Hubs P1100365

Chosen had some pretty shiny things in their booth this year, and as good-looking as they are, the real beauty is hidden inside. Their new super fast engaging hubs come in plenty of varieties, and the new silent hub all but eliminates friction. Also in other hub news, Shutter Precision expands their popular dynamo hub sizes to fit more of your adventuring needs…

Chosen’s 150T hub has… you guessed it, 150 teeth on the drive ring. Add to that 3 pawls with 7 teeth each and you get an instantaneous 2.4° engagement! That is slightly faster than Chris King, and again even I9’s 3° Torch hubs. They will be available in both road & mountain versions, with mountain versions using either straight-pull or j-bend spokes and the road hubs in straight-pull only.

Also lurking on their shelf in Taipei was their new Silent Hub. Though undeniably quiet, the key advantage to this hub design is that the pawls are taken completely out of the picture as you coast leaving only the friction of the bearings and seals remaining. As you can see in the animated image above (right), as soon as you pedal, the cassette body snaps the pawls into position and you’re off! These silent hubs will also come in straight-pull only for road, and for mountain will get both straight-pull and j-bend options.

Shutter Precision showed us a prototype of their 150mm dynamo hub last year and it looks like they’re ready to go to market now. Also they tell us they will have a 110 Boost hub ready soon, so those riding with the new standard up front will be able ride all night long powering lights and charging gadgets. Both hubs run on the 6v, 3watt standard and will be distributed through Cycle Monkey and Merry Sales in the states.

      It’s a pretty standard receiver for the wires that are routed to the light. At least I think it’s standard – it looks a lot like Shimano’s version of the same thing.

        Yep, as far as I can tell Schmidt’s SON dynamo hubs use the same connection.

        It’s actually a male-female coupling where the Lego brick is the exterior of the male plug. The Lego brick nubs are where the insulation of the wires end. The bare wire continues on and wraps around the end of the plug, which goes inside the female socket of the hub.

    It’s a pawl based freecoaster then? Eclat made the blind hub, and Ezra make one similar, the salt plus trapez is just an Ezra clone. My point is it’s nothing new, just a system that already exists, which is pretty poor, made in a mtb compatible package. The problem with this is the stupidly poor engagement, you have to wait on the free hub lifting the pawl, then the pawl engaging in the ratchet. I doubt there is any demand for such a hub.

    Imagine how many engagements they could get if they made those teeth even smaller! Like a microscopic file pattern. You could essentially get an instant engaging hub. Kidding in regard to the practical application of that one of course…once the teeth get tiny they’ll be less tolerant of wear and contamination, my point being that I wonder where this design falls in regard to that spectrum of real world usability.

        Halo have a similar multi toothed pawl on their supa drive hubs, they work, they have excellent engagement and they’re loud as hell. Never had a problem.

        Roller clutches are used instead of ratchets in Alfine hubs also; while a great technology, they haven’t made a big impact into road bicycles because they’re quite heavy.

        • Kernel Flickitov on

          They’re about 100g more than standard hubs, plus It’s the center of the wheel so it doesn’t apply to rotational weight. If you can’t deal with 100g you need to train harder.

    Where can someone eveb buy these? The Chosen website is garbage and all I can find are the road version…
