Since I've never done this before, there were quite a few things that I required. (Namely, everything)
I wanted to give everyone a list of everything I purchased, as well as the cost, to give you a general idea of what a first-timer is looking at:
-- Required parts and tools --
Bridgestone 180/80-14 Standard TR-4 Straight Metal Stem Tube - $21.99
(No shipping, because Honey gave me a coupon code for free shipping)
Tire Spoons - $19.99
Torque Wrench - $37.85
(Mine went MIA and I'm not riding down the street with a loose bolt)
YITAMOTOR Universal Paddock Lift Stands $75.98
(Not completely necessary, as there are other ways to lift a bike, but I live alone and I wanted something secure)
-- Not Required --
Bead Buddy II - $15.29
(I've seen how helpful these are when you're trying to push the tire back under the rim)
Motion Pro 08-0357 Rim Protector - $8.99
(Didn't want to scratch my new rims lol)
Ride-On Tire Balancer and Sealant - $15.95
(This should help balance the tires and quick-fix a screw in the tire, in the future. Much cleaner than Slime)
Total cost for a first-timer - $196.04
Keep in mind that I didn't have most of the tools and I also bought extra things that weren't necessary. I also have a tire inflator, ratchets, wrenches and other various tools, so those were saved expenses.
The mechanic wanted $21 for the tube (same price I ended up paying) and extra $81 to install. Their total would have been $102, but that's every time I get a flat. There's lots of construction in the are where I live, so I doubt this will be my last flat.
Now we wait for everything to arrive.
