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.

Specifications

Size: 29 er Clincher

Weight 1620 grams (without skewers or rim strips) weights can vary by about 50 grams a set due to rim, spoke, and hub weight tollerances.

Rim (for more information on rims and wheel building go to the rim page)

Rim Material Niobium Alloy. Sleeved seam.

Drilling: 28 hole front and 28 hole rear

Rim Weight 465 grams

Rim Dimensions 22.5 mm high 28 mm wide (23 internal).

Spokes

Spokes Sapim Laser or CX Ray 4.1 grams each Double butted 2.0-1.5-2.0

Spoke Tension Front: 130 KGF (on a Park Tensiometer 20

Spoke Tension Rear Drive Side: 165 KGF (on a Park Tensiometer 17).

Spoke Tension Rear Non Drive Side: There is no spec for this because it is whatever it is to pull the rim to the center of the wheel. They will always be looser than the drive side spokes and often by quite bit.

Note: Wheels come with extra spokes and the exact length is indicated on the spoke package. We occasionally substiture when we are out of a particular length.

Spoke Prep

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.

Spoke Nipples

Nipples Alloy 14 gauge uses Park Black Spoke wrench

Spoke Washers

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.

Hub (for more information on hubs and servicing go to the hub page)

Cassette Body Bearings: 6902 Cartridge bearings Abec 5

Front Hub Bearings: 6802 Abec 5 sealed cartridge bearing with seals

Rear Hub Bearings: 6802 (both drive and non drive side) Abec 5 sealed cartridge bearing with seals

Note: On Shimano-Sram cassette bodies (they are one in the same) you will need a spacer if using it with a 9 speed cassette (which is included in the spoke package), for a 10 speed cassette (which is narrower than a 9 speed) you will need the included spacer and the one that came with your cassette. If your cassette doesn't have one you can get them at any bike shop. They are 1 mm wide.

Skewers

Skewers weight 46 grams front 50 grams rear. Included with non thru axle options

Rim Strips

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

Documentation

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.

Tubeless

These wheels can be set up to go tubelss with the Stan's system and with the use of a tubeless specific tire. The tubeless specific tire is vital because they use a kevlar (aramid) bead that will not stretch. Using a regular tire risks a blowout - which on the front can be extremely dangerous.

Great Gravel race wheels 04/15/2021
By JJ Aulisio
Great pair of wheels for a gravel grinder race. These replaced the stock wheels on by gravel grinder bike and shaved of plenty of weight at a reasonable price. They roll fast and are bombproof. I hit some washboard on a gravel section hard enough to dislodge my water bottle but these wheels just kept rolling fast enough for me to win my age group. If you want to save money over some other pricier brands with no time penalty, get these wheels. John knows how to build great wheels.
