Presented lately at the Bikemotion that closed its doors two days ago, this new chainring has a particularity since it doesn’t have any visible fixing bolt.
This chainring compatible with Shimano 105, Tiagra, Ultegra et Dura-Ace weights only 90gr and uses the new concept called I.L.S (invisible fixing system) that turns useless the chainring bolts. This saves again a few grams.
This silver or black chainring is fully CNC machinned and will come from 49 to 53 teeth.
Here are a few pictures of the new M5 rear hub and rims we already presented a few days ago.
