Information about Olympia bicycles There is a bicycle dealer in my area selling "Olympia" bicycles. I haven't seen any athlete riding those bikes and I was unable to find any reviews on the internet. I know that the company is one of the oldest ones in Italy.
What I want to know is where do the Olympia bicycles stand in comparison with the other top brands like GIANT, Trek, BMC e.t.c.
Olympia bicycles are as good as any, and the company has been doing for about 100 years longer than any you mention.

Having said that Olympia produce good bikes, they have a different brand for pro-level equipment: Scapin, one of which I am privileged to ride.

I gave an Olympia to my brother-in-law, three years ago. He's been riding it 500 km per month ever since without problems.
