Good afternoon; newb warning.
I'd like to decrease the number of teeth on my chainring. The current ring is a Sugino Messenger 42t and says 130 pcd on it. In looking around, it seems the smallest ring for 130 pcd is 38t, but i know nothing about chainrings, especially single speed chainrings.
My understanding from reading here is that any 130 pcd ring that is non ramped and has 5 holes will work with my crank. (Example: http://www.amazon.com/Rocket-Alloy-N.../dp/B000BMT2I8)
So my questions:
1) is my understanding correct?
2) Is changing the ring simply a matter of removing the 5 bolts, swapping the ring, and replacing the bolts?
The reason i'm looking for smaller rings is that i put an Alfine hub in the back wheel and want access to substantially lower gears than the current 42/19 allows.
Thanks in advance for your help!
