I purchased some Schwalbe ONE tires from Pro Bike kit a few months ago. I always have extra tires so I did not put these on until last Thursday. Saturday ride my power meter was high, average speed not so much. Same thing today. So, I was washing my bike and noticed the Schwalbe's I've been riding for the past year all had Schwalbe 1 ONE on the sidewall. These have Schwalbe P ONE on the sidewall. Googled Schwalbe and NONE of the ever had a "P" on the sidewall. Is Probike Kit selling counterfeits. They refused to help as I bought these in May and they sat until last week,
