The microSHIFT Arsis11 is the latest instalment of microSHIFT's top-of-the-range Arsis model line. Unsurprisingly it is an eleven speed mechanism.
It has many of the usual features - carbon wrapped outer parallelogram plate, pulley wheels with sealed bearings, titanium small parts, aluminium hanger bolt etc.. But it lacks some of the CNC bling of earlier versions - it is cheeky to say so, but something about its look and even about the logo seems more Ultegra than Dura-ace.
In the modern style, the pulley cage is 10mm longer than on previous versions, but, surprisingly, the weight stays the same.
