Japan bike parts manufacturer Shimano’s medium-level road racing groupset Shimano 105 is now 11-speed. According to Shimano, the new groupset also has increased breaking power.
Shimano 105 is widely popular among road cyclists thanks to its fine price/performance ratio. It also comes as the default groupset on entrance/medium level bikes of many bike producers.
Shimano has redesigned the derailleurs and shift levers and included polymer coated cables to replicate the light shifting of its higher level groupsets, Ultegra and Dura-Ace. The new 105 -5800– is noticeably lighter than the previous versions. The shifters will be available in black or silver and include the same polymer coated shift cables from Ultegra 6800.
The new Shimano 105 5800 is a model year 2015 product, and the first version will probably arrive in local bike shops on complete bikes from the major manufacturers – the expectation is for those to arrive in mid-June of 2014.
