Specialized Levo - Broken tooth on cassette (SRAM 1130)

Bike is 6 months old / 150 miles.

Noticed some noise during the last ride and it appears that a tooth on the cassette's 5th cog has completely snapped off. (Not profiled!)

It's SRAM 1130 gear.

LBS is unhelpful. They tell me they need to send the cassette off to the distributor and get their view before I can be offered a warranty replacement. So that would mean hand over the cassette, no bike for a month...and even then they may refuse a warranty replacement if the distributor says "no".

Any views? - Bad luck on the trail or defective cassette / drivetrain? I read somewhere that some groupsets can't handle the torque from the Levo motor.

And is my LBS's reaction typical for a warranty claim?

    Buy a new cassette while your current one is away. Hopefully you’ll then get a warranty replacement to keep as a spare.

    Who knows how it happened: defective manufacture, struck by something, debris in the chain. It looks like the tooth to the left of the missing one is damaged as well. I doubt it is the cassette’s inability to handle the power of the motor. If it was then there would be many tales of woe.

    It's electric bike? Generally when changing gear you want to remove load off the chain, especially when climbing, when pedalling that is done by not pressing as hard, an electric motor won't do that for you.

    I doubt that is fault of the cassette so unlikely to be honoured by the warranty.

    Just unfortunate gear change broke it.

    Gear changes under load usually do for the chain not the cassette, but yes may be contributory.

    As above, just get a cassette and if you get one under warranty keep as a spare.

    E-bike (legal) and not that fit a rider is little more power than a fit rider, and if you are fit why have an e-bike!

    It's a five grand bike and you don't want to buy a spare cassette to keep it on the road ?

    150 miles in 6 months? Doesn't sound like you'd miss it much...
