(p.s. I did do a search before creating this thread, and didn't find an in-depth enough discussion to satisfy this question, either here or on the broader inter-webs).
Stradalli is a Miami-based company that sells carbon frame bikes that are both a) cheap and b) very light. Sounds too good to be true, but perhaps their direct-to-consumer business model + streamlined manufacturing means they can pass enormous savings on to the consumer.
One thing that has come up among people who have used Stradalli (or have thought purchasing Stradalli) is that they have a recommended rider weight limit on their frames. For instance, the RD17 has an approximately 175 lb. weight limit. Which seems quite light for many riders.
I looked up their explanation on the warranty, and here's what Stradalli says:
Weight Limits: Carbon Material use is optimized to deliver both light weight and specific performance. You must understand that these types of bikes are intended to give an aggressive racer or competitive cyclist a performance advantage over a relatively short product life; a less aggressive rider will enjoy longer frame life. Choosing a lightweight carbon frame you are choosing a light weight (shorter frame life) over more frame weight, more dent resistant, rugged frame with a longer frame life.
Most Lightweight Carbon frames are designed to support 180lbs of rider weight. Carbon wheels and bars rated up to 250lbs. All frames that are very light need frequent inspection. These frames are likely to be damaged or broken in a crash.

Correct me if I'm wrong, but I've never seen this kind of a warning about lightweight frames from other manufacturers. But it got me wondering: is there an unstated weight limit about other lightweight carbon frames from other companies, that Stradalli is simply being upfront about (as their wording seems to imply), or is it simply that Stradalli's frames are lightweight by thinning the carbon more than other companies, making up for not the most advanced fabrication techniques by simply shedding material?
In the case of the former, this seems like an industry wide safety issue. In the case of the latter, it makes me wonder if I should consider Stradalli frames safe at all, even at a svelte 140 lb and well within their recommended weight limit.
What do you think?
