JONAS3: Kupodivu k tomu přistoupili prozákaznicky :)
What if I have a third-party power meter installed on my crankset?
Cranks and or any Shimano products that are modified by 3rd parties are not covered by warranty, but as an exception they will be subject to this inspection. Any items that are found to fail during inspection and that are sent back to Shimano will be replaced free of charge without the 3rd Party Power Meter attached.
