to build up at some point as i am a bit of a GT Fan aswell, just trying not to get the retro bug after selling my 1998 Rotwild and 1996 GT tempest, still have a 1996 avalanche but my first bike was a 1994 GT Karakoram.
price has just dropped to £80 posted, if you want to make me an offer we can see but it is a posted price at the moment.
