Finally!
After 5 months of waiting for parts, decals and some other problems, the bike is ready to ride again!
I had to change the whole group set, and I opted for the Shimano Alivio with v-brakes.
Also changed the wheels Araya, that were already well beaten by Vzan Extreme wheels and Continental Race King 2.2 tires. I really liked the bike finished. I think it looks better than when it was new! lol
Special thanks to EarlofBarnet, who appointed the guy who had the decals to sell. Gil, the guy with the decals, very nice guy. And my uncle Pedro and his son Jonathan, who did all the work on the bike.
Thanks to all.
