Hmm. Had a feeling bird would receive some love. A friend of mine was told that 2.5 years was a lifetime as far as an aluminium frame was concerned. Original owner. I wouldn’t buy from them.
Bird’s disclaimer:
IMPORTANT NOTE: All aluminium frames will accumulate fatigue over its lifetime and this will vary the depending on the alloy, frame type and amount of use the frame is subject to. Use in competitive events, jumping, riding with heavy loads, commercial activities and other types of non standard use can dramatically shorten the useful life of the frame and we reserve the right to take this into consideration when assessing a warranty claim.
Is fair to be honest and I suspect most manufacturers with lifetime warranty also have similar disclaimers.
Doesn’t mean it won’t last longer than 2.5 years though. Plenty of ali frame bikes out there going strong much longer (have a Santa Cruz ali frame at 8 years or so no problems, and it didn’t have lifetime warranty back then either).
Burden of proof. If you can prove it was a manufacturer defect, then no worries. Regardless, you’ve got 6 years under statutory rights in UK also, burden on proof on yourself of course after 6 months.
