Not just for Mountain any more!<br /><br />"This is our “Old School” mountain and single speed crank designed for J.I.S. square taper bottom brackets. What does “ENO” stand for? It’s “ONE” backwards and mirrored, a CNC programming error made years ago that we decided was kind of cool. So instead of “ONE” (a nod to the fact that single speeders loved this crank), we say, “ENO”, like Brian Eno. Made here in our shop, the ENO Square Taper Crank draws on over 30 years of crank manufacturing experience with a focus on all the White Industries hallmarks; functionality, durability, and clean design." -the White Industries website<br /><br />...See!? A history lesson and everything, yet, no mention of Mountain anything. You should put them on some other kind of bike and see what happens!<br /><br />These crank arm sets include self-extracting crank bolts and a lockring. They are available in polished silver or hard anodized black. I usually try to get these in with the classic bronze extractor caps, but sometimes I forget and get color matched caps instead. <br /><br />Available in lengths: 165mm, 170mm, 175mm and 180mm<br /> <br />Everything else sold separately.<br /> <br /> Made in the U.S.A.
