Shimano Bottom Bracket BB92 [ Ссылка ]
Installation of the Race Face BB92 Press Fit Bottom Bracket on the Scott Spark 900 RC frame.
Using a home made bottom bracket press, i install the bottom bracket into the bottom bracket shell of the spark 900 rc.
The Shell measured 89.5mm so i used a 2.5mms spacer on the drive side to get to 92mm. Outer width is 96mm which is the width of my shimano XTR crank.

Build Rational
I test rode the Scott 900 RC frame at the Fat Tire Festival in Ocala in February and loved it.
I am building this bike from the frame up instead of just buying a pre -built Scott 900 RC because Scott did not offer this frame with the drivetrain option I wanted.
I am building the bike with a 1 x11 Shimano XTR Drivetrain with Di2 XTR Shifting
Regular Mechanical shifters require too much force to engage the shifter for my injured right thumb and wrist.
I have altered the spring mechanism in the XTR Di2 shifter so there is significantly reduced pressure to shift. (see video on Changing XTR Di2 shifter springs)
Youtube Video Playlist on the Build
I have never built a bike from the Frame up before, I am an amateur bike builder so these videos in no way are an expert opinion.
I put this on youtube.com so other amateur bike builders could benefit from my experience if they are considering a bike build project of their own.
I am sure I will do things in these videos that may be incorrect or at least not the best way to do it.
Please leave Comments on Corrections that you think need to be made and I will make annotations in the video to correct.
