International Orders

We can sell and ship some items internationally but certain brands or substances may be prohibited from shipping outside of U.S. or to certain territories.

We are unable to estimate local taxes and VAT and are not responsible for any of these charges or duties.

Package forwarders may be utilized at your discretion. We are not responsible for any damage that occurs after your item has been delivered to the shipping address. All shipments need to be inspected prior to being forwarded to secondary destinations.

Lead Times

We under promise and over deliver. Although many products will ship the same day or next day, our official policy is 2-4 business days of handling time including expedited orders (Next Day Air, etc.). If you need something in a rush please use a premium shipping service and contact us prior to placing your order for a more accurate ETA.

Certain items containing lithium batteries, compressed air or hazardous materials may only be shipped within the contiguous U.S. using ground delivery only.

Oversized items, including bikes, may not be available for expedited shipping. We will contact you should in the event that your selected shipping service is unavailable for your order.

Bike Builds

All bikes are built, checked and test ridden prior to boxing and shipping. This process averages 1-3 weeks depending on our backlog and the complexity of your build. Expedited builds are available for an additional fee, contact us for details.  

Complete bikes are packed in our own specially designed bike boxes but do require some basic assembly. If you aren't confident in your mechanical abilities please have your local shop do the final assembly. 

Most bikes over $3000 are eligible for free shipping. Bikes under $3000 and other certain bikes require a $199 shipping fee

We do our best to protect everything we ship but accidents do happen. Please keep all packaging and contact us within 24 hours of receiving your order so we can file a claim. 

Details

Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061-T6 aluminum. They are designed to be lightweight, strong, and durable. Our headsets have three levels of industry-leading custom sealing to protect bearings from the elements and prolong the life of the headset. This has a stack height of 3mm and is available in a variety of colors to match other Wolf Tooth anodized color options. These IS headsets are made exclusively for Specialized frames with molded-in internal bearing cups. Like all Wolf Tooth Premium Headsets with Enduro stainless steel bearings, the Premium IS Headset for Specialized has a lifetime warranty.  

Compatibility

  • Any Specialized bike that uses an IS (Integrated Standard) headset with 42mm upper bearing diameter.
  • Uppers and lowers sold separately. 
  • Enduro stainless steel sealed bearings included on both the upper and lower.
  • Upper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes. For forks with carbon steerer tubes you will need a compression plug (sold separately). (Never use a star nut on a carbon steerer tube).
  • Some bikes, like the Stumpjumper EVO, have an adjustable headset that resembles a ZS headset where an upper cup is pressed into the frame. Our bearing will fit into that cup and our top cap will fit neatly on top. 

Measuring to determine compatibility with your Specialized frame

  1. Disassemble the headset, remove upper bearing from the frame
  2. Use the depth blade on a caliper to measure from the top of the headtube to the corner where the 45˚ taper starts
