Park Tool SR-18.2 chain whip
$ 34.95
Who rides a track bike and doesn't own a proper chain whip? Friggin' kooks, that's who. Don't be a friggin' kook.
This works on both 1/8" and 3/32" cogs.
Pro tip: If you ever break the little pin holding the long chain to the handle (and you definitely will), it's very easy to fix by reattaching the chain using any 1/8" master link.
• 1/8" chain fits all fixed gear cogs
• heat-treated steel construction with molded handle for comfort
• 1" box end wrench fits all Park Tool bottom bracket & freewheel tools
• shop quality for a lifetime of use
