Motobecane True frame Weight!!!(9 posts)

Motobecane True frame Weight!!!G3JONES
Mar 2, 2003 1:55 AM
After I decided to strip my Motobecane Le Champion bike I checked the weight on my 58cm frame. Weight is 3.7 pounds. Not too bad but Motobecane dealers are very misleading. My Local bike shop who I wish to remain nameless said the weight was 2.8 pounds for my frame. After I told him the true weight, he wasn't very happy. He blames Motobecane for misinformation.

If anyone from Motobecane reads this please let your dealers know the true weight. One positive thing about motobecane is they did write on their web sight:

Kinesium Aluminum
A special formulation of 6000 series aluminum. Double butted series aluminum. Double butted and formed for incredible ride quality. Frames as light as 2.8 pounds.

I am sure they mean 2.8 pounds for the 50cm frame and not the larger ones. I plan on selling the Motobecane frame and Kinesis fork in the classifies next week.

I am planning on building a carbon aluminum frame. I am thinking of buying a Quattro Assi Alu Carboeo Frame on eBay. What do you guys think?

My friends team rides the Quattro Assi and I have heard all positive things about them other than the loose fitting integrated head set that was replaced by Quattro Assi.

I'd blame the shop more here for claiming that the frame was 2.8lbs (they should know better). Motobecane's ad copy is pretty similar to what most manufactures do - provide data on their lightest frame setup. To a degree, you get what you pay for. If your only beef with the Le Champion is the weight, I'd just stick with it. Is .9 lbs really going to be the thing that makes or breaks you here?
Weight, read the fine print!!! (no pun intended)Fez

Regarding weight, always read the fine print, and even then, it helps to take things with a grain of salt.

If you read Litespeed tables, they list weights for every frame size.

If you look at Colorado Cyclist ads, they usually list a pretty accurate weight for a given frame and they always list the frame size (usually a 55-57cm).

The MBK info wasn't misleading at all. It says "as light as." If you look at those who do publish weights, there can be 0.5lb to 1.0lb of variance between smaller and larger frames.

Lots of manufacturers just don't publish them at all, like Specialized and Cannondale.

Regarding small components, I have found the actual weight of everything is up to 30 percent greater than the published weight. I'm not a weight weenie by any means, but I now weigh things just to see how far off they are from the published claims to get a chuckle.
Everything weighs more than advertised!Alexx

I bought a pair of Continental Sprinters once. they were advertised as being "250g each" on the website, but the box said 275g. Well, that p!ssed me off, so I went to the chem lab and weighed the suckers. 281 and 283 g! Without the valve cap!

Well, when even a well-established company such as Continental tire (been around for about 140 years!)lies about their component weights, is there anybody you can trust?

... weighed my new CAAD5 60cm aero frame... about 3.9 lbs.
... weighed my new CAAD5 aero fork... about 596 grams (1.3 pounds).

At least I now know not to even try to shoot for a sub 18 pounds...

Be the bike.

Caad5 weighing in at 5.2lbs? Does the aero frame weigh a lot more than the road frames? How much of a weight penalty do you think a 60cm has compared to a 54cm?

I always thought Caad5-7 road bikes and all carbon slice forks were really light.
knot according to my scale...Akirasho

... the aero tubed frame seems overbuilt (plus, there's simply more metal)... indeed, I've got a bare 60cm '03 Klein Quantum Pro Carbon Team frame... and it seems silly light when compared (haven't put it on the scale yet). It's a price you pay for "aero" tubing (the shape of Dale's tubes are not a true airfoil)... but this seems high (I've got a Cervelo P2K which while not super light, is not a pig either). The fork is a pig (the Klein fork is again, silly light)... and aside from a lightweight wheelset, would be the first thing to go ('cept it looks soooooodammmnedgoood). The bike will serve primarily as a "trainer" so it's not an issue.

I suspect that the fat tubed CAAD's are still relatively light... especially CAAD7 (which probably pushes fairly close to 2.5 pounds in a 60). I think the "Slice" forks came in different "grades"... with aero (again because there's more material) being heavier.

Be the bike.
