Description
Coming from legendary Japanese manufacturer Sugino, the RD2 Messenger is a good mid-level single speed/ fixed gear crankset that fits most frames, including conversions (with wider bottom bracket spindles).
Cold forged alloy arms and aluminum chainring will work for most riders - especially those not needing or wanting to upgrade to the pricer track-specific 75. Given it is a converted road crankset, it also has a wider Q-factor of 45mm to work with lots of different frames (including the Wabi Classic and Thunder).
Note that this is the 1/8" version. There was a 3/32" version, but it is being phased out by Sugino.
Specs:
- Chainring BCD: 130
- Chainring Teeth: 48T
- Drivetrain Speeds: Single Speed 1/8"
- Spindle Interface Type: Square Taper JIS
- Bottom bracket length: 103mm (not included)
- Color: Polished crank arms with a blasted silver chainring.
- Weight: ~565g
- Chainline : 45mm
Notes
This crankset takes a JIS square taper 103mm bottom bracket, which is not included. However, you can add the Sugino BB3 (but don't use the incompatible Sugino 75 BB) or a Tange bottom bracket as options.
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 1/8" 48T classic style chainring.
