That sounds frustrating, but it’s good that they’re offering a replacement. Shimano Deore cranks are a solid choice—reliable, durable, and widely used for trail riding. They might be a slight downgrade in weight compared to RaceFace, but they’re generally tougher and less prone to issues like stripped threads. If you’re not too concerned about a small weight difference, Deore should serve you well. Just make sure they install everything properly to avoid future issues. Enjoy the Cypher SE—it's a great bike!
