    Spin it right 'round.

    Oval chainrings have a dedicated following but, kinda like licorice and hippity hop music, they aren't for everyone. Rotor made its name with ovalized rings, but the Round Road Inner Chainring is, well, round, so traditional riders can enjoy Rotor's durability without having to leave circularity behind. The Round Road is made from burly 7075 T6 aluminum, comes in three sizes, and has different bolt circle diameters depending on size.

    Crankset update

    • Familiarity: I've put it through the wringer

    I have a 20 year old Ultegra crankset and converted from 8 to 11 speeds in the rear. Changed out the front chain rings to Rotor assuming they would work better with the narrower 11 speed chain. They shift beautifully and look great.

    Cheap EPO

    • Familiarity: I've put it through the wringer

    I have this on one of my bikes and now getting it installed on my other bike. I'm not a strong climber. After having it installed, my friends accused me of taking EPO.

    Unanswered Question

    I see the sizes listed as 36, 39 and 44 in the dropdown list above, but the description lists 34, 39 and 44 tooth options. Which is correct - 34 or 36?
