kittycat,
I rode a Bianchi Eros for five or six years and loved it until I began to notice that my cycling experience was exceeding the design limits of its geometry. I then began looking for my next bicycle.
After about two years I went to ride a Lemond Zurich at a local bike shop. I was unimpressed. I was invited to try a Gunnar Tirebiter (a Waterford brand) and was still unimpressed but thought it was modestly better than the Zurich. Lastly, I was invited to ride a Serotta csi. I was blown away. This was the bike I was looking for all my life. It was the bike I would be looking for in 5 or 6 years after I had purchased the bike I was presently looking for.
To make a long story short. Serottas are great bikes. You will be hard presed to find a better bike. Maybe you can find a similar great bike, but better? Serotta has been making bikes for more than 30 years. They have continously worked at improving the ride and handling of their bikes. They have numerous patented features they were responsible for introducing to bike manufacturing.
Had I purchased the Serotta instead of the Bianchi in the beginning I probably never would have known what I was getting. It could have been a very expensive mistake if my riding had not followed the path that it did.
If you know what you want in a bike, go ahead and buy an expensive bike and get a good fit to get the right bike. If you aren’t quite sure what you want in a bike and don’t know to what degree you will continue in the sport you could be buying a bike that you will never be able to appreciate. Your riding will just never advance to the level that will bring out the special nature of an expensive bike.
Lastly, as Tom so well stated, fit is everything. If a bike fits well, it will be enjoyed by the person riding it. If it fits poorly or not very well, the rider’s biking experience will suffer and so will their enjoyment of cycling.
Last lastly, I doubt that you will be able to find many people who own a Serotta and don’t like/love their bike.
Oh, by the way, I’m biased. Consider my comments as such. I own three Serottas. All steel frames. The first purchase experience was so fantastic that as long as it could be duplicated, I was in. You go with what you know!
I hope you enjoy your new bike as much as I have loved mine. Hope to see you on the road sometime to say hi and discover what bike you purchased.
