Just add a pump to the WTK-2 Essential Tool Kit and you'll have everything you need for a mid-ride adjustment or if you need to fix a flat. This kit contains two TL-1. 2 tire levers for removing the tire to access the flat inner tube and a GP-2 pre-glued super patch kit to cover up the culprit of the flat. The patch kit features self-adhesive patches so you don't have to worry about glue coverage or having to wait for it to dry. Simply sandpaper rough, clean, apply the patch, and you can reinstall the tube, inflate, and continue on with your ride. If the flat is a little more serious and you've torn the sidewall of your tire, this kit has you covered there too with two TB-2 tire boots. The seriously strong, waterproof, vinyl patches with adhesive backing holds the boot in place preventing the tube from pooching out of the tire, again saving your ride. If something finds its way lose or you need to make an adjustment like raising or lowering your saddle height, the AWS-9. 2 fold up hex wrench set has popular tools to make the fix. The tools and patches fit in an easy to carry nylon pouch that you can throw in your pack or saddle bag.
