TUBELESS TIRE PLUG TOOL

An included tire lever, tire plug fork and tubeless plugs provide a quick fix for pesky trailside punctures.

VERSATILE CHAIN TOOL

The BC18's versatile chain tool can break any 8, 9, 10, 11, or 12-speed chains, and can also install 10, 11, or 12-speed connecting pins. In addition, a magnetized chain link storage on the body of the multi-tool can hold a 10, 11, or 12-speed quick-link.

CO2 INFLATOR

The included CO2 inflator is compatible with any threaded CO2 cartridge, and the BC18's mounting bracket can store a standard 16g/20g/25g cartridge externally. Simply thread the CO2 cartridge all the way into the inflator, push the inflator onto your wheel's Presta valve, and back the cartridge out a quarter turn to inflate.

SPOKE WRENCHES

The included size #0, #1 and #2 spoke wrenches keep the wobbles at bay and your wheels running true.

The only socks I will buy
Size: 6-10, Color: Halo Gray/Assorted
These are hands down my favorite socks to wear with tennis shoes. Bought my original 6 pack in the store, liked them so much I went buy more and they were gone. These don't slip on your heel like most socks do. Come up high enough on the top of your foot to protect from tongue rubbing (I giggled when I wrote that) and they come in fun colors. Love they are ultra no show and provide padding but people can't see them with shoes on. Five stars!

Socks
Size: Medium, Color: Black
Amazing socks. Fits Amazing. I tried to buy the six pack and it wasn’t the same. Thinner material. The 3 pack is great. Would buy again if it comes up.

Amazing socks but false advertising. They changed them.
Size: Large, Color: Black (6-pairs)
Okay well I have 4 stars because these are the best socks ever, infact, I threw out all my other socks and switched to just these. No show and they never slip. THE PROBLEM NOW, all the pairs I ordered before had a white symbol, and every time I buy more they have the grey and they are not as low show as my others… I wanted to simplify life and have all the same kind, no matching of colors or slightly different shape, but 4 times now I’ve ordered white symbol and gotten thicker longer ones with gray symbols. I’m considering switching all of my socks to the gray…. But the white symbol ones are way better, they don’t show with hey dudes on and gray symbol ones do now. I’m at a loss. Can someone tell me where to buy 100 pairs of white symbol so I never need to buy another sock again in my life?
