I recently purchased a pair of these tires in size 700x25c from Real Cyclist, and they are 66 TPI. I purchased a pair of 700x23c from another supplier, and they are 127 TPI. I am new to Hutchinson tires and not familiar with this discrepancy. Hutchinson's website states that both sizes are 127 TPI. Therefore, I suspect that these 66 TPI tires may be last year's model.
