I purchased a Specialized M2 S Works hard tail mountain bike in 1991, cracked the top tube 8 years later in 1999, and the LBS/Specialized made good on the lifetime warranty, albeit with a small twist, which I was perfectly happy with. Since the M2s were out of production, they gave me the original purchase price of the M2, $1,200 or $1,300 in credit I believe, towards any other Specialized mountain bike the dealer had in stock, with no restrictions on whether it was a bike on sale or not. So I then purchased , in 1999, a top of the line S Works Full Suspension M4 mountain bike with a 5 year warranty, which later was retroactively changed to a lifetime warranty when Specialized went back to lifetime warranties.threaded said:So, you get a crack in your frame: see how far you get arguing the difference between a manufacturing defect and a fatgue failure. Do a Google, I'm sure there're lots of people whinging about this distiction on Cannondales and the other manufacturers that similarly use fancy words.
I then cracked a chainstay tube on this M4 FSR bike in 2003, and the dealer/Specialized replaced both chainstay tubes free of charge with the new improved, stronger chainstays. In 2005, six years after I purchased the M4, I busted a flange on one of the hubs. Again, the LBS/Specialized gave me a better replacement hub for free. I purchased new spokes to fit the new hub. Total cost for the new hub (free), new spokes and labor to lace them to original Mavic 517 rim was $63.00.
Just about one month ago, I busted a flange on the rear hub of a Bontrager Race Lite that came on a road bike I purchased in spring of 2004. Bontrager has gone back to 5 year warranties, retroactively, and the LBS/Bontrager/Trek gave me the choice of a brand new Race Lite rear wheel for free, or upgrading to a Race X Lite wheel for the difference in retail cost between the two rear wheels---$150.00. I chose the latter option, and now have a newly designed 2008 Bontrager rear Race X Lite wheel that starts over with a new 5 year warranty.
I think you are absolutely right that warranties can be tricky to collect on, but with certain manufacturers, combined with you personally having a good relationship with a LBS where you initially purchased the bike, which said bike shop also has a good, solid relationship with the manufacturer, you can indeed sometimes collect on these warranties as I have done above.
