Outsized derailleur pulley cages are sometimes upgrading the bearings and pulley dimension, and there are many choices. The brand new Token Shuriken for the most recent Shimano Dura-Ace R9200 and Ultegra R8100 take 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 their 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 scale 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 sublte, perhaps solely 6-7mm, however it’s sufficient. Offset higher pulleys are nothing new, they’re used on wide-range mountain bike and gravel drivetrains to assist deliver the pulley additional down as you shift into larger cogs, thereby permitting extra room whereas letting fashionable derailleurs use a extra steady 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 the complete gear vary whereas permitting them to run larger pulleys for higher system effectivity.
Token’s Shuriken makes use of a 13-tooth higher pulley and 19-tooth decrease, each with ceramic bearings. Against this, Shimano’s inventory 11-tooth pulleys appear puny. To be honest, the brand new Shimano teams shift extraordinarily properly, so I’ve requested a Shuriken to check on the brand new group.
Weight is midway between Ultegra and Dura-Ace, pricing TBA (replace once we get it).

Token S-Field & M-Field stealth routing headsets
Very similar to 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 incorrect with these).
The S-Field and M-Field headsets are for street/gravel bikes (proven above) and mountain bikes that use the 1.5″ higher and decrease headset cup requirements. Prime caps and spacers permit cables and hoses to run into the headset whereas utilizing an ordinary stem and handlebar.
A wide range 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 their Rotation Block that limits how far the handlebar can flip so it doesn’t smash into your high tube if you happen to wreck.
They’ve additionally up to date a few of their wheels with hookless rim profiles for simpler tubeless setup. The ROUBX G33 (proven above) is their 33mm deep gravel wheel with 25.3mm inner width. Above it’s the Konax Tri Disc with 76.3mm deep aero rims.
