I'm going through a mourning process right now. Last Saturday while beginning to ride the local Lake Norman State Park trail I noticed a couple of stress cracks in the top tube of my 2006 Nomad. I was very, very surprised to say the least (as were the bike shop and Santa Cruz). The reason I invested in a Heckler and then a Nomad was for the durability aspect due to my "clydesdale" status. To the Nomads credit it did not catastrophically fail and leave me stranded as i rode out the rest of a 20 mile ride and the cracks only got a little worse.
The good news is the my LBS, Mock Orange Bikes in Winston Salem NC, got right on the job and emailed SC some pics and SC got right on it and said return/ship them the frame asap. Once received they would ship a new one. I was given a choice of a blue powder-coated one available right now or a black anodized (like my current one) would be available for shipping on the 20th. I chose to wait for the black ano as I really prefer the finish as it matches my black ano Maverick DUC32 fork and by the time they get my frame next week (going all the way across the US) it would only be a few extra days wait for the ano finish.
Many "props" to Santa Cruz for standing behind their product. Also, big thanks to MOB for all their help w/ the process and offering me a loaner that I haven't gotten so far as I "repo'ed" my Heckler from my brother! I ride between 40-70 miles of singletrack in an average week and this would have been absolute torture w/out a loaner of some sort.
