Oversize derailleur pulley cages are usually upgrading the bearings and pulley measurement, and there are many choices. The brand new Token Shuriken for the most recent Shimano Dura-Ace R9200 and Ultegra R8100 takes issues a bit additional by offsetting the higher pulley’s place to optimize the chain’s place relative to the cassette.
All the opposite options that make its OSPW system distinctive are right here too, from the ultralight carbon fiber cage to the chamfered tooth profiles that make surprisingly little contact with the chain to cut back put on and noise. Right here’s the way it works.
The higher pulley is offset barely from the cage’s pivot level. It’s refined, possibly solely 6-7 mm, nevertheless it’s sufficient. Offset higher pulleys are nothing new, they’re used on wide-range mountain bikes and gravel drivetrains to assist deliver the pulley additional down as you shift into greater cogs, thereby permitting extra room whereas letting trendy derailleurs use a extra secure horizontal articulation.
With Shimano’s top-end cassettes now coming in solely two (traditionally) massive 11-30 and 11-34 choices, the street cassette has as much as a 23-tooth hole to cowl. Token says this new Shuriken’s offset design retains the chain nearer to the cassette throughout your complete gear vary whereas permitting them to run greater pulleys for higher system effectivity.
Token’s Shuriken makes use of a 13-tooth higher pulley and 19-tooth decrease, each with ceramic bearings. In contrast, Shimano’s inventory 11-tooth pulleys appear puny. To be honest, the brand new Shimano teams shift extraordinarily nicely, so I’ve requested a Shuriken to check on the brand new group.
Weight is midway between the Ultegra and Dura-Ace, pricing TBA (we’ll replace after we get it).

Token S-Field & M-Field Stealth Routing Headsets
Very like the new Ritchey headsets, Token is seeking to present extra choices for body producers and builders past FSA and Deda (not that there’s something improper with these).
The S-Field and M-Field headsets are for street/gravel bikes (proven above) and mountain bikes that use the 1.5-inch higher and decrease headset cup requirements. High caps and spacers permit cables and hoses to run into the headset whereas utilizing a normal stem and handlebar.
Quite a lot of components and spacers assist it match brake hoses, shift and dropper publish cable housing, and shift wires, whereas nonetheless letting you get the stack peak the place you want it.
The M-Field and B-Field for mountain bikes (together with e-bikes, with slots for bike-powered gentle and laptop wires) are available two variations, one with its Rotation Block that limits how far the handlebar can flip so it doesn’t smash into your high tube in the event you wreck.
Token has additionally up to date a few of its wheels with hookless rim profiles for simpler tubeless setup. The ROUBX G33 (proven above) is its 33mm deep gravel wheel with a 25.3mm inside width. Above it’s the Konax Tri Disc with 76.3mm deep aero rims.
