Super-special spherical seat system
Walking the aisles of Interbike, it’s easy to slip into sensory overload and develop a bit of tunnel vision. Every once in a while, though, something unique tugs from corner of the eye, meriting a pause and a photo. Something – for example – that looks like a Pulstar hub bearing fruit.
Not a new idea, Cole’s second-generation spherical Dynamic Spoke Alignment (DSA2s) design consists of spherical spoke anchors on a straight-pull hub. The idea is to allow for the same hub to be used on any wheel size without the spokes binding in their holes. The little blue spheres self-align with the spoke angle, spreading forces over a greater area than a potentially mis-aligned spoke head could alone while reducing bending stresses on the spokes themselves.
While it’s easy to poke fun, we’re glad that there are people out there thinking about things that would probably never occur to us. The DSA2s design is available on Cole’s carbon fibre Ibex 26, 27.5, and 29er mountain wheels as well as a couple of cyclocross models. The 26in model is a 1,430g/23mm tubular, the 27.5 a 1,680g/23.5mm clincher, and the 29er a 1,640g/27.5mm clincher.
Cole lists Evans Cycles as their UK distributor, but Cole’s wheels are no longer available on Evans’ website. Cole has new UK distribution in the works: look for news later this winter.
