First was the bottom bracket. This is the axle that the crank arms attach to.
Then the crank arms, pedals, and front derailleur.
The quill stem adapter. The stem and handlebar will mount on this.
Then the seat post and seat adjusted for Katie's legs.
And last it was the derailleur hanger and rear derailleur.
Next will come the wheels and tires. Once I get the wheels I can install the rear gear cluster and chain.
