I have a Specialized Allez Sport 2012. Which I purchased, new, just under 6 years ago in the UK. The aluminium frame has developed a crack in the seat tube, just above the brazed on derailleur mount.
I note the newer models of this bike have reverted to a band on front mech mount. Is this because cracks like mine are common, possibly caused by a recognized design flaw?
Whilst I understand aluminium frames have a fatigue problem it isn't the type of crack I would expect to see. The bike has done just under 10,000 miles.
Am I likely to get a replacement frame under the lifetime frame warranty. If so how long is it likely to take?
