There are times when a simple, cost effective chainring is exactly what you need to finish a singlespeed conversion or a commuter project. 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.

With so few options for quality rings that you can retrofit to older 104 bcd cranksets, these rings will be a pleasant surprise. Available anodized in black with a few gearing options, you will be able to get these mounted up and be riding in no time, so if you have a 4-arm mountain crankset with the 104 bolt pattern, you have found your chainrings.
