Yes this is a Gazelle built Grand Prix in 23 1/2 frame size. The wheels are Campy Tipo with Mavic rims, Tufo cyclocross tires. The chainguard is Simplex made to play well with the Simplex Prestige front derailleur. Saddle is a Wrights, but predates the bike by 5 yrs. I added Suntour bar end shifters also.
