The RD2 Messenger is a good mid-level track crankset that fits most frames, including conversions (with wider bottom brackets).
The RD2 is actually the Sugino road double crankset converted to single speed/fixed gear use (thus the "RD", 130 BCD and wider chainline/Q-factor), however that doesn't mean it's not a great option.
Cold forged alloy arms and a stiff disc-like aluminum chain ring will work for most riders - especially those not needing or wanting to upgrade to the pricer track-specific 75.
This crankset takes a JIS square taper 103mm bottom bracket, which is not included. However, you can add a the Sugino BB3 (but don't use the incompatible Sugino 75 BB) or a Tange bottom bracket as options. For conversions, you can also get a longer BB spindle for clearance.
The black version is slightly more expensive given the more expensive anodizing process versus tke polished silver model.
Note: The RD2 and the RD2 Messenger differ by their chain ring. The Messenger has a 165mm crank arms and has a stiffer 1/8" 46T disc-type chainring (which also makes it more expensive) while the RD2 has a 165mm or 170m crankarm and the 3/32" 48T classic style chainring.
