Years ago I unintentionally (I swear) started a shit storm with a negative review about a carbon frame that I had from a then small-ish boutique company. A few others that owned the brand had had similar cracking issues and a well-known WW forum poster and builder had told me privately later that he had warned the company against using the specific modulus they had as it was stiff and light, but brittle.
When I posted my build thread debacle I again received around a dozen PMs of horror stories from owners or friends of owners for that builder. Since then I've had three acquaintances and myself have massive delays and cracking/QC issues from a boutique component and frame builder.
Yet no negative reviews anywhere on the internet. I get it, we shouldn't roast the builder as an improper review could really sink them and sometimes things happen that shouldn't. I regret wording my Guru review as harsh as I did as that ended up becoming a distraction from the key issue.
When someone wants to buy a high end or boutique frame it's rare that they will always have the ability to take a bunch of time and find owners on various forums and solicit questions. Most boutique sales go to people that don't post on forums as is. So with no unofficial record online, these people could spend a shitload of time and money on something that might have a decently high problem rate yet no documentation of it.
Forums aren't supposed to be the Yelp of bikes, but this info should be shared. There is a way to do it- something that is more proper than what I did, but what is it? After hearing another person have an expensive, lightweight custom component crack (third in total) I went to look for reviews of similar occurrences and just found postings from the same fanboys over and over. This really skews the market when the same forums have hundreds of posts that roast Specialized and Trek, who actually publicly acknowledge their issues and rectify them for customers.
I dare you to buy the Allied Echo frameset. Double dare you.
