Tires
- Bontrager Montroase Comp
- 30 TPI, 29 × 2.4" - These are the tires that come with the bike. They seem reasonable, though they may be heavy. If Tim doesn't like them, we can upgrade to something else.
Computer & Light Mounts
The stem is Blendr compatible, and the bike has a garmin mount for a bike computer.
In the future, Tim might want to have a light mount as well. If so, we'll need to get another Bontrager Comp & Legacy Elite Blendr Base W540565. I should probably get one now so we'll have it when that day comes.
Saddle
Tim wants a seat for fat asses.
Oh, this bike doesn't have a dropper post. We might want to consider that for an upgrade. The frame has routing for it.
