Blue Lug Square Taper Crank Self Extractors


Square taper cranks might be going the way of the dodo, but we still think they make sense for lots of applications: touring, road, commuting, repurposing into cool door knobs.  Pulling a crank arm with a Park or similar crank extractor is a bit of a scary proposition.  I’ve seen more than one crank extractor fall to the floor when the crank threads stripped out.  This happens because the extractor tool isn’t seated far enough into the crank, or someone bodgered the threads previously.  Self extractors keep those issues from happening.  Install a standard 8mm hex crank bolt, and then use pin spanners to thread these brass self extractors into the cranks.  Thread them in till the flat exterior of the extractor is at least flush with the cranks.  Then, when you want to pull the cranks, simply loosen the crank bolts, and slowly pull the cranks off.  Dead simple, very handy.  Also, they look nice.  

Make sure threads are really clean before you install, and make sure you have good crank bolts, not janky old rounded out ones. 

Grease the inner face of the extractor, these do NOT come with washers.  That's fine, if you grease.

SOLD AS A PAIR.  One crankset worth.
