I have a set of Ultegra SL Hollowtech II’s in 175 with 53/39 rings. I would love to get on a set of 170’s and can either keep my rings or sell them…or trade someone who is in the ‘change crank’ modality.
After my 2nd knee rebuild I have come to the conclusion that the 170 testing I have done is going to make a big dif on prolonging my cycling career.
Thanks for any interest. I’m in Tampa if by chance you are local and want to deal face to face.
