My "legendary" Specialized warranty experience goes like this:
The brain shock collapsed on my 2009 Stumpy Expert Carbon during a flattish XC ride. I took the bike to the dealer who removed the shock and sent it to Specialized who said "Yep, it's a warranty repair but, as the bike's nearly a year old and is probably very near to doing 1200km, you need it serviced. So, pay up £130 and we'll fix it while we service it."
"No," says I "I always ride with a Garmin and the bike's only done 600km and is 10 months old. This is much less than the service interval shown on the paperwork that came with the bike."
"Ah, we changed the service intervals and put this in an addendum to our service manual"
"So, where is this addendum?" I asked
"On our website." they said.
After much searching, I found it under Stumpjumper 2007 models and it said it applied to 2007 to 2009 models. It wasn't listed under 2009 model manuals. They didn't give me the addendum when I bought the bike or send it when I registered it on their website. And they continued to insist that I paid for the shock to be serviced. I caved, paid up and it arrived back.
The top cap assembly of the Brain was completely different - clearly redesigned - on the returned shock.
