Product Details

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. This has been and continues to be the go-to crank for thousands of mountain and singlespeed builds where riders are looking for a simple, proven system that performs year in and year out.

FAQ’s

• I want an ENO with a White Industries chainring and bottom bracket.  What parts do I need?
  • You will need our Square Taper Bottom Bracket available on the Bottom Brackets page.  But note they only fit BSA threaded 68mm and 73mm bottom bracket shells.
  • The chainring depends on 1x or 2x set up.  We make four different styles which are available on the Chainrings page.  Refer to the “Chainlines” chart above to see what spindle length you’ll need to match your intended chainline.
    • Square Taper ENO series TSR 1X chainrings
    • Square taper series v2 VBC 2x chainrings
    • Square Taper ENO series “Double Double” 2x rings
    • Square Taper ENO series “Bashguard” 1x rings
• How can I figure out if the ENO Crank will fit my bike?
  • Generally speaking, if you have a BSA threaded bottom bracket shell and are replacing a SRAM or Shimano mountain crank, the ENO Crank will fit fine.  Your frame’s manufacturer should have some basic guidelines on what type of crank you need, i.e., “Mountain”, Road”, or “Gravel”.  If they say it will fit a Shimano or SRAM mountain crank, you’ll be fine.  Refer to the “Chainlines” chart above to see what spindle length you’ll need to match your intended chainline.
• What bottom bracket do I need to fit the ENO Crank?
  • Our Square Taper Bottom Bracket available on the Bottom Brackets page.  But note they only fit BSA threaded 68mm and 73mm bottom bracket shells.
• Can I use a different brand bottom bracket with the ENO Crank?
  • Yes, as long as is has a J.I.S. square taper spindle. Our cranks are not compatible with “ISO/Campy” bottom bracket spindles
  • Shimano UN52/54/55 bottom brackets not recommended and will void our warranty
    • These are super cheap with funky tapers and can cause our crank arms to crack
• Can I use a different brand of chainring with your crank?
  • No.  No other brands of chainring swill fit.
• Can I use the ENO Crank on my mountain bike or single speed?
  • Yes.  The ENO crank has a similar chainline to Shimano and SRAM mountain cranks so most of the time the ENO works great on mountain bikes.  Just make sure you choose the correct spindle length on the bottom bracket to match your intended chainline.  Refer to the “Chainlines” chart above.
• How can I restore that shiny silver finish on my polished raw aluminum White Industries cranks?
  • Use “Mothers Mag and Aluminum Polish” with a microfiber rag.  Start with heavy pressure and lighten up towards the end
• Where can I find replacement parts for my cranks like extractor caps and mounting bolts?
  • Go to the Parts>Crank Parts page
  • Are crank boots/protectors available for the ENO cranks?
    • We do not offer them and are not aware of any that are compatible.
• Can I use a power meter with the ENO Cranks?
  • It’s certainly possible if you can find one that is compatible with our crank, but as of now we’re not aware of any that are compatible.
