Giant Reign Restoration: Replacing Chainring & Bottom Bracket

Hey TH-cam,
In this video, I show you how to replace your chainring and bottom bracket; two easy parts to replace, but difficulties can arise if you are not careful.
For the chainring, there are two things you need to pay attention too: number of teeth, and bolt circle diameter (BCD). The number of teeth on the chainring (especially if it's a single ring in the front) is going to make a big difference with how the bike descends and climbs, so you need to decide what chainring you need based of off your riding style. For the BCD, here's a link to help you measure or figure out your size: www.wolftoothc...
For the bottom bracket (BB), there are many variables that need to be considered: BB style, BB thread types, size, and installation. Here is a good website to help you understand bottom brackets a little more: www.parktool.c...
Tools: depending on what type of bottom bracket you have will determine the tools you need. For this video I used the BBT-9 from Park Tool.
Please leave a comment or question.
Best,
