<p><span>These Japanese-made Sugino chainrings offer up a simple and high quality 3/32 option for your single-speed, fixed-gear or internally-geared rig. The perfect choice for that old road frame you are converting, these 5-bolt, 130 BCD rings fit many standard road cranks from the 10-speed era. The 3/32 nature of these rings also lends them to usefulness in terms of replacement rings for some older 5/6/7/8-speed drivetrains. There are no ramps or pins, but if those old friction shifters still float your boat, these will work just fine!</span></p> <p>Hey! Don't forget chainring bolts!</p>
