Description of Wolf Tooth Elliptical - Direct Mount Chain Ring for SRAM BB30 Short Spindle - Narrow Wide - black

Nobody won't try to convince you that elliptical (or oval, the same thing) chainrings will change your life...but they might! What Wolf Tooth can say for sure is that they have a different feel from round rings and can provide an efficiency benefit and smoother power output for some riders. Testers report the biggest benefits on punchy single track and hills, allowing less shifting and faster acceleration.

The proprietary design has ovality of 10% and timing of 112° after TDC (top dead center). These values provide the benefits of an oval ring without the drawbacks of greater ovality or more aggressive timing. The simplest way to explain how they "feel" is that where your pedal stroke is weakest it feels like you have a 2 teeth less on the chainring and where you have the most power it "feels" like you have 2 more teeth. Example: a 34t chainring feels like a 32t in the weak part of your pedal stroke and a 36t in the part of the stroke where your legs have the most power.

Compatibility of Wolf Tooth Elliptical Direct Mount Chain Ring for SRAM BB30 Short Spindle

  • These are 0mm offset flat direct mount chainrings to fit SRAM cranks.
  • These direct mount chainrings will replace your existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle. You will use these same 3 bolts to attach the Wolf Tooth SDM (TM) chainring.
  • Provide a great chainline on most boost bikes.
  • They only fit on BB30 short spindle SRAM cranksets
  • The ONLY exception to mounting them on a BB30 short spindle is when using a Fat Bike crankset (X9 or XX1) designed for a 170mm spaced rear hub on a 190mm space rear hub bike.
  • You will need chainring to chainstay clearance for a chainring 2 teeth bigger than the Elliptical chainring (max diameter is that of a chainring 2t bigger).
  • For 1x9, 1x10, or 1x11 drivetrains
  • Compatible with all 10 and 11 speed chains
  • If using a 9 speed drivetrain use a 10 speed chain (shifts and works well on a 9 speed drivetrain and fits the ring tighter for better chain retention)

Tech Specs of Wolf Tooth Elliptical Direct Mount Chain Ring for SRAM BB30 Short Spindle

  • Chainline is 50mm.
  • All chainrings feature the Drop-Stop tooth design and are made from 7075 Aluminum
  • Maximum diameter is that of a chainring 2t bigger than the size you order (so be sure there is adequate chainstay clearance!)
  • If you plan to ride in very muddy conditions, Wolf Tooth recommends a chainguide or chainkeeper in addition to a clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck.
  • A T25 Torx wrench is required to remove the bolts that secure the the chainring or spider to the crankarm.
  • An L-wrench works best since the crank spindle may contact a socket adapter and prevent it from engaging properly.
  • Use the same 3 bolts to attach the Wolf Tooth ring or if you need, we carry replacement bolts
  • Designed and manufactured in the USA!
