This crank set is for you taller riders or those who prefer taller gearing. The crank arm length is 175 mm with 52-36 chain rings. This crank set came new on a Specialized Tarmac in September of 2023. The crank set has approximately 10K miles on it. There is a fair amount of cosmetic damage from shoe rub. This can be touched up with a black Sharpie (I did a very small patch to demonstrate on the drive side crank arm shown in one of the photos.) Also touch up paint is available for around $20US (Legend Wheels touch-up paint for Shimano Ultegra 8100 groupset.) I am selling this crank set because I changed to a 172.5 crank arm length with 50-34 chain rings.
