Lightest Production Frame(15 posts)

Lightest Production FrameNitsche

How can so many companies advertise that they have the lightest production frame made? Isn't there something called truth in advertising? Could we pull off a class action suit if we purchased a frame advertised as the lightest but isn't?

Several frames could be the lightest, depending on what size, how measured, etc. Include paint, decals, etc? I know of several making the claim: Bianchi EV4, Litespeed Ghisallo, Calfee Dragonfly, Colnago not long ago claimed the C40 was, but no way now.

Calfee says it measures with no paint, which is ok on a nude carbon frame, I suppose. Paint can add 50-100 grams or so.

Weight is also dependant on frame size. A 47cm Tuscany weighs 3.1 lbs and a 61cm weighs 3.6lbs.

To REALLY determine the "lightest" frame, all parties would have to agree on the frame size.

when specified, I usually see 55 cm nmDougSloan

My 2000 ONCE TCR Team Edition frame (black anodized) frame came in at 975 grams! We couldn't believe it! Anyway, that frame cracked on the right chainstay and was replace under warranty with a 2002 Once frame that weighed 1200grams. I promptly sold it.

How many ounces is 325 grams? Is it enough to change your mind about a frame?
roughly 10.5 ounces -- roughly 2/3 of a pound...Stinky Hippie

....pretty significant
since when did 1200-975 = 325?collinsc

its 225g which is half a pound, and considering that the first frame cracked, id say its probably a half pound well spent.

I swiched because it took 3 months(!) to get a replacement so I bought another frame. So I sold the replacement TCR when I got it.
1 ounce = 28 grams nmBikeViking

Almost all frames are pretty light now...miposy

...and the overly optimistic marketing folks will consistantly claim to be lightest.

However, anymore frame weight is a pretty silly reason for most of us to buy, or not buy a frame. Normal size steel frames are consistanly less than 3.5 pounds, Ti consistantly close to or just under 3 pounds, carbon and aluminum consistantly near 2.5 pounds.

I would never, in this era, buy a frame based on weight. It's all about the ride now (and looks, frankly).

My Thermacrom Strong Frame with Daytona Groupo, Open Pro Rims, Axial Pro Tires, Titec Stem, Morph handlebars, and Speedplay pedals is only 18.5 pounds on the Scale at my LBS. That's a normal bike with normal not too spendy parts.

With Record and lighter bits and pieces, this bike could come in close to 17 pounds. How much lighter does a bike need to be if it isn't for racing?
I've seen 820 grams...Dave Hickey

Trek is the poster child for claiming "lightest production frame." Last time I had my 5900 stripped down, the frame, 58cm by Trek's convention, checked in at 2.5lb, including the lower headset cup (glued in the frame) and the shifter boss bolt that runs thru the downtube. Accounting for the hardware and slightly larger size, that's close to their quoted weight of 1040 grams or so. But still far from the lightest frame going.
