Part 2: Dead of rim brake road bike? NEW Upgrade Shimano Ultegra R8150 Di2 & Bontrager XXX Handle

In part 1 of this video , we shows how we complete disassemble all the components from year 2016 Trek Emonda SL 5 rim brake road bike.

In this video, we continue the project of upgrading the gear components which is Shimano Ultegra R8150 Di2 (rim version) groupset and Bontrager XXX VR-CF Carbon handle bar.

In fact, installation of rim brake components take slight longer time than disc brake as we need find a way to keep the cables neat and not too length. We also keep wire cable & brake cable put into the heat shrink hose.

Every components are interrelated, the bottom bracket BB90 has worn out, hence new bearings are pressed in using Enduro bearing presser.

(Warning: Frame may broken or widen the BB cup if the bearings does not press in align with the cup)

Yea, its only one time job! Hence our bike builder carefully putting all the components make sure its neat and perfect.

Product highlights:
+ Shimano Ultegra Di2 R8150 Groupset
+ Bontrager XXX VR-CF Aero Handlebar
+ Enduro BB90 Ceramic Bearings
