Excellent external bearing bottom bracket crankset. The SRAM Omnium has been discontinued but this is a brilliant 130BCD alternative. If you must have a 1/2x1/8 chainring, there are plenty of robust chainrings available. I choose to stay with the 3/32nd chainring included with the S300 and used a Connex 808 double (inner and outter links) nickel plated chain. I'm also using an ACS 4 paw freewheel. This is the perfect replacement crankset for my Felt Dispatch single speed project.
Got this to replace my old crank that broke. (Is essentially the same make/model.) The high-gloss black matches perfectly with my Rohloff Speedhub, Mavic rims, and Issi pedals.
