A23 650B Disc Clincher Set 22.5 mm Deep 28 Wide

Great for off road riding of any type.  The disc specific, tubeless compatible rims have 28 spokes for extra durability.  The hubs have options for either quick releases of thu axle and the rear hub has options for either Shimano or Sram X1 cassettes.  The rims are 28 mm wide (23 internal) and 22.5 mm deep.  All wheels are custom hand built here in San Luis Obispo CA.  We use dual internal washers on the drive side rear spokes for added durability.  The hubs use dual contact sealed cartridge bearings for a super smooth ride.

We use Loctite 242 on the non drive side spokes and on the front spokes during the building process (no lubricant).  On the drive side rear spokes we use a lubricant to build (nothing special - just something slippery) and after the build put some Loctite 242 in to finish them off.   The Loctite 242 will make the spokes harder to turn but will not sieze them.

 

Nipples  Alloy 14 gauge uses Park Black Spoke wrench

Used internally on the drive side rear spokes.  I have them custom made by Boker's in the US.  They provide an extra layer or durability while adding almost no weight.  Weigh less than 1 gram each.

Black nylon.  If you are going tubeless you need to buy the Stan's rims strips.  These will not work for tubeless applications.

  

When you receive your wheels it will include a package with the extra spokes, skewers, a spacer (if a Shimano-Sram cassette is ordered) and some documents.  The documents will list the builder and on alloy wheels a serial number (which is under the rim strip near the valve hole on both wheels).  Also included is a spec sheet showing the type and length of spokes used and the spokes tensions for your wheels).  There is also some maintenance info and whatever else I want to throw in there along with a copy of your invoice.  We keep a record of your info here so you can contact us with either your invoice number (preferred), serial number (also OK), or your name and we can pull up your records.
