We need a Picture. The Cirque was sold as a cross bike and in fact was even a 700D wheeled cross bike one year...1990 if my memory is correct. First Aluminum frame bike GT ever did and then it went back to steel as a 700C wheeled cross bike. If you buy that thinking you'll use it as a mountain bike you'll wind up running it as a very skinny wheeled bike. Pics please so we can confirm. If it's old enough it may even take a u-brake in the rear. Is the frame blue or silver?
Needed: 26.8mm XTR seatpost, blue GT/Grundig Jersey.
