In this article I will share my thoughts about the CEMA Bearing Ceramic Pulley Wheels Shimano 12-14T that I’ve installed on the Shimano Ultegra R8170 rear derailleur of the Canyon Ultimate CF SLX 8.0 Di2.

Framesandgear Titanium Crank Arm Bolts M6x19 Black
In this article I will share my thoughts on the Framesandgear Titanium Crank Arm Bolts M6x19 in color Black, that I use in combination with the Shimano Ultegra R8100 cranks. Just like the Kogel Bearings Shimano Crank Arm Fixing Bolt these titanium bolts are -from my point of view- a good upgrade to the default bike parts.
