|Anybody try Weyless Carbon road cranks?||853|
Feb 13, 2002 8:44 AM
|Thinking about buying these instead of Dura Ace.
Any problems with these?
I heard that they are the same as FSA only relabeled.
Is this true?

|50g over claimed weight||Martin|

|Supergo claim they weight 410g but they weight 460g (both arm + spider). They also claim a complete setup of 554g while it's actualy 597g. So they're not much lighter then dura-ace. Since they are not pricy they might be condidered for the nice look they have! I think they're pretty stiff but i can't compare to dura-ace since i haven't try them.
I don't think they are the same as FSA. According to Damon Rinard's weight list, FSA are a lot lighter.

|The Weyless cranks are
i carbon wrapped alloy cores.
The FSA cranks are all carbon.

|Since it is cheaper than Dura Ace I would prefer Carbon Cranks. But, if it is flexier then I prefer stiff and will get the Dura Ace. This is why I am asking your opinion on the quality of these cranks. Maybe being alloy center wraped in carbon would make these extra stiff? I don't know?|

|FSA Carbon Pro Cranks...||Xeke|
Feb 14, 2002 12:28 PM
|... are but one model of cranks (but the only carbon models) available from FSA. They have several models of CNC'd alloy cranks for road, cyclocross and MTB along with a number of other after market products (BBs, chainrings, headsets, etc). Their Carbon Pro cranks are available for road, tandem and triples. But don't believe me: http://www.fullspeedahead.com|

|Sometimes websites do not give all the facts. Sometimes they are outdated. There are tow models of Carbon fiber road cranks made by FSA: The Road Pro $299. 572 grams and the Team Issue $399. 535g. They are very different cranks.|

a Taiwan built crankset with an alloy spider and carbon
cranks, the Carbon Pros (as seen at Colorado Cyclist among other catalogs). The FSA agreement contains contains a clause that prohibits FSA from revealing the name of the manufacturer.
You are quite right.
cranks. Back to original Q: Same as the Weyless cranks?
Feb 15, 2002 9:29 AM
|I wonder if the Profile's are also the same? Aluminum spider, aluminum skeleton etc. They do not look exactly alike in the pics.|
|DA crank arms are 420g, 560g without crank bolt= much lighter||str8dum1|

|Just out of curiosity, where do you get your wieghts from. I tried very hard to find this same info and could not. I noticed you seem to be quite the tech guru. Are you a mechanic or a Shimano employee?|

gives you the real weights for things
you would probably need to subtract rings weight. Its a mess. There is a whole bunch of crank weights, and I am still confused with crank lengths, w/ or w/o rings and/or bolts and washers. For Durace cranks, there are at least 5 different ones with different lenghts and other bull. Its too painful to figure out the weights of things, I will just ride my ultegra cranks till i get a new bike with durace.

|I just purchased the Profile cranks and took them to work to weigh on the very accurate electronic gram scale. I have the 172.5 and they are a bit lighter than claimed weight. 420 cliamed;347.69 actual. The cranks plus spider = 430.95 grams. They only cost me $239. for spider and cranks at my local bike shop. Seems like a pretty good deal to me. Now we will see how flexy and durable they are.|

|Hi, I'm Doug from FSA.
This is quite an interesting thread. Allow me to inject some facts.
Concerning Weyless versus FSA, while our carbon arms are similar, and are made by the same sub-contractor (Gigantex), the two cranks are quite different.
At FSA we produce the spiders, chainrings and all bolts and hardware. Additionally, we do all the machining on the arms such as making the pedal hole and the bb spindle hole. We are quite confident that because of our in-house capabilities and abilities to finish these cranks that the end result is a superior product.
In this comparison, less expensive translates to "cheaper".
The next point is that this type of crank should not be termed "carbon wrapped". While the arms do use an aluminum inner spine, the arms are more like a sandwich construction using two separate layers of composite foam as well as two separate multi-layer carbon fiber layers. The aluminum spine is used to ensure proper alignment between the pedal and spindle holes.
Weight - Carbon Pro cranks weigh 575 grams and Team Issues weigh about 550 grams. Team Issue cranks have an all carbon spider, whereas the Carbon Pro uses an aluminum spider.
The Bonjour Team in France is currently using both models of cranksets on their bicycles.
Hope this information helps.

|Your information is very helpfull. It is nice to get the facts straight from the horses mouth. One subject that did not come up is stiffness is there any info on differences between FSA and Shimano?|
Feb 19, 2002 8:28 PM
|Yes, we have done some stiffness testing comparing Carbon Pro, DA, and Record. We tested for lateral, torsional and longitudinal stiffness.
Generally, the Carbon Pro's are 10-15% stiffer than the others. We have yet to do this test on our Team Issue. However, based on other things we know, the Team Issue should show even greater degrees of stiffness. The Carbon Pro we used in the testing was an Octalink crank so it is a bit of apples and oranges as compared to the square taper Campagnolo. But that's the way they're made.
Finally, even though our testing is done in a laboratory/controlled setting, we are confident that the test results represent how the various products compare/perform in real life use.
