I must say in the time frame when I sold and serviced the Windsors, Carabelas along with the other pro bikes, I grew to see that while the Mexican bikes were great values and reasonable riders, the craft and workmanship was much lower than the top standard as set by the famous builders. Even Colnagos, when their origins were questionable, surpassed the Windsor quality. That doesn't mean they are bad bikes and the owners shouldn't enjoy them.
Canopus, by the way, was a Columbian bike brand. I would rank them right up there with Windsor pros! I always thought the name similarity to cannabis was funny given that country's most famous export..
