Sorry CannonEvo48, but there is just no way your frame weighs 499 grams. In fact, it probably doesn't even weight 599 grams, perhaps not even 699 grams. Recheck on another scale, preferably at a shop, with the units set to grams and the scale zeroed properly.
Just for some perspective. 499 grams would be the lightest rideable road bike frame ever made, custom, production, whatever, and by a comfortable margin of around 130 grams. Think about that one
sure...that's easy...take the whole bike apart again.....probably not....
anyone else purchased a 48 frame not built up yet? maybe we can get someone else to weigh in....
It's not easy, and it's quite a lot of hassle. But it isn't 499 grams. Either your scale sucks or you zeroed it improperly, sorry. Go and call Cannondale USA, they'll laugh when you say your frame weighs 499 grams. It would weigh that if it was missing a chainstay and a seatstay. There aren't many 48 cm owners who have weighed their frame, but quite a few people in this thread and forum have 52's. Even if they subtract 100 grams (more than the true difference) to make the difference between a 52 and a 48, it won't be anywhere near the 499 gram range.
