Overview
A compact road double's larger ring is the part on offer, an aluminum chainring on a five-bolt road pattern. The black finish matches a SRAM road crank.
Riders who need a replacement outer ring get an aluminum part in a standard road size. Bolts, the inner ring and any crank arms are separate, and the title mentions a pairing with a smaller ring.
Who it's for
Road cyclists with a worn outer ring on a matching bolt circle will find a clear replacement. Anyone starting from scratch needs a crank, a bottom bracket and bolts as well.
Pros and cons
- Standard five-bolt road pattern
- Bolts not listed
- Not a crankset
- Thickness only in title
Performance notes
A bigger ring gives a taller gear, so each pedal turn moves the bike further for fast flat riding. Aluminum teeth wear faster than steel, so a worn chain will accelerate the damage.
