It can be frustrating when you have an older 130 bcd crankset and need a replacement ring or rings. We get a lot of calls who want to convert an older crankset to a singlespeed or change to more commuter friendly gearing. Dimension chainrings are well made, CNC machined from 7075-T6 aluminum and are ideal for any 5-9 speed set-up that runs a 3/32" pitch chain. Ideal for singlespeed use, the rings are stiff and hold-up well under constant pedaling. Although there are no ramps or pins, when used in combinations for a geared set-up, you will find acceptable shifting from ring to ring.

Although there are still options for 130bcd 5-bolt spiders, most replacements available now are narrower and designed for 10 or 11 speed use. The quality and durability of these rings will be a pleasant surprise. Available in silver, you will be able to get mounted up and be riding in no time, so if you have been thinking about converting to a singlespeed drivetrain, what are you waiting for?
